From: Lewis Wright > > Turn on notices and maybe even strict messages (in your development > environment), and PHP should warn you of any deprecated code. Easier said than done. I don't have an IDE available. I have tried the Komodo editor and am now playing with Eclipse/PDT, but neither of those comes with a local interpreter. My workstation is Win-XPPro and the development/test server is Apache 2.0.55 running on a RHEL 5 VM in an ESX server farm. Each project gets a set of virtual domains and matching directories. There is also a unique base directory for each code release, so I don't even know if I can figure out how to map a debugger into that environment. Currently I use WinSCP to copy files to my home directory and log in with Putty to move them to the target directory. But it is running PHP 5.2.3, which I don't think will tell me much about the newer releases. I have asked, but we don't have a process in place to update that. Sometime in the _near_ future I have to investigate whether there are security fixes since then that we should get.

Arggh, my head. So does that mean if I go back in time and > shoot my grandfather, then nobody is in the woods to hear PHP try to > compile? The compile process parses the text of the source file and translates it into an alternate form. This can by byte code, ala Pascal and Java, or executable code, ala COBOL and C. An interpreter, on the other hand, simply parses the source file, line by line and executes each line as it reads it, usually without saving it in an alternate form. This is the way JavaScript works. Some languages, such as Perl, are somewhere between the two. Perl parses the whole file, then executes only if it did not find any syntax errors or undefined variables (if certain strictures are turned on). Otherwise it prints out only the error message. >From what I have seen of PHP, it is strictly interpreted. i.e. a line is read, and executed. Then the next line is read, and executed. etc. So there is no way to get it to block execution from the beginning even when there are fatal errors. It will already have printed out as much of the page as it executed before it finds those errors. This works fine in a development or test environment, but is a serious problem in production. So, I believe the question that was actually asked, is there any way to induce PHP to completely parse the source file(s) and report any errors before printing out anything, even the HTTP headers? Or can I set it to redirect to an error page instead of sending an incomplete target page with error messages that might reveal information I don't want exposed?

That's an interesting string of buzzwords, but it carries no meaning for me. Would you care to elucidate further? As far as the code I am working with, I inherited over 160 files of mixed HTML and PHP, where the logic and presentation are intermingled (mangled) throughout. My initial toolset was TextPad4, WinSCP and Putty on a WinXP workstation, with Apache on RHEL 5 as the server. (The original coder used vi on a clone of the server until they took it away from him.) The chances of re-implementing the entire project are roughly equivalent to a zero with the edges rubbed out. I already have a six month to-do list just adding the new features already requested by current clients.

Even the core section of each page is included from the initial file. That way we can change the appearance, or modify the links to our disclaimers and help files just once and every page gets updated. We also have configuration flags to prevent some of those files from being included in a specific virtual domain, so our clients can provide their own templates instead of using ours.

First to display the input form, then to show an image selected by that input. So, either you need two code paths, or two pages. You can start off by checking the input fields and if they are empty, simply display the form. Then the next time through, when the fields are populated, insert the selected image.

This is one detail that I have not seen a good explanation for. When PHP opens an included file, it defaults back to HTML mode. You must have the PHP tags to force it into PHP mode. This is true no matter what file extension you have on them. So if you want to use PHP style comments, you must wrap them with the proper tags.

You also need to be aware that on 32 bit Unix and Linux systems the behavior of mktime() on dates after Jan 18, 2038 is undefined. The 32 bit counter overflows early on the 19th, so any value returned is invalid. This is not a problem on 64 bit systems.

Unfortunately, this code was initially inherited from another project and already had mktime() based date calculations throughout (in 19 of 162 files). I'm the fourth programmer to work with this project and now have to correct these problems. There are several other programmers who have to correct it in their projects as well. None of us wrote the original code, so we are all in the same boat. No matter what we want, we can't just replace code wholesale because of the testing overhead and other task priorities. We can only fix it after it becomes recognized as a problem. The other issue is that I don't do OOP. After 30 years of writing procedural code, mostly assembler, PL/M and C, I simply don't see the point of OO, nor can I justify the additional overhead. I have written functions that others converted into methods, and occasionally re-use functions that were written as methods, but have never used a whole class.

That was what triggered this question. Templates are a black art to me. I don't even know where to begin to understand them. Every reference I have looked at so far assumes that I already understand the MVC pattern, which is also one of the dark arts. Let me put it simply. I can't grok OO. I tried to do OOP for several years, but it simply does not make any sense to me. As a direct result, I don't understand the concept nor application of patterns. So how do I figure out how to use templates without having to absorb those first? Can I learn enough this way to determine if a site can be converted from the current state (PHP and XHTML spaghetti) into templates and begin that transformation?

Of five developers doing PHP at the moment, two are primarily using OOP. But I spent 3.5 years as part of a team developing MS-Windows services in C++. After all that time, I was only able to write basic functions for others to convert into methods or classes. I could eventually find my way around in some of those classes, but it seemed that every time I figured out what was where, somebody "refactored" a major component and I had to start all over again. All I saw was a lot of unnecessary overhead and obfuscation which made little sense in the long run and slowed down both the development and the application. The result was a handful of DLLs that are shared between several products, and each time anything is changed in one of them, every product needs to be retested to make sure nothing got broke and some have to be recertified for PCI-DSS as well. So you are telling me that I can forget about trying to use templates. Since I can not understand OOP, there is no chance I will be able to use them. Just knowing that will probably save me several weeks of frustration. Thank you, Bob McConnell -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well, I installed CodeIgniter on one of my home servers last night, but have not yet started through the manual. That will be an interesting experiment. I am hoping to create a simple recipe management system there, similar to ReciPants, but in PHP. At work the problem is more basic; 162 files of interleaved database access, business logic and presentation, all written by a civil engineering student with no software training at all. He has moved on, but five of us working on three products are now dealing with the mess he left behind.

There are too many other tasks in the backlog that are more important and will bring in real money as opposed to just making the developers' lives easier. In addition, the current application has already passed the PCI Level 1 audit, has been deployed and is now handling a thousand transactions per day. If I can slip the changes in piecemeal with those other tasks, fine, but starting over is not even an option. All three products combined are processing more than 10K transactions per day. That spells success as far as management is concerned. With a long list of client requested enhancements already assembled, code maintenance issues are not even open for discussion.

Hi Rob,
Unfortunately, you still don't understand the problem I have. While it
takes a while to puzzle out the details, I don't have any trouble
reading, understanding or debugging code like this, even though you
skipped completely over several major components (*). I have even
modified existing methods and made minor adjustments to classes, _once
they have been written_.
What I can't do is take a problem description and turn it into classes
that will actually solve the problem. I can usually turn it into
procedures relatively quickly. I can and have built real-time,
multi-tasking and multi-threaded applications on a variety of kernels
and operating systems with no significant trouble. I have written device
drivers, interrupt service routines, message queues and I/O buffering
routines without spending a lot of time thinking about them.
But defining objects and then figuring out how to create and use them
completely escapes me. My mind simply won't map a problem into objects,
it only sees procedures. Even when I look at classes, they resolve only
as loose groupings of functions and variables, not as unified
components.
If anyone knows how to fix that, please tell me. In the meantime, in my
continuing effort to eschew obfuscation, I will stick with procedural
programming.
Bob McConnell
(*) For example, "$this->" suggests you have added an array of pointers.
Some are pointers to functions (aka methods) others are pointers to
variables (aka members). But there is no indication where this array
came from, what it means, nor how it affects the code structure. From
experience I know that "$this->" is not always needed, but the C++ rules
for when it is or isn't are neither clear nor consistent. There are no
declarations nor assignments for it. It simply adds another level of
obfuscated dereferencing that needs to be done in my head to understand
what is going on.
You also failed to explain what "new" does, or "parent::__constructor".
What is the relationship between a class and an object? I get frustrated
because of the extra overhead required to instantiate an object with its
members before they can be referenced, instead of simply being able to
use them at any time from anywhere in my code. Likewise, having to pass
a pointer for one object to another object before the second can call
the first is also counter-intuitive. They're all part of the same
application, why doesn't the compiler take care of those details like it
should?
Obviously, I don't expect answers for these questions, but hopefully
this will give you a better understanding of the greater issues
involved. This is a far cry from the Fortran IV I was taught in college
40 years ago. B.M.

The carrot-Z (^Z) representation is how Unix CLI software would display it. Many control codes that didn't actually do anything were printed on the terminals with the carrot prefix. Sometimes codes that did trigger a function in the terminal would be printed that way to prevent the function from triggering. Control-Z is a left over from the CP/M days. It was used to mark the end of text files, since the original file allocation table (FAT) only tracked the number of clusters assigned to a file. Some MS-DOS and MS-Windows applications still tack it on to the end of files. I guess that's their idea of backward compatibility.

Hi Grant, First off, I believe you are asking on the wrong list. Server security is an advanced topic, well outside the experience of most novice PHP developers. You would be better off asking on some of the advanced Apache or Perl Monks mailing lists. Second, from your brief description, I can easily picture a full time job with lots of overtime hours, not something most consultants will be interested in. Security is not easy to do correctly, particularly if you are not responsible and accountable for the outcome or don't have full authority and management support. We currently have a team of five people who are jointly responsible for the security of our servers and networks. Each of them spends more than 20% of their time on that portion of their job. And finally, there are companies that do what you asked for. Gibson Research(*) is the first one that comes to mind . They also provide monitoring services to keep an eye out for intrusions on your servers once they have been hardened. Foundstone(**) is another .

I dont know a better way to do that. The strategy depends on how complicated the database is. If it is single table, then Oracle can export that to a CSV file which MySQL can import. You simply have to make sure the column types match. If it is more complex, then you need to spend some time translating the relationships from the Oracle schema into a MySQL schema. There is no one to one correspondence here, in spite of the promises of the SQL standards. Once you have done that, you may still be able to use the CSV files, but will need to determine what order to import them and how to restore the relevant indexes.

There is no way to do that in a single select. You need to have at least two and possibly three queries to answer your question. First you get a list of authors where their name begins with 'A'. Then you use that result to select a list of all books with more than one author. Then you can use that result to select all authors for them. Everyone has told you this requires processing beyond what SQL can provide. Why is that a problem?

As long as you escape you SQL correctly using > mysql_real_escape_string() or the equivalent, you should be OK. Let me see if I got this right. The data you got from the form tries to set up a local variable, assigns it a hex string as a value, then tries to execute it. That definitely looks like an attempt to crack your server. It looks like the semi-colons were removed somewhere, so none of it actually runs. But you would probably need a set of dis-assemblers to find out what CPU that code was written for and what it actually does. Next question: You said there are multiple comments like this. How do they differ, if they do? Possibly they are trying code for different CPUs. Did you trace these back to the logs to see if they all come from one IP or subnet? Is there anywhere to report these attempts that would actually do any good, or should you just ban that IP. But this one goes into my journal as something to be prepared for.

There is an entire branch of computer science and a lot of tools (lex, yacc, etc.) dedicated to that topic. It's not a bad idea, but there is one precarious assumption that underlies it. Can you absolutely guarantee there will never be a second, or third, or more pages on that server that will need some of those functions or classes? As soon as the site begins to evolve and grow, you will have multiple copies of many of those snippets, and when (not if) you need to modify them, you will have to find and change every single copy. So you need to ask yourself if this strategy is maintainable in your case. And will it make any real difference in the end?

I don't think it makes any difference what Oracle does with it. I believe most or all of the core source is available under the GPL. So it will always be available. There is certainly enough interest in the application that it will attract a number of talented developers no matter who manages the process. So even if Oracle dumps it, it will continue to exist in one or more forks. The only business issue will be who can use the trademark. On the other hand, there are some closed source utilities and components that may have to be recreated for any forked version.

[PHP] Encrypting email

But they will be sent via public mail servers, so the content must be protected. Knowing the first site where this would go for field trials, I suspect most recipients are using some version of Microsoft Outlook. But other sites down the road are likely to have different clients. That end is completely outside of my control or influence. All I can do is recommend packages for them to download and install. I already know I need to get a public key from each recipient before I can encrypt their messages, but that's as far as I have gotten. I did glance at the GPG site earlier, and it appears they only support the version of Outlook in Office 2003. I have a feeling this is going to get messy, at least on the deployment end.

The dirty little secret that nobody seems to know is that the RFCs
reserve Return-path for use by the MTA servers. It can be replaced by
any of them in the routing chain and is used when mail crosses into or
out of SMTP networks. If you want a return address other than From to
stick all the way through, you have to use the Reply-to and/or Sender
headers.

I've always > thought the return-path is where an email is bounced to and reply-to etc > are used by mail clients, not the mta's. The way I read it, the return-path field is used to indicate a gateway where the message entered the current email network. So a bounced message has to be returned to that gateway to get back to the network from whence it came. This is useful where traffic passes into an SMTP network from a network with an older routing mechanism, or vice versa. The intent is to return the bounce to the Sender or From address, in that order. But, since the RFC specifically says the field is reserved for use by the MTAs, it is not proper behavior for an email client to add it to the header. Reply-to is a specific instruction to the recipients client software to insert this address as To when a reply is composed. It is ignored by the MTA. If you don't want bounces to go to the From address, use Sender. It was intended for mailing lists and administrative assistants to send mail on behalf of someone else without having to forge their From address. It's also useful when you have a web site running on a commercial server farm outside your domain that has to send mail that acts like it came from inside that domain. Many border filters will block mail when the From line says it came from within their domain. So the From address can be the web server (it doesn't even have to be a valid address) while Sender indicates the address in the domain where any bounces need to be sent.

RE: [PHP] Self-Process php forms or not?
When you have it all in one file, the first thing you do is check to see if this request was submitted from the form. If not, you send the blank form. If it was, you validate all of the data. When a validation fails, you add error messages and resend the form with any fields that passed the validation already filled in. When validation succeeds, process and move on. No muss, no fuss.

RE: [PHP] Shopping Cart
They are all going to the same place, so what is wrong? To address your question, credit cards are not easy. As soon as you set up a site to accept them you must conform to a number of security and interface requirements. If you have never done it before, either hire someone that knows what they are doing, or hire someone to train you how to do it. The other option is to find a hosting site that provides both secure servers and credit card authorization services and put your web site on their servers. It took us nearly two years to get certification that our servers and software comply with all of the relevant PCI standards.

A lot depends on what you are actually going to do with them. If you need output in several different forms, then XML/XSLT might be the best way to go. But, I have seen an automated translation of the RecipeML DTD into an SQL schema, and it was not pretty. Unless you are very familiar with XML, or just want some practice, I wouldn't go there. I have been looking at this idea for some time, and have pretty much decided on a Postgres server for the back end with a custom schema. There are several features I want that are not all available in any of the consumer grade packages I have seen; like a web based front end, exclusion of specific ingredients due to allergies and being able to attach dated notes about alterations or substitutions I try each time I prepare a recipe. I just need to sit down with my collected notes and a few days to patch it together. But lately I have been spending most of my time with our grandchildren instead of the computer.

Because it responded differently to the encoded question mark than it did with the actual question mark, there may be a bug in that parser. Now whether that bug is exploitable is another matter and is not even questioned here. But its very existence is of concern when you are working with PCI. One other note I would make here. We believe that the PCI requirements were devised to protect the credit card companies from liability. They do very little to protect you or your employer.

From: Sancar Saran > And if you so much thinking about future DB change.

We currently have production systems using Postgres, Sybase ASA, Oracle and MS SQL Server. Only one product currently supports more than one, it can be installed with ASA or connect to an existing Oracle server. This unfortunate mix was brought about by several acquisitions over the past ten years. We also have a group talking about using MySQL for a portal project. One product did use MySQL prior to their switch to per server license fees, which made them far too expensive for the distributed system they were used in. So that project switched to Postgres. But what is the ADO layer going to look like in order to support any or all combinations of these back ends? How much of a kludge will it have to become? Is there any code out there that will support most of these, or do we have to write it all ourselves? Most of my SQL experience has been with Sybase ASA. I am playing with Postgres a little bit now, and the differences can be both subtle and glaring. But I don't know either one well enough to understand how to design an ADO interface, let alone how to bring in the other options.

It is a proprietary extension and not likely to ever be accepted as part of the W3C standards. As such, it won't be in any W3C DTD, but will always require a custom DTD be supplied locally.

I have recently been told that we are switching from compiling Apache, PHP and PostgreSQL ourselves to only using the official RedHat RPMs on our production servers[*]. This is coupled with a move to a managed hosting service. But since RH is not even shipping the most recent version of 5.2, I don't expect to see a 5.3 RPM for some time. Maybe it will have enough improvements to trigger an early update from them, but who knows. After they release it, it will still be a while before we pick it up, test it and deploy it. So even though I like some of the changes in 5.3, I am stuck with 5.2 for at least another year, maybe two. Bob McConnell [*] No, I don't like this at all. I see it as the antithesis of both the Open Source and Free Software philosophies. It means we give up control of some of the options we were selecting at compile time and have to settle for somebody else's idea of the perfect server. I fully expect it will come back to bite us at some point. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Explode-update-implode not working
At least not the way I expected it to. Apparently I am doing something
wrong, but I can't find anything specific that explains it. This is in
PHP 5.2.6.
Here is the sequence I am trying to implement without the database
portion. (This is typed in since the VNC I am using doesn't support
pasting from a Linux client to a MS-Windows server.)
-
$buff = "key1|value1~key2|value2";
$lines = explode ("~", $buff);
foreach ($lines as $kvpair) {
$line = explode ("|", $kvpair);
if ($line[0] == "key1") {
$line[1] = "value3";
$kvpair = implode ("|", $line);
break;
}
}
$newbuff = implode ("~", $lines);
-
$kvpair is modified, but that change is ignored by implode() with
$newbuff still containing "key1|value1".
So why doesn't the change to $kvpair get brought in by implode? What
should I do to update that value?

See the second note at

Either of these should do what you want:
$kvpair) {
$line = explode ("|", $kvpair);
if ($line[0] == "key1") {
$line[1] = "value3";
$lines[$key] = implode ("|", $line);
break;
}
}
$newbuff = implode ("~", $lines);

[PHP] Unit test platform
I need some guidance. I have looked over the PHP site and don't see any hints about using PHP interpreters for unit testing. I would like to know if this idea has any chance of working. I want to set up the development and build machines with PHP interpreters to do automated unit tests. Because we use PostgreSQL, I want to set up those boxes without any Postgres libraries and substitute FIT test stubs in their place. 1. I have to use MS-Windows as my development platform. Currently I have XP-Pro with NetBeans 6.5.1. I have played with Eclipse and Komodo Editor, which remain as possible options. I need a PHP interpreter that will allow me to write and debug FIT tests for functions already in use, as well as new code that I write or modify. 2. The production server is RHEL ES 5 with Apache 2 and PostgreSQL. I cannot make any changes to this platform. 3. The build machine is running Fedora Core (version unknown), also with Apache and PostgreSQL installed as it is also used for integration testing. I want to change this to remove the Postgres libraries so they can be replaced with the FIT back end. Integration testing would require a separate server which would also solve some other QA issues we have. We currently do both development and QA testing on this box, releasing a set of RPM files to production once they have been run through the wringer. Is this a reasonable plan? Where can I find PHP interpreters for MS-Windows and FC that will support this?

We have looked at that and it does not appear to be a workable option. Near as I can tell it can only test OO code already organized as classes. But... 1. None of the code I need to test is OO. The system was originally written as PHP 4 procedures and has not been significantly changed since then. Rewriting it as OOP has been discussed, but will not likely happen in the next two or three years. 2. I don't do objects. After 40 years of procedural programming, with the last 20 in low level embedded devices, I just cannot think that way. In addition, I learned to program using "eschew obfuscation" as my primary guideline. To me, OOP appears to be obfuscation taken to an absurd level. I'm more into the concrete and have a real problem with abstraction. So it takes me longer to read and understand other programmers' objects than to write the same functions myself as procedural code. Now, is there any support to implement unit testing without objects? Does my plan outline above have any merit?

[PHP] Problems with unit tests
I am using test-harness.php (PHP TAP Test Harness 1_0_0_BETA) and test-more.php to write some unit tests for several libraries of functions. These tests need to run from a MS-Windows CLI so they can be run on our desktops for now and can be added to the automated build process later. I have written my first tests using test-more.php to generate TAP compliant results, and they work as expected (see below - yes, both tests should fail). But when I run them with test-harness.php, the reported results are wrong (also below). The harness reports all tests passed, even if they didn't. After doing some digging, I found Bug #44908, which seems to be related. It appears the interpreter on MS-Windows is not creating the pipe file for STDOUT, so the harness never sees the results from the actual tests. I also tried using the Perl Test::Harness to run the scripts and get the same error message there. Both harnesses appear to ignore the error count returned as the process exit value as well. But I am not sure if that is true or they just never saw it. Has any workaround been identified for this problem? Is there another mailing list that might be a more appropriate forum for this issue?

[PHP] Resources for unit tests
I am using Mike Lively's test-harness.php <http://www.digitalsandwich.com/test-harness.php> with test-more.php from Apache::Test for my unit test framework. I have also begun writing stubs for PostgreSQL functions to run behind that. These tests will be run on our function libraries as part of the build process just after code is checked out from the VCS system (Perforce), but before creating the installation RPMs. i.e. if a unit test fails, report the error and don't build the RPM. I am having some difficulty with the Postgres stubs that we don't have the experience to figure out. Some functions return a resource, which appears to be a complex form of array. Is there any way to build one through PHP code, or do I even need to. Since these resources will only be passed back into a later database call, can I simply replace them in the stubs with an array? We don't expect to dereference them anyway. Thank you, Bob McConnell -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Top posting did not exist in the early days of the Internet. I was active on email listserves and Usenet newsgroups 18 years ago, long before Microsoft discovered them and decided that top posting should be the norm. All of the other news and email clients I have ever used defaulted to bottom posting. It was only in Outlook 2003 that Microsoft finally removed that option completely.

RE: [PHP] Obeying the rules (was Simple login form with cookies)
A quick search on Google indicates this argument has been active in various forums for over ten years, so I don't expect it to be resolved here. While ego is the most apparent motivator in these discussions I suspect, but have no way to confirm, that the two camps are divided by how their [email|news] client posts by default. GroupWise was the first significant email client I am aware of that top posted replies. Since that was the competitive target Outlook was created to eliminate, Outlook also top posted by default. But prior to the Office 2003 release it could still be configured to both bottom post and automatically insert the line prefixes for attribution. At the office I have to use Outlook. I hate it. Not only do I have to hand edit every message to construct the replay, there are many other problems that make it totally unsuitable for intelligent users.

My bank also does this, but it only works if Javascript is enabled when I first log in. Otherwise the initial login fails and I do it again on the second site.

[PHP] Inverting a dependency list
I recall, years ago, having a set of utilities that would build a call tree from application code written in C. This was useful for figuring out dependencies in code that someone else had written. I would like to do something similar with a large PHP application I am now maintaining, but with a slightly different emphasis. This application includes several library files which contain more than 400 function declarations. I need to determine how many of those functions are actually used by the application and which can be culled from the code base. Is there an easy way to determine which of them are called somewhere and then work through the call tree to identify the orphans?

Save each page to a text file. Sort the two text files. Run 'diff -iw' on the sorted files. Add additional flags to diff as needed.

The problem with that is if that field is a string, and not formatted as
YY/MM/DD, then a simple compare won't work in January. You have to break
it down into the three components and compare each one in turn.

If the dates are really stored as varchar, you are doing a lexical
comparison on a field that is meaningless in that context. You will need
to break the string down somewhere and do three separate comparisons.

Like all books with MySQL in the title, I'm waiting for it to be translated into PostgreSQL. We used to have MySQL in our systems, but when they changed to the per-server license fee structure we had to change to PostgreSQL. Two proposals we had in progress for distributed systems would have ended up with 80% of the price being passed through as fees to MySQL AB.

It would be easier if you kept a record of the status changes to and from busy (check-in and check-out) as a transaction log. Then you can scan the log to see the status changes for any time period. But you still have to deal with a room that stayed busy for the entire period. First question, does busy include the time needed by housekeeping to clean the room after checkout? You might want to consider a separate status for that. Second question, does the system keep track of when each room is reserved? If one is reserved for three nights beginning Friday, can it still be used Wednesday for a one or two night stay?

RE: [PHP] PHP/Ajax Framework - Call for Developers & Testers
From: Raymond Irving > Hi Nathan, > > I agree with you, and I believe that there are many persons > who don't like the idea of hosting all their applications on > a third party server. IMO there are some advantages and > disadvantages to doing so but that's a discussion in itself. Hosted servers are basically a trade off between doing it yourself and paying someone else to do it. The initial choice is between installing your own servers or spend the money to rent servers from someone else. Most of the time it is actually the network bandwidth issue that decides this. Can you afford a network connection that will handle the peak loads but be unused most of the time? But once you decide to pay someone else, you have another set of trade offs to negotiate. What services do they provide? What systems do they offer? How do they manage version control and updates? Are they PCI compliant? There are a wide range of options available in the market. Not all of them will fit your specific needs. We just moved most of our servers from a physical hosting service to a managed service. Where we used to maintain the OS and all software on the server, the new service now handles that for us. The trade off is that now we have to settle for the server package they offer. That means we get the versions of Apache, PHP and PostgreSQL that were included in the last production release of RHEL. If we want a newer version of PHP, we have to take over maintenance of that component. It becomes our responsibility to install the updates, patches, etc., for that component. Once you get beyond a private web site these types of decisions become part of the management process, just as make or buy decisions are part of the hardware procurement process. There are people out there making a good living just guiding companies through this decision making process.

RE: [PHP] Re: page works on public web site, but not on my computer
I recommend you start by replacing Vista. There are so many problems with it that Microsoft is rushing to ship a replacement as soon as possible. It remains to be seen whether Windows 7 is a real fix or merely more of the same problems. I am not aware of any serious developers writing code specifically for Vista. We only test our products on it enough to decide if we will support each product on that OS. If they don't work out of the box, we don't support them nor recommend our clients install them on Vista. There are no copies of Vista installed in the company outside of the ESX servers used for testing. I would recommend Red Hat as the replacement.

It guarantees all of the bytes written to one end of the pipe will come out the other end in the same order, but not necessarily in the same groupings. There are a number of buffers along the way that might split them up, as well as limits on packet sizes in the various networks it passed through. So you get what is available in the last buffer when a timer expires, no more, and no less. If you have serialized data that needs to be grouped in specific blocks, your application will need to keep track of those blocks, reassembling or splitting the streamed data as necessary. You could use UDP which does guarantee that packets will be kept together, but that protocol doesn't guarantee delivery.

Shawn, You're looking at it inside out. Yes, the individual packets are tracked by the stack, to make sure they arrive in the correct order. But the size and fragmentation of those packets have no relationship at all to any data structure the application layer may imply. They simply implement a communications stream to reliably move octets from one point to another. If the application needs structure, it has to manage that for itself. For UDP, if you write a 32 byte packet, the matching read will get a 32 byte packet, if it arrived at the receiving stack. Missed data detection and retry requests are left up to the application.

While I have written a lot of code to manage sockets over the years, and
coded a UDP/IP stack, I have never done it in PHP. And unfortunately, I
don't have time to experiment right now. My boss is waiting for the next
product release from me.
Getting one byte at a time is somewhat wasteful, as it requires more
system calls than necessary. That's a lot of wasted overhead.
Whether you always get one or more bytes depends on a number of factors,
including whether the calls PHP uses are blocking or non-blocking, plus
there may be ways to switch the socket back and forth.
Have you tried doing a Google search on the group of PHP functions you
expect to use. That should come up with some sample code to look at.

The return code only tells you the local server accepted the mail. It is unlikely that server knows the address is invalid since it can only validate the domain portion of the address. Only the destination server can validate the user name, and most are now configured not to report mail sent to invalid addresses due to spam. They will silently discard the message.

When SPAM generators, that had been widely deployed by virus, started sending mail with random return addresses, they forced another change in the email admin best practices discussion. For a short while the network became clogged in bounce messages sent to both valid and invalid addresses. Some of the invalid addresses even triggered infinite loops of error messages. None of the servers I am familiar with send bounce messages reporting invalid addresses any more. Our own servers won't even tell us internally when they discard incoming messages.

Mike, It's not MS-Windows, it's just Vista. Vista was designed and distributed for use as a home entertainment center. It was loaded with DRM and other restrictions to entice the RIAA and MPAA to use it as their primary platform for distributing music and movies, respectively. That pretty much broke it for any serious uses. If you can't avoid MS-Windows, at least upgrade to XP.
