Well, according to the manual, you need to be using the FALSE parameter anyway
since "By default it will replace, but if you pass in FALSE as the second
argument you can force multiple headers". So the wrong behaviour is on the
(older) OS X server, but I'm as confused as you as to why this should be as
there is no indication in the manual or the ChangeLog that the default
behaviour has changed at any point.
Cheers!

RE: [PHP] caching problem
If the issue is a caching proxy or browser caching I suggest you look into
controlling the page caching header.
You can expire the header.
// calc an offset of 24 hours
$offset = 3600 * 24;
// calc the string in GMT not localtime and add the offset
$expire = "Expires: " . gmdate("D, d M Y H:i:s", time() + $offset) . " GMT";
//output the HTTP header
Header($expire);
Just a thought.

Since restarting Apache does not help, the problem is obviously outside the web
server. There are two possibilities I can think of...
* Browser caching
* Proxy caching
See if clearing your browser cache helps. If not then you probably have a proxy
between you and the server that's caching the content.

RE: [PHP] caching problem
Faith, I actually did read from the beginning of the message. That does not make sense. PHP files are cached intentionally, the system does not Cache PHP on its own. Sounds to me like you have an issue re-declaring an object or calling the right script/path/class/method something. I have never heard of PHP being cached unless it was intentionally cached it. Thank god for security reason! HTML output?? Sure all the time helps the browser load the content faster. I have a real issue with who ever told you that PHP is being cached, because if that was the case there is SERIOUS security hole in your PHP. I am doubting that. I have cached PHP, it can be done. Are you using APC(Alternative PHP Cache)??? I would not suggest it with complex scripting using classes and methods they are the whole reason NOT to cache. That’s just my opinion. Richard L.

What browser are you using? Certain older browsers such as IE6 have their own ideas about whether pages should be cached or not. You can usually bypass the browser cache by holding control and/or shift while clicking on the refresh button. Try that next time this happens. Other possibilities include filesystem issues, such that the OS is not seeing that the file has been changed - there are levels of caching on modern operating systems that most people, quite correctly, are not aware of. The likelihood of this being the cause is miniscule. If you're absolutely certain that you are not using any opcode caching (you mentioned that you are using pre-compiled binaries, and it's possible they include APC or similar by default), then I have no idea what's going on beyond what I and others have already suggested. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/

Fatih, I am sorry spell check auto corrected your name, I was not changing your name on purpose. It was not my intension to piss you off. I understand your frustration, trust me. I am running 5.3.6 on Windows Server 2008 R2 IIS, I am running massive class based methods in my own framework. I am trying to help you narrow down the issue. I never blame PHP first because in my trouble shooting steps, I never get to PHP before I find the issue. Segmentation Faults: that prevent the php script from completing locking up resources and causing a nightmare chain of events. It dumps the process at the fail point can look like it is a PHP thing but it is not. This can explain sometimes it works and sometimes it does not. This can be caused by a host of reasons: Buffer Overflow, Attempting to access memory the program does not own.

Re: [PHP] caching problem
OP: Can we see the methods in question? Have you tried running the code on a different server/host? Have you added any scaffolding to your methods in order to test your caching theory? This would be the first thing I would try (i.e. create random number (or whatever), concat with variable vals generated via method, other.)

Those browsers should be fine, but forcing a reload (the control/shift +
refresh) is always worth trying.
Maybe I should compile php myself disabling things i dont need and see it

You can see what's in your PHP build by creating a script that just contains
the following..
Run that and check the output. If you got the binary from php.net then
chances are that you don't have any opcode caching modules in there.
It's also worth doing a variation on Micky's suggestion - when I want to
make sure a script has actually been executed rather than cached data being
served I put a call to echo date('r'); in an appropriate place. That way the
script output will display the current date and time which should change
with each request.

You can perform the long-running job in the same process that handles the
request by sending appropriate headers. We use this to run reports that take
ten minutes without making the user keep the browser tab open. Call this
method before starting the job:
/**
* Effectively causes PHP to keep running after flushing everything and
closing the client connection
*
* @param mixed $status JSON-encoded and sent to the client
*/
public function flushAndCloseConnection($status) {
// disable any apache or php gzipping
if (function_exists('apache_setenv')) {
apache_setenv('no-gzip', 1);
}
ini_set('zlib.output_compression', 0);
// Tell the server and client we intend for it to disconnect
ignore_user_abort(true);
// Tell the client we are done!
header('Connection: close');
header('Content-type: application/json');
$json = json_encode($status);
header('Content-Length: ' . strlen($json));
echo $json;
flush();
}
In our case we send a JSON status string ("ok") as well.
Another option is to fork the process using pcntl_fork() [1]. I haven't used
this in PHP before so I can't give an example.
Peace,

While this will work, I would caution against doing this, especially when
using Apache as the web server. Keeping an HTTP request handler process
occupied with an offline task is a substantial waste of resources. Far
better to offload that work to a separate process so as to free up the
request handler so it's available to handle another incoming request.
Another option is to fork the process using pcntl_fork() [1]. I haven't used

Forking an HTTP request handler can lead to some very unwelcome
side-effects. I'd urge you not to do this. It may appear to work for a
while, but I guarantee you'll live to regret it.

[PHP] best ways to recruit volunteers for a PHP framework
Hi everybody, I have developed an ORM framework in PHP for the last 2 years and it's becoming a more professional and nice solution so before doing a new complete revamp I am going to look for volunteer developers to do a real good version. But I am wondering what would be the best and clearest way to present the project in order to get some people interested in it ? I was thinking about - showing the previous versions - showing use cases - showing unit testing (I'm doing test driven development) - a short user manual (the project doesn't have any user manual yet!) Thanks in advance!

thanks, I should have said I have the project already in sourceforge so I have an SVN ready, and a outdated website with an outdated user manual and even an outdated dissertation about the reason for the development of the project.

Build something they want to use, put a mechanism in place for them to contribute patches and new features, and let it happen naturally. You can't force developers to contribute to your project without paying them. As Jay mentioned, GitHub is a great place to share code, and it would appear to be far more popular than Sourceforge these days. It has features that allow other developers to fork your code and contribute changes back to your repository. However, it doesn't really matter where you put it because most of the interest in it will come from other things you do to spread the word. Contribute to PHP mailing lists and put a link to your project in your signature. Do the same on forums and any other channels where you can engage with your intended audience, but don't force it down their throats. Give your project lots of exposure, but don't ask developers to contribute - let them discover/decide how worthy your project is of their attention and efforts on their own. That's the only way to build a quality bunch of contributors. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/

Thank you, Negative Nancy. :) Those are excellent points, and luckily we're doing this for an infrequently run internal report that runs on a machine that doesn't do much else. Alternatively, you can use & in bash or some other shell to spawn a background job, and I suppose you could create a wrapper shell script that does that calls php in the background. But there must be a direct way using an alternate to exec(). David
[PHP] Connection usign SSL with a JAVA Server
Hi, i made a SSL Client using JAVA, with a key generated by Keytool. The command was the next: *keytool -genkey -keystore mySrvKeystore -keyalg RSA* Password: 123456 Now, im tryint to send a simple text using this kind of connection in PHP. The server already works with a Java Server / Java Client. Now i want a PHP Client. I tried every example listed in the OpenSSL section in the PHP help but nothing worked. Can you help me? Mariano
