[PHP] newbie questions
Guys, I am fairly new to PHP. Here are a few questions, if anybody can answer it will help me get started. Thanks I am trying to build a website and I would like to do the following in my scripts 1. I want to return response to the browser and AFTERWARDS make a log entry in to a database. I need this so user can experience a fast response. 2. If the database update fails, I want to ignore it (since it is just log entry). Something like try-catch construct in Java. This is more important if item1 mentioned above is not possible. Essentially whether I make a database entry or not, I must return a valid response to user. 3. Is there something like connection pool in php? Do usually people open/close database connection for every request (I doubt that, it sounds really slow). Some code samples or pointers to documentation for the above would also be very helpful.

[PHP] Re: newbie questions
That was very very helpful. Thanks a ton! One more question. For every request, I am sending a redirect back to the user and the browser takes the user to another url. The problem is that the browser is not redirecting until the script finishes. Even if I do flush(), the browser waits til script ends. Is there a way to force browser to redirect and not wait for the script to end? In Java I can think of many ways, one is to use threads, hand of data to another thread and return the response. Another solution would be to store data in memory (static variable) and update only after every 100 requests. Is any of this possible in PHP? M.

Thanks I am trying to build a website and I would like to do the following in my scripts 1. I want to return response to the browser and AFTERWARDS make a log entry in to a database. I need this so user can experience a fast response. There is no "before and after". Everything you do happens during (part of) the response. But you can just output your data, whatever it may be, flush() it and then log it via the same script. Your user won't notice a thing (Hell, even without the flush your user won't notice it probably). 2. If the database update fails, I want to ignore it (since it is just log entry). Something like try-catch construct in Java. This is more important if item1 mentioned above is not possible. Essentially whether I make a database entry or not, I must return a valid response to user. So ignore it :) If you don't check for errors, you won't see them... Makes debugging very annoying, but you won't see em nevertheless. If your output is not based on anything from your database-update, then there apparently is no need to worry about it. 3. Is there something like connection pool in php? Do usually people open/close database connection for every request (I doubt that, it sounds really slow). There is something like that, the persistent connections (ie. via mysql_pconnect), but generally people DO open/close connections via the same script each and every time the script is executed (this might sound very slow, but it's actually not too bad). Using persistent connections is not always the best option (and usually doesn't even make much sense); there's a good bit of documentation about it in the php docs: http://www.php.net/manual/en/features.persistent-connections.php Some code samples or pointers to documentation for the above would also be very helpful. code samples of what exactly ?

[PHP] ruby / rails within a php site
I have a regular php site. I also have a ruby / rails application. Now I want to put the HTML generated by ruby / rails application within a section of a php page. This should be similar to like calling a php function within a section, which would produce the HTML output of the php function. Is such a thing possible between php and ruby / rails? Any help will be appreciated. Thanks ravi
Re: [PHP] PDO Prepared Statements and stripslashes
Hello, The plug-in PDO has nothing to do with the backslashes being inserted into the database. The backslashes are used to escape characters like in D's...it would show D's. That's the safe behavior of it. You can change your programming code to fix that. Ravi.

Re: [PHP] All records not displaying...
I would say enabled error_reporting(E_ALL); error_reporting(-1);
Then use die(mysql_error()); with your mysql function to get some debugging
data.
Also use var_dump($query_name) to find out what is spits out.
Debugging is your best friend here. If you don't use die() or
error_reporting() then you will see a blank screen.

Re: [PHP] array question
Jim Lucas has it. You can use the preg_match function to find it. I would
use regexp for that reason. regexp is good for making sure things are typed
the way they need to (mostly used for).

Re: [PHP] PHPInfo disabled due to security
Hello there, If you have a small to medium size web site then go to GoDaddy. Do not believe all that you see from php_info(). I will give you an example. The memory_limit it gives on shared hosting does not reflect the one intended for your shared account. It shows what was set for overall use. But blocking php_info() isn't right (at least I don't think so). Ravi.

Re: [PHP] Error Querying Database
Trying to connect to the database can involve setting up your database. Make
sure that you have a valid login/password that is recognized by MySQL.
Please keep in mind that MySQL works on permission by hosts. So your host IP
must be matched with the username/password on the database for a successful
authentication. One way to know that you can connect successfully to your
remote database is to actually test it. Download MySQL Workbench from
Mysql.com and then try to connect to remote from the same host that your php
application is sitting at. If it works, thumbs up. If it does not then you
have a permission issue there. Add your username/host appropriately.
If you can connect without a hitch then you are doing something wrong on
your code. Use mysql_connect(), mysql_select_db() and then send an statement
and use the resource to see if it returns TRUE or FALSE. At this point, on
FALSE it means that you have a bad written statement.
There is so much that can go wrong. Debug step by step.
Ravi.

Re: [PHP] Problem with Include
My point is that you tried to take code from one page and put it all "organized" in another page and the include that page of includes back into the pages that you want it to feed off from. If stuff works the way that it does then there a reason for it to have been done that way. That's why documenting code is so important. 99% doesn't do it (including me). Ravi.

Re: [PHP] Problem with Include
If something is working and you don't know exactly whats under the hood then you are wasting your time in trying to re-invent your own wheel and waste your time and resources to modify something that isn't needed to be touched. Good programmers make good use of their time as well. We need to keep in check with new technology, learn new trends and also master our weakness. If we keep changing this or that or moving that or this then oh well...there goes 1 day worth of work to figure stuff out. Just my take on this. If you think different, then no problems.

Re: [PHP] Problem with Include
Hello, Good points. If you are getting paid to do that then fine. There is a difference between enhancing code and wasting time. I do my best to come up with the best I can. I always take notes to perform better in upcoming projects. It is imperative to make good use of time. Unless it is a security issue, no need to waste time. Again, if you are getting paid for it then fine. People tune cars for a reason, they want the attention or the thrill. If you want to tune your code for fun then nobody is against that either :) Ravi.

Re: [PHP] empty() in email message
Hello Gary,
Please research the difference between a single quote and a double quote.
Also, you can use the operator .=(dot + equal) in this manner:
if(!empty($_POST['fname'])) {
$msg .= "$lname\n";
} else if(!empty($_POST['lname'])) {
$msg .= "$lname\n";
}

Re: [PHP] accessing magic parent set
Hello,
$this only calls variables inside of a method. In your function, you are
calling a variable that was defined inside of your function called
$columnName. You should past the whole class. Not just the methods.
"The pseudo-variable $this is available when a method is called from within
an object context. $this is a reference to the calling object (usually the
object to which the method belongs, but possibly another object, if the
method is called statically from the context of a secondary object). " taken
from http://www.php.net/manual/en/language.oop5.basic.php
The parent keyword indicates that this is an extended class. You are
referring back to the master class.

Bob,
Thank you very much. This is good information. What I found out from
http://us2.php.net/manual/en/function.stripslashes.php was the following:
"An example use of *stripslashes()* is when the PHP directive
magic_quotes_gpc<http://us2.php.net/manual/en/info.configuration.php#ini.magic-quotes-gpc>is
*on* (it's on by default), and you aren't inserting this data into a place
(such as a database) that requires escaping. For example, if you're simply
outputting data straight from an HTML form. "
So that means that stripslashes() isn't intended for DB insertions but only
straight output. So I will remove it from my code.
Thanks,
Ravi.

Hello Russell,
When you use htmlspecialchars() it tries to escape single/double quotes with
a bunch of backslashes. I had stripslashes() in an attempt to try to get the
backslashes away but it didn't. So the solution was to disable magic quotes
in php.ini. With GoDaddy shared hosting, I had to rename php.ini over to
php5.ini in order to have this to work. Also had to include the command like
responsible for disabling magic quotes. Everything is good and clean now.
Now you type for example "Hunter's Reserve Circle" and it keeps it as it is.
Before it would print something like "Hunter'///s Reserve Circle".
With double quote, the situation would be even worse.
mysql_real_escape_string() is a must in order to avoid SQL injections.
Regards,
Ravi.
Re: [PHP] static Logging class?
Hello Lars, I would apply the Singleton Pattern where you would have 1 instance for you entire application. As far as whether or not to use a static method, I would weigh the options. If you just want to call a method that you know will not have to be changed in the future and that method will not be using any pre-defined properties, then it makes sense to call a static method. Bear in mind that static methods can not be overridden.

Re: [PHP] Introduction ... !
Hello Nick, Welcome to the list. I joined the list awhile back then unsubscribed for no apparent reason. This list was very active years ago. I came back about a few months ago just as a watcher. I didn't really post or participate at all. I guess, there are a lot of watchers "only" people here. They receive digest e-mails; they just don't participate in any way. Then, there are those who lost their jobs due to the recession and so they dropped off the list as well. There are a lot of developers unemployed. I would imagine that other developers didn't keep up with the changes. PHP has come a long way as far as Object Oriented Programming is concerned. There have been many discussions about Design Patterns and extending existing classes. So a lot has changed in the last 5 years. I do believe that the list will pick up again. Welcome back, Ravi.

Re: [PHP] Accessing Files Outside the Web Root
Hello Dale, The spiders are not the only problem. The issue here is that anyone can download your files from your website and then make them available elsewhere. In order to address the problem, you should create a "Members Restricted Area" where members only could download your files. You can then make your PDF directory only visible through your Members Restricted Area. That directory would be invisible to the web. In some Linux distros, if the file/directory is not a member of www-data, it is not visible online. But you can still link the files to your PHP page. Ravi. On Wed, Mar 13, 2013 at 4:38 PM, Dale H.

[PHP] Accessing env variables
Hi, I have defined couple of environment variables in one of my apache module using setenv() at fixups and handler function calls. I have another php module, where I need to access these variables. So I have defined these variables as "global $var1, $var2 ..etc"; When I try to access these variables as $var1 and $var2 , they don't seem to be set, so I am not getting correct values, but they give correct values when I acess them using getenv() call. I thought that the global command would make the global environment variables available in the local php code. How to access these environment variables in my php code without using getenv() call. Thanks Ravi Natarajan

[PHP] php.ini include_path and symlinks
Hi, We run php 5.2.0 + apache 2.2. with apc turned on ( apc.stat also on ). Earlier we did not use the php.ini include_path setting. We relied on some symlinks for our common code so that require_once works correctly. This worked fine and during code releases we flipped the main 'release' symlink atomically, without restarting apache. Later we decided to use php.ini include path to refactor common code more cleanly and it looks like: include_path=.:/some/dir/current:.. Now 'current' above is a symlink. When we push out a new release the current is updated atomically and apache is not restarted. This seems to pick the new changes and I ran some manual tests to confirm. However occasionally I see weird errors where it seems php could be resolving the symlink to the actual dir. at apache startup, and it assumes that old dir. When a new release goes out, we see 'fatal redeclare errors' etc.. Restarting apache (TERM and not USR1) seems to fix it. We could update our install scripts to restart apache, but I am just curious, is this really necessary? Is there anyway to prevent php from not resolving symlinks but use them as it is in the include_path?

This was the case even before we introduced include_path, but earlier, all the symlinks were to a relative path ( e.g. libraries ---> ../libs/.. ). Thanks for the pointer - I will look into this.

[PHP] apc and cli
Hi,
We have long running daemons written in php ( cli, non-apache
contexts) with the typical pattern:
while( !$shutdown )
{
$c = new SomeClass;
$c->process();
}
For performance reasons, would it help if apc.enable_cli is turned on:
apc.enable_cli integer
Mostly for testing and debugging. Setting this enables APC for the
CLI version of PHP. Normally you wouldn't want to create, populate and
tear down the APC cache on every CLI request, but for various test
scenarios it is handy to be able to enable APC for the CLI version of
APC easily.
I am slightly confused by the statement - 'Mostly for testing and
debugging.' .
On each loop iteration, does php recompile the code in 'SomeClass' (
and all its dependencies ) or it is really cached ( as it has seen the
class code once ).
If there is a php internals document on such issues, do let me know.
Thanks,
Ravi

[PHP] curl timeout vs socket timeout
Hi, We have two versions of client code, one using curl, and other one using raw sockets via fsockopen(), and we use the following code to set the i/o timeouts: 1) curl: . . curl_setopt( $handle, CURLOPT_TIMEOUT, 1 ); . . $resp = curl_exec($handle) 2) sockets: stream_set_timeout( $sock, 1); Here we use frwrite() and fread() to send the request and read the response respectively. In (1), how is the timeout applied - is it: a) timeout includes the entire curl_exec() call - the combined socket write() ( to send the request ) and the read() ( read the response ) calls. or b) timeout is independently applied to write() and read() end respectively. Some of our tests seem to indicate it is (a). In (2), I am assuming the stream timeout is applied at each i/o call independently for fwrite() and fread() - I am pretty much certain on this as this is how it would map to underlying C calls. It will be good to get a confirmation on our doubts. Thanks, Ravi -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] System errno in PHP
Hi,
I also ran into the same issue with file and socket apis, and for now, I just
hack it like ( for linux 2.6 systems ):
class Errno
{
const EINTR= 4;
const EIO = 5;
const EINVAL = 22;
const ENODATA = 61;
const EBADMSG = 74;
const EOPNOTSUPP = 95;
const ECONNRESET = 104;
const ENOTCONN = 107;
const ETIMEDOUT= 110;
const EALREADY = 114;
const EINPROGRESS = 115;
// useful static methods that use posix_strerror()
// and socket_strerror() to return strings for logging purposes...
.
.
}
Clearly this is not portable, but I am betting that usually on the
same kernel releases, they
don't usually change these numbers around.
Having PHP expose these useful constants in a portable manner would be
a big plus.
Thanks,
Ravi

[PHP] Redisplaying information from a HTML form
Hi there I'm absolutely new at this so forgive me if none of it makes any sense! I'm trying to write a page which lets you apply for tickets. I've written it in PHP and used simple variable names for all the input fields. Upon clicking submit, I want the form to be checked for incorrect formats and blank fields. I've managed to write the checking program in such a way that clicking submit launches an 'error' page which displays at the top of the page which field is wrong, and then redisplays the form. (The form redisplay is done using a function which uses the variables I used in the HTML form page). My problem is this: when the 'error' page comes up all of the text boxes will quite happily redisplay the data that was put into them, but I have a couple of drop-down boxes and radio buttons which lose their value. Is there a way I can make these boxes and buttons retain their value? Thanks Ravi Gogna -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Re: PHP programming strategy; lots of little include files, or a few big ones?
Hi, A note on bytecode caching and include/include_once performance. A while ago when we were profiling our code, we did notice that file includes do take a noticeable percentage of overall overhead (enough for us to look into it more deep). We are using apc cache on a standard LAMP platform (linux 2.6 series, apache 2.2x and PHP 5 series). Our includes were using 'relative' paths (e.g. include_once '../common/somefile.inc' or include_once 'lib/somefuncs.inc' ) and within APC cache logic, it resolves such relative paths to absolute paths via a realpath() calls. This can be fairly file-system intensive (lots of syscalls like stat() and readlink() to resolve symlinks etc...). APC uses absolute paths as key into the opcode cache. This gets worse if it has to find your files via the 'ini_path' setting (and most of your library or common code is not in the first component or so ). So from APC cache perspective, it is most efficient if your include paths are all absolute (realpath() logic is skipped) - e.g.: include_once $BASE_DIR . '/common/somefile.inc'; include_once $BASE_DIR . '/lib/somefuncs.inc'; and so on where '$BASE_DIR' could be set via apache Setenv directives ( $_SERVER['BASE_DIR'] or even hardcoded all over the place). There were other issues with include vs include_once and apc cache, but I don't recall why there were performance difference (with include only even with relative paths, the performance was better, but managing dependencies is to cumbersome). Not sure how other bytecode cache handles relative paths but I suspect it has to do something similar. >From a pure code readability point of view and more automated dependency management (as close to compiled languages as possible), I do favor include_once/require_once strategy with absolute path strategy, but it is not unheard of where to squeeze out maximal performance, a giant single 'include' is done. Sometimes this is done on prod. systems where a parser goes through and generates this big include file, and ensure it is placed somewhere in the beginning the main 'controller.php' (MVC model) and all other includes stripped off. Hope this helps in making your decision.

Re: [PHP] Re: PHP programming strategy; lots of little include files, or a few big ones?
Sorry forgot to mention that we used APC with apc.stat turned off which will give a little bit more performance gain, but it does mean flushing the cache on every code push (which is trivial).

Re: [PHP] Object Oriented Programming question
Hi Bob, [Couldn't resist jumping into this topic :)] Even if you look at traditional unix (or similar) kernel internals, although they tend to use functional paradigms, they do have a OOP-like flavor. Example: Everything in a unix system is a 'file' (well not really with networking logic, but it is one of the most important abstractions). There is a notion of a 'abstract' base class 'file', and then there are different 'types' of files - regular, directory, devices etc... So you 'instantiate' a specific 'concrete' object when dealing with a specific file. What are the methods that apply to all files? There is open(), close(), read(), write(), ioctl() etc... Not all methods are valid for certain kinds of files - e.g. usually you don't write() to a keyboard device. In unix and C, the OOP is modeled using structs (to store various attributes, or data members), and each struct tends to have 'pointer-to-functions' (listed above in case of files) to actual implementation on how to deal with such objects in the system. In fact the device-driver framework in unix can be thought of as an excellent example of polymorphism where a table stores all the specific functions that operate on the device. Grouping data and its associated operations is one of the hallmarks of OOP. In C, there is no *direct* support to express such groupings where as in C++ (and other OOP languages), there is direct support via notion of 'classes' to express such relationships. I would recommend this book: 'The design and evolution of C++' by Bjarne Stroustrup where such topics are discussed more in depth. Hope this helps.

Re: [PHP] memory efficient hash table extension? like lchash ...
PHP does expose sys V shared-memory apis (shm_* functions): http://us2.php.net/manual/en/book.sem.php If you already have apc installed, you could also try: http://us2.php.net/manual/en/book.apc.php APC also allows you to store user specific data too (it will be in a shared memory). Haven't tried these myself, so I would do some quick tests to ensure if they meet your performance requirements. In theory, it should be faster than berkeley-db like solutions (which is also another option but it seems something similar like MongoDB was not good enough?). I am curious to know if someone here has run these tests. Note that with memcached installed locally (on the same box running php), it can be surprisingly efficient - using pconnect(), caching the handler in a static var for a given request cycle etc...

If there is a > way to configure memcached guarantee storage, that might work. True but the lru policy only kicks in lazily. So if you ensure that you never hit near the max allowed limit (-m option), and you store your key-val pairs with no expiry, it will be present till the next restart. So essentially you would have to estimate the value for the -m option to big enough to accommodate all possible key-val pairs (the evictions counter in memcached stats should remain 0). BTW, I have seen this implementation behavior in 1.2.x series but not sure it is necessarily guaranteed in future versions. Ravi On Mon, Jan 25, 2010 at 3:49 PM, D.

Re: [PHP] Re: Best Practices Book, Document, Web Site?
Other than coding standards, the other good read is:
(it seems to cover most topics I have ran into while maintaining a
high traffic site implemented in php 5):
http://phplens.com/lens/php-book/optimizing-debugging-php.php
It is 'best practices' from another angle - use of opcode cache (apc
etc..), output buffering and so on.
Coding standards vary a lot, so I would recommend sticking to one
style once a consensus is reached among the team and preferably
enforce it in automated fashion (e.g.
http://pear.php.net/package/PHP_CodeSniffer/ as a svn pre-commit
hook).
The other easily over-looked part I have seen in many php projects is
the code layout and directory structure, including dependency
management (library code vs business logic etc..), and more
importantly only exposing the main 'entry point' scripts (index.php or
controller.php in a MVC model) in a apache doc root. Many times I have
seen poorly laid out code that ends up getting deployed with the
entire code bases exposed in a apache doc root. If care is not taken
(e.g. naming some files .inc and no special apache rules to interpret
them as a php handler), it is a security nightmare with critical files
getting exposed.
I have my own layout suggestion which has worked well for us, and once
mastered, it makes everyone in the team very productive. Maybe this
can be a separate topic in its own right.

[PHP] php cli question
Hi, I have some basic questions on running php (5.2.x series on Linux 2.6) as a standalone daemon using posix methods (fork() etc..): #!/usr/bin/php doSomething() } // shutdown logic. The 'someclass.php' in turn will include other files (via require_once). The above file will be executed directly from the shell. The main loop could be listening to new requests via sockets etc.. Few questions: 1) Does opcode cache really matter in such cli-based daemons? As 'SomeClass' is instantiated at every loop, I am assuming it is only compiled once as it has already been 'seen'. I am not very clear on how apc (or eaccelerator) works in such cases. 2) What about garbage collection? In a standard apache-mod-php setup, we rely on the end of a request-cycle to free up resources - close file descriptiors, free up memory etc.. I am assuming in the aforesaid standalone daemon case, we would have to do this manually? In the loop above, would it be better to 'unset($a)' explicitly at the end of it before it goes to the next iteration? Note: I have written pre-forker deamons in php directly and successfully deployed them in the past, but never looked at in depth to understand all the nuances. Anecdotally, I have done 'unset()' at some critical places were large arrays were used, and I think it helped. AFAIK, unlike Java, there is no 'garbage collector' thread that does all the magic?

@Tom: I have compiled php with pcntl on and this has never been an
issue. It works well (on a linux setup), and I have deployed
standalone daemons with out any major problems. I have a home-grown
'preforker' framework (which I hope to share soon) which can be used
to exploit multi-core boxes.
@Shawn: It is not academic. There is a follow-up I am planning based
on the doubts above. I have deployed such daemons in the past with
some assumptions on (2) by doing manual cleanups - e.g. closing curl
connections, closing up db handles etc... Really want to understand
how php works in such setups outside of apache+mod_php.

Now on my follow up question: [Note: I think it is related to the issues discussed above hence keeping it on this thread but if I am violating any guidelines here, do let me know] One reason the aforesaid questions got triggered was that in our company right now, there is a big discussion on moving away from apache+mod_php solution to nginx+fast-cgi based model for handling all php-based services. The move seems to be more based some anecdotal observations and possibly not based on a typical php-based app (i.e. the php script involved was trivial one acting as some proxy to another backend service). I have written fast-cgi servers in the past in C++, and I am aware how the apahce<>fast-cgi-servers work (in unix socket setups). All our php apps are written with apache+mod_php in mind (no explicit resource mgmt ), so this was a concern to me. If the same scripts now need to run 'forever' as a fastcgi server, are we forced to do such manual resource mgmt? Or are there solutions here that work just as in mod_php? This reminded me of the cli daemons that I had written earlier where such manual cleanups were done, and hence my doubts on this nginx+fast-cgi approach. thx, Ravi > > > -- > Per Jessen, Zürich (14.6°C) > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, visit: http://www.php.net/unsub.php > > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Not sure if it it is a typo above, are you actually passing
$msgContent in the function above? If it is a global variable, you
would need to add a 'global' declaration:
function ProcessForm($values)
{
global $msgContent;
mail('myemail:domain.com', 'Website Enquiry', $msgContent, "From:
\"{$values['name']}\" <{$values['emailaddress']}>\r\n");
.
.
.
}
Also try adding CRLF sequence at the end of the header line as shown above.

It has a OOP flavor, and considered fairly lightweight. I have written my own simplistic MVC framework which is more efficient but definitely not as feature rich as Kohana. There are good hooks for db handling (which will do input validation, escaping etc..). Ravi -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Application settings, configuration, and preferences.
I am partial to the filesystem but I can see scenarios where the db approach might be useful (single point of control) with good caching strategy using apc or other mechanisms. One approach I have followed is that if the config. field and values are simple key-value pairs, you could store them in a dedicated conf file and have it included in the main apache conf file (Include directive). This way, all the configs are accessible via $_SERVER. The separate conf file can be checked in svn, pushed separately as part of release process etc... The same approach also works in standalone php cli scripts via a shell wrapper - e.g.: #!/bin/bash . # list fields directly here or load them separately - e.g: # . /path/to/some_file.conf export FIELD1="foo" export FIELD2 ="bar" # Note: values can have some structure too export FIELD3="abc,cde,fgh" . . /usr/bin/php some_script.php You could also use the php ini style confs: http://php.net/manual/en/function.parse-ini-file.php In the $_SERVER approach above, the parsing is done at start-up, so there is no setup cost at every request. For the ini or xml parsing approach, you may need to cache the result if this parsing cost needs to be avoided on every request.
