What does your code look like?
I just realized that when called a second time, set_error_handler()
returns my custom error handler but it is never triggered.
Code looks like this:
?php
if (set_error_handler('core_error_handler', E_ALL) === NULL)
echo 'could not set error handlerbr /';
trigger_error('test error');
var_dump(set_error_handler('core_error_handler', E_ALL));
function core_error_handler($errno, $errstr, $errfile, $errline)
{
echo 'error...';
}
?
This gives me the following output:
could not set error handler
Notice: test error in /var/www/.../core.inc.php on line 5
core_error_handler
Have you thought about the fact that you're pointing to a function
that's not been defined yet when the error is triggered?
And set_error_handler() returns NULL because there isn't a previously
defined error handler, not because it failed.
Hope this helps.

You're missing the $ for ret_val on the return line.
PHP thus understands the return value as a string,
ret_val, which would be taken as 0. Since all elements
are now equal, the order of the elements in the array
is undefined.

Actually, PHP first looks for a constant named ret_val, then it uses a
string containing ret_val. So, if there was a constant with that name,
that value would have been used.

Re: [PHP] Sanity checker?
Ezra Nugroho escribió: Well, Since my original post failed to generate reasonable feedback, not even a successful kick at people's funny bone or a flame, let me restate my question with a story. Php reduces the barrier to web development quite a bit, such that less technical people can jump in really easily. In one side, this is great because it helps the adoption of the language, and more people get to create their dynamic websites. The flip to it is that many non-technical people write low quality php code, which in turn make their code vulnerable and not scalable. I envision a tool that would audit your php code, and tell you if your code is good or not, if it has scaling issues, etc, etc. Basically it tells if your php code is sane or not. I have a few ideas of how a sane php code should look like, but I certainly don't know everything. That's the reasons behind my earlier questions. Basically I am looking for things to check in codes that pose high running time risks. Or even simpler, I am looking for best practices, advices, guidelines that you would give to new php developers. So here are the questions again: Does anyone know of any tools to test the sanity of your php code? If you were to check the sanity of your code, what would you look for? Any pointers for other resources? Thank you Ezra That's something PCs are still not able to do. We still have a long way to go before algorithms can simulate consciousness to the level they can judge the sanity of a code. For the time being, auditors will have to be humans, although they use some tools to make that task easier, mostly predefined searches with regular expressions to find common mistakes and possible security holes and malicious code. Where I worked some years ago they run your code through some awk scripts and shell scripts automatically on everything send to production, and after that, they auditioned the code in the old fashion. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Matt Todd wrote: There's nothing wrong with staying true to the philosophy at all, I just think that it may well be detrimental in the end. And that is what I said in the (toilet)paper, that there will be (emphasis on the eventuality, not on the present actuality) a time that PHP will become the old stuff because it did not evolve with the philosophies. It's true that a language that doesn't evolve with the market will die, but still you can expect us to follow any new trend because they believe it's the way to salvation. Try to think first if the new philosophies can be properly applied to this market, if they can bring a proper solution to our problems (if not they will become a new problem and we don't want that). Anyway, programming languages have proved to live longer that one could ever expect. Before attending to PHP's funeral, I'm pretty sure we'll be burying another die harder language, like the C language, in a very emotional ceremony (I can almost see it, someone will cry loudly: I'll miss using your precompiler macros!). These philosophies are new and I can understand thinking that it's hype, but it's important to recognize it as legitimate. Agile Development (and the broader term Web 2.0) is, right now, the bleeding edge of development, and I and many others see it as the future of development philosophies. Don't say it's good, prove it! All I can see in Web 2.0 is those guys are making more money than us, let's copy them! Those guys are exploring uncharted area in web development and they're more worried in making their software work rather than worrying if the philosophy is appropiate or not. Still, marketing rules say no mather how unappropiate your company's philosophy is, it's the best. Of course they will say Web 2.0 is the best, is what they're doing and they don't want anyone to think they aren't giving the clients the best there is. And now we have to deal with even crazier request from our clients, like making an AJAX application in a week that supports all imaginable browsers in the market. They really believe that AJAX is a fucking walk in the park! AJAX is a fricking cocktail of death! Bring out the spaghetti code and let us feast on an eternal reengeneering cycle! I'm not saying that Rasmus can't see, but that he will easily choose to stay with how he sees the forest – understandable as I choose to stay with what I see, but I think he has a lot invested in his view and may not open up as easily. Stop blaming the poor guy! He only made a tool he needed and was kind enough to share it with the world. If you want to blame someone for what direction PHP has taken, blame us! That's the whole point of PHP being open source, isn't it? All the current problems in PHP are directly or indirectly caused by whining developers and their extravagant requests. Magic quotes are bad? Well, teach those bastards to properly quote their sql's strings! You think that currently PHP is being lead to unavoidable doom? By all means, be my guest and make PHP++, for all I care. The code it's there. To Stut: Honestly, I'd love to see basic variables be objects, as models of real world data with properties for the data such as a $number-length or $word-as_array() giving you letters. Have you stop to think what the efficiency cost would be to make everything an object? We're already suffering much to avoid the waiting 2.5 second it's way too much cutline (they say we can't do real time applications) and you want to keep adding functionality that will deteriorate this? I love the way basic types are handled by PHP, I specially love PHP arrays, if you touch them, I fucking kill you! I know that PHP is a functional language, and secondly, an OO language, but I think that you can blend these things better and have the OO brought to the forefront a bit more. Yes, I'm a fan of OO, but I know that many people aren't and don't use PHP's OO (and don't when it's appropriate). But I know you can integrate OO without having to force the functional programmers to give up their way. Have you been attending to your CS lessons? PHP is an *IMPERATIVE* language, and secondly, that the language provides OOP features doesn't make it an OO language. Maybe you have chosen your language wrongly, you should try JSP or any other Java based web server technology. PS: I think you have the terms wrong. What you're calling functional programming may be what is usually known as procedural programming. This is just ONE thing that could make PHP better and allow for more modern philosophical development. Particularly, I would like to see more creativity. Sure, PHP's moving fast, but with our big things being Unicode support and removing globals and safe mode, I think that we could be a little more innovative for PHP6. Again, it's not behind the times right now, but the times are changing and I'd like to see PHP change with them. M.T. I won't deny times are
Re: [PHP] session
It's really that hard to read the whole manual page about session_destroy()? Quoting the php manual: In order to kill the session altogether, like to log the user out, the session id must also be unset. If a cookie is used to propagate the session id (default behavior), then the session cookie must be deleted. setcookie() may be used for that. In other words session_destroy() is not enough to kill a session. PS: I just checked the portuguese version of the manual, it seems to be outdated (I don't know portuguese but from the examples given and some deductive reasoning I'm sure it's either a translation of an old version of the manual or a bad translation). If you understand english, rely on the english version. João Cândido de Souza Neto wrote: Hi everyone. I hope someone here can help me.

Re: [PHP] session_destroy
It doesn't matter, PHP decides automatically which is the best method to
make a session persist. If it founds that the client allows cookies,
cookies are used. If such method is not available, the session id is
writen to every url through an output buffer with an url rewriting
filter. There was another method before using the url rewriting but I
forgot, check the manual.

Re: [PHP] programming contests as a way of finding/evaluating offshore talent...
This is just my personal opinion on the subject. I don't believe nowadays programming contests are of any worth when judging a developer's talent, at least not what I expect from a coder. These contests usually prove that an a coder can pull out an development as an individual, but from looking at the code, and the way they code, I realize that they aren't fit for an enviroment where working as a team is a must, at least that's the kind of coding I don't want to see in a project where I could be working. I haven't seen yet a contest where code which is written in a readable and understandable way earns more points. If a coder does his job faster than others but he's the only one who can understand the code, we'll have a problem when the client requires a new feature and he's not longer on our team. I would choose the one who takes his time but thinks carefully ahead and takes into account who will be using the code he's writting. If he is also good with documentation I'll even handcuff him to his desk and do anything to keep him in the team. bruce wrote: hi.. i'm looking for opinions on the worth of programming contests as a way of judging the talent of potential software developers... any thoughts/pros/cons would be appreciated.. and yeah.. i know this is a little off topic.. but some of us here deal with these issues.. if you know of a better email list for this kind of question, let me know, and i'll move it to there.. thanks in advance! -bruce -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] function by reference
Well, it was a bad example to begin with, first of all max() is already
defined in php, I should at least checked that before posting. Second, I
forgot PHP (the Zend engine) has an interesting way of handling
variables, when you copy assign a var or pass it as an argument of a
function, a real copy is not made but a reference. When you modify the
reference, an actual copy is made before the modification. What's
happening with the function you posted is that the variables are not
passed by copy but by reference, that's why it works. Anyway, this is
due to conditions on the way PHP (the Zend engine) handles its internal,
you shouldn't rely on this in your code.

The ampersand before the function name indicates that the function

$global1 = 10;
$global2 = 9;
$maxglobal = max($global1, $global2);

echo $global1;
//this will print 11 since $maxglobal is a reference to $global1

It's going to hurt thinking about that. :-)
But that produces the same results as:
?php
function max($var1, $var2) {
if ($var1 $var2) return $var1;
else return $var2;
}
$global1 = 10;
$global2 = 9;
$maxglobal = max($global1, $global2);
$maxglobal++;
echo $global1;
//this will print 11 since $maxglobal is a reference to $global1

Note the absence ampersands in the function, but an ampersand remains
in the assignment:

Re: [PHP] simpleXML - simplexml_load_file() timeout?
Maybe it's too late to say this, but if your real problem is that you
don't want the function reading
the rss feed to block the rest of your page, you can always put the
output of the reading of the feed
on a separate page, and include this through an iframe.

Hello all,
My website uses simpleXML to print the headlines from a few different RSS
feeds. The problem is that sometimes the remote feed is unavailable if there
are problems with the remote site, and the result is that I must wait for 30
seconds or so until the HTTP timeout occurs, delaying the rendering of my
site.
So far, I have moved the code that grabs the RSS feeds to the bottom of my
page, so that the main page content is rendered first, but this is only a
partial solution.
Is there a way to give the simplexml_load_file() a 5 second timeout before
giving up and moving on?
Here is my function:
function getFeed($remote) {
if (!$xml = simplexml_load_file($remote)) {
print Feed unavailable;
return;
}
print ul\n;
