[PHP] Regular expression problem
I just moved some *working* code from a Win2k server running PHP 4.2.1
to a FreeBSD server running 4.2.3 and the following code no longer
works...
$templatetext = preg_replace("//e", "g_includecallback(\"\\1\")", $templatetext);
if (!preg_match("/([[:ascii:]]+?)([[:ascii:]]+?)([[:ascii:]]+?)$/i", $templatetext,
$matches))
{
// Report the error and stop processing the page
g_Halt("Could not find set definition in set list template:
$g_setlisttemplate");
}
The first line that processes includes works and after that line
$templatetext contains the full template with the include statements
replaced with the contents of the file. After the preg_match statement
has run (and succeeded), $matches[0] should contain the same as
$templatetext did after the previous line. However, this is not the
case. A sizable chunk of the text at the start of the variable has been
lost and I cannot figure out why. Can anyone give me any pointers?
Thanks.

So I think I am a reasonably clever programmer and I have now done enough web programming that I understand the cookie mechanism. What I can't figure out is why so many people are paranoid about cookies. I don't really see much of anything that can be done with cookies to invade someones privacy. Am I missing something here? Exactly. The problem isn't the mechanism, it's the implementation by the programmer. If you save my favorite color in a cookie, no big deal. If you save my username and password in a cookie, that is a big deal. Cookies are sent back and forth between the web server and client in plain text, so it can be captured. The other thing to realize is that cookies can be changed; they come from the client. So if you set my "id" to 555 in a cookie and that determines who I am for you site, I can change the "id" to 333 and become another person. Again, it's a problem with the implementation by the program, not cookies themselves. And don't forget the effect media hype had on their reputation. Cookies were portrayed as bad guys.

His case fell apart the moment he admitted that that was the reason he chose that domain name. I see now that he has settled with MS which is a shame because I think he should be made an example of. MS are only doing this to save their public face. As for the argument that he's only 17, what the hell does that matter? His motivation was clearly to cash in on either the similarity or the publicity from the action MS would take. The lucky fscker got the latter. -- Stuart -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

That line is not valid code. I'm guessing it's part of a comment that

As I understand it you're wanting to request a collection of videos from multiple user accounts in a single API call. PHP cannot help you if the API does not support doing that, so you need to direct the question at people who maintain and use the API. PHP can do a great many things, but it cannot remotely change the functionality of a third party API. -Stuart -- http://stut.net/ > On Jan 7, 2009, at 4:40 AM, Stuart wrote: > >> 2009/1/7 L.

Doing this is evil and should be avoided if at all possible. However,
assuming you really need to do it this way...
The best way to validate inclusion is to check the value of
$_SERVER['REMOTE_ADDR'] in the remote script and only allow known IPs.
This is not foolproof but will kill off casual attempts to get the
code.
Alternatively if you change the test for $safe_flag to
$_GET['safe_flag'] and add ?safe_flag=1 to the end of the URL in the
require call that should also work, but is easily copied. You could
randomise "safe_flag" and the value to make it more difficult, but
checking the IP is far better IMHO.

The first point to make is that the risk is no higher now than it has been for the previous 7 years. Register_globals is not inherently insecure, it's the way people code their scripts which makes it open to abuse. > to work again I have to spend a lot of hours to modify the code. boring job. > but, I'm more concern does client has to pay the changes/upgrade or it's > still "my obligation"? > anybody had similar experience? Personally I'd tell the client that the host has upgraded the server software which has broken the site. It needs work and they need to pay for it. If they object tell them you can work around the issue but it means potentially exposing the site to potentially fatal security risks. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If the remote side is returning the code rather than running it then
anyone can see exactly what to do to get it to work. There is no
security there.
OP: Does otherhost.com run the code or return it?

You can't have both method overloading and variable argument lists - they're just not compatible. You can simulate overloading by putting the common code into a private method and having several differently named public methods that all use the private method. Alternatively you can use variable arguments to get around it. Either way I definitely prefer support for variable and undefined arguments than overloading. >> Absolute rubbish!

That remaining 5% is the remaining 5% for you but you can't assume that for everyone else, and it's pretty arrogant for you to think you know what everyone wants. At the end of the day PHP is open source and if there are features you think will be welcomed by the whole community you can either suggest them on the internals list, develop them yourself and submit patches or pay/convince someone else to develop them and have them submit patches. Just don't be surprised when you discover that your "simple" enhancements have unexpected side effects that make them anything but simple, especially when you need to maintain BC as much as possible. Also, ignore Tony... PHP won't get better without people making suggestions, even if they turn out to be impractical or unpopular, so don't ever "LEAVE PHP ALONE"!! ;-) -Stuart -- http://stut.net/

But you've added an extra piece of information to every zval floating around the system - what type it is, if any. Huge amounts of code would need to be changed to check that value and deal with it in an appropriate way. Not a huge performance hit per variable but repeated across a large CMS or framework the effect could be pretty huge. I don't even pretend to know enough about the internals of PHP to determine stuff like that, but I've been coding long enough to recognise that everything code does takes time so the less you can have it do the better. >>> it's a simple need: if I can type that my variable can only contain an >>> int, >>> then I know it's always an int without tonnes of checks to check it >>> actually >>> contains an int / is getting set with an int throughout the rest of the >>> app >>> (especially when multiple dev's are working on it). >> >> I would argue that what you have is a want based on your current >> implementation strategy, rather than a "need".

Then your functions/methods should be checking their inputs in the same way you check the inputs from users. I recall a function I wrote a while ago which allowed the first line of each function and method did something like this... check_args(func_get_args(), 'error', 'int', 'string:30', 'int:5-100', 'bool'); First argument is the array of arguments. Second it what the function should do in the case of an incorrect argument - in this case to trigger a user error. Other options here were 'warning', 'notice', 'email:u...@domain.com' and true. Most of those should be self-explanatory, and if true is passed then an error message is returned. The rest of the arguments should be one per function argument stating what's allowed. The options here were numerous and I can't remember them all, but you get the idea. This single function made validating arguments for any function or method a doddle and extremely flexible. Could your static types validate the length of a string or ensure an integer it within a range? >> Any data coming from the user would need the same amount of validation >> regardless of whether you were stuffing it into untyped or typed >> variables.

Ahh, but you can't catch those inline so you have to build a generic handler. Let's take the example of a form handler. I have a script that grabs the data posted to the form which calls a method on a class to act on that data. With typed arguments you're forcing the validation to occur outside the method which is where it really ought to be done. This means it will likely need to be duplicated everywhere you need to call that method. Chances are you'll end up writing a non-typed method to handle that, so why not just do the validation in the actual method that's being called all over the place?!! You can ignore the need to validate on the basis that the typed arguments will catch any problems, but then you need to craft your error handler generically and create a very poor user experience. IMHO an exception would be a better choice, at least then I can deal with it in the correct place and maintain the flow of the script. However, I remember reading a while back that having the engine throw an exception into user space is less than simple, but I can't recall the details. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Without adequate investigation or comment from people who actually know about this stuff it's impossible to say whether the costs are too great to make them acceptable against the benefits. OO had a massive negative effect on performance, but it still happened because the benefits greatly outweighed the costs. IMHO all ideas should be properly considered, regardless of my gut reaction to them. >> As far as your "if I can do it why can't you" comment goes, I don't >> think anything has been said that would imply Nathan is not just as >> capable of developing complex systems as you think you are.

People rarely say they're superior, but that opinion often comes across in the way they interact with others. I don't care how long your career has been, there's a way to productively deal with other people. Coming back to the OO example, a lot of us got a lot done before that came along, but that didn't make it any less welcome when it arrived, and someone had to take the first step and suggest it. Attack people for making suggestions and you'll quickly lose a valuable source of ideas. I'm done with this now as you're clearly set in your ways and it's not adding value to the discussion.

It's a security feature to prevent SQL injection. AFAIK you'll have no
problems so long as all calls to mysql_query happen on the same DB
connection so you might want to start using the linkid parameter.

Depends what you mean by "maintenance". Will you be updating the site for them often? To be honest putting a fixed cost on a years worth of maintaining a website is next to impossible. What happens if visitor numbers explode - you're stuck maintaining a busy site for the cost of a much smaller site. IIWY I'd charge per update and an hourly fee for sysadmin work. Unless you feel like gambling that you'll get more with a fixed annual fee. But remember that it is a gamble. Either way make sure there's a written agreement that details exactly what's included in any fixed fee. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I bolded where the errors are happening. Holy crap on a cracker, I'm not gonna read all that. An undefined variable notice basically means you're trying to use a variable before it's been given a value, so look for that on and around the line it complains about and either display the variables or trace them back to confirm they contain what you think they do. The other error indicates that you're trying to use object notation (->) on a scalar (number, string or array). Again, look at the line it points you to and confirm the variables it contains have the values you think they should. This is basic debugging. Spending time resolving these errors yourself is time well spent, and the more you do it the easier it becomes. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It doesn't, but the end of the script performs an implicit flush.

1) I really wish people would look at other replies to a post before

2) CURL cannot perform a "header redirect" as the OP is asking for, so
the more useful response is to ask what they're actually trying to

The __set and __get magic methods allow you to arbitrarily create properties, and IMHO is the most flexible way to do it. If it "just worked" as you want it to you would not be able to create rules around what properties can be created or what values they can hold. I use those magic methods to implement validation in my model classes. If $this->x simply created x I would have to implement it using accessor functions which IMHO is much less intuitive. When deciding whether to call __set or __get PHP looks at whether you can access the property in the current context, so if you declare a private or protected property you should be able to set its value from within the class without involving the magic methods. Hope that makes things a bit clearer. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

"Our Web servers use Linux and Apache and PHP. Our database servers run MySQL. We use memcached to help keep the site snappy. Some of our behind-the-scenes software is written in Python and Perl and Java, and we use gcc and Boost for the parts that aren't." Based on everything I've read there is very very little non-scripted code behind Facebook. The performance of a web-based application rarely has anything to do with the language it's written in. System architecture, caching levels and DB indexes have a far more profound effect on the performance of an app than whether it's compiled or scripted. To the OP: Which DB server you use is far less important than making sure you're using it right and optimising it as much as possible. Sure there are differences between them, and MySQL is better in certain situations than Postgres but a badly configured and optimised Postgres instance will always outperform a well configured and optimised MySQL server. "Enterprise" doesn't mean anything. if you're going to ask for platform and software performance comparisons you need to provide a lot more detail about what you're building, what skills you have available and what kind of budget you're working to.

This is the way I would approach it. Once you've used an ID in a database you should never reuse it so long as there are references to it in other tables. If you need to exclude it from use you need a flag to indicate that. > In any event, what problems do you foresee if I used the actual names and > titles for the Course-to-Tutor table instead of their id's?

If you need to change any of the names, e.g. to fix a typo, it's potentially a massive update, whereas it's a change to a single row if you use IDs. Another thing to bear in mind is the size of your indexes. IDs are small, strings are not. Having said that it depends on the DB server as some are better at handling string indexes than others. Depending on exactly what your history requirements are it may be worth exploring other options to maintaining a history. One of the sites I work on maintains an audit log such that if something gets deleted that gets recorded in a semi-structured but fairly generic way so if I need to know when record x was deleted from table y and what record x contained I can craft a SQL query to get that from the audit log table, albeit fairly slowly. I also records inserts and updates to create a complete record. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Session data is stored on the server and tied to a browser using a cookie. The cookie contains a random string which uniquely identifies a session on the server. The session_start() function handles all the details of setting and maintaining that cookie and managing the server-side data. Cookies are transferred between client and server with every request in the headers. If you don't have Firefox getfirefox.com. The google for the livehttpheaders addon and install that. Turn it on and browse your site. You will see the cookies in the headers of both requests and responses. Cookies are not stored on the server side, they are sent by the client with each request. No additional HTTP requests are involved when using sessions. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Best place to do this is in the SQL query with a UNION.

Good advice. I would also advise against stripping and trimming

(e.g. Your Server makes \' out of '). If you have this option switched on on your server you really need to do everything you can to get rid of it. It's evil and has been completely removed from PHP 6.

Not sure what you mean by users pretending to know their password, but if I put a space at the start or end of my password I would expect that to add to its complexity and make it harder to guess.

I think people are like that everywhere, particularly above a certain level of management in my experience. I wish you luck in convincing them but I've found that PHP rarely wins when put up against the sales and marketing budgets available to Microsoft and Oracle.

C++ is a good option, but if OOP is the focus it might be better to use Java or similar where you don't need to worry so much about memory management. If you're dealing with people who know C then C++ will work well, otherwise not. The worst thing you can do is skip over the details of C++ development because you want to focus on OOP. You'll end up with a bunch of people who *think* they can code in C++ but really haven't got a clue. Personally I'd have preferred my university to use Smalltalk, but none of the professors knew it so I had to teach myself. It's the original and IMHO still the best implementation of OOP concepts around. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I suggest you look at memcached - it's an in-memory volatile cache that performs extremely well. APC has a similar feature but I've never used it. Also, are you guestimating the performance of DB queries against a serialised file? Do some tests and you might be surprised at how quickly PHP can unserialise data. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Drop the above line and I reckon it should work. The content you're
sending is not XML, it's form fields which CURL will default to. It
just happens that one of those fields is XML.

In that case you're not sending them what they're asking for. Are the
method, login and password fields supposed to be separate or should
they be included in the xml? At the moment they're separate so when
you tell the server it's in XML format you're lying because only part
of it is.
As a test try setting $postArgs = $xml. If I'm right it might either
work or give you and authentication error.

The original code you had, minus the Content-Type header will do
exactly that. Either the documentation is wrong or there's something
wrong with their system.
I suggest you create an HTML file containing a form with those fields
that posts to the destination URL, fill it in with valid values and
see what happens when you post that. Remove CURL from the equation,
and if that doesn't work go back to them and show them that form and
the response you get, because according to that documentation it
should work.

You need to specify the absolute URL for all assets when using a URL scheme like this because the browser has no idea that index.php indicates the current directory so it resolves relative paths using the full URL. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

So > it's not a reliable solution. This is your problem, you're not understanding where the paths are being resolved. Apache has absolutely no involvement in resolving relative paths in your HTML files to absolute URLs. The browser does this. All you need to do is use absolute URLs and everything will work fine. By absolute, in case you don't know, I mean starting with a / and being "from" the document root in the web server. For example, if you have a tag like arse and arse.php is in the same directory as index.php you need to change it to arse. Another example... if you have crack where crack.php is in the subdirectory somedir beneath where index.php is you need to change the tag to crack. You need to apply this to all URLs in your code, including stylesheets, images and javascript references. This should not be a difficult concept to grasp, so maybe I'm not explaining it right. If so please explain what you understand by what I'm saying and I can alter it to be more helpful. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If your development server has a different layout to your live server you're simply asking for trouble, especially since you're using a front controller pattern (as evidenced in another thread). It's simple to fix this. Add a hosts entry for mysite.local pointing at pokey's IP. Change the server software so it has a virtual host for mysite.local pointed at the mysite.com directory in the existing web rooot. This is not difficult and will allow you to solve both of the problems you are currently asking this list about. -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

A protocol in computer science is defined as "rules determining the format and transmission of data". CGI is a protocol defining the format and transmission of data between two entities, most commonly an HTTP server and an executable of some sort. It has no connection to TCP/IP, HTTP or networks in general. -Stuart -- http://stut.net/ > 2009/2/17 Stuart >> >> 2009/2/16 Thodoris : >> > In addition to this there is an API for C that can be used to code web >> > applications and it is known as CGI (it is provided by many languages) >> >> CGI is a protocol not an API and has no specific connection to C. >> >> -Stuart >> >> -- >> http://stut.net/ >> >> -- >> 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
