I've got a script which uses cURL to connect to another website, and it seems to be getting stuck (I can't quite figure out how, but that's besides the point!). The trouble is that when my script runs it redirects you to a "please wait" page, and it then executes by itself. So you can't click 'stop' in your browser to terminate the script. If the script gets a fatal error, then the 'results' page will display an error saying that the script failed. If the script finishes successfully then obviously the 'results' page will have the results on it.
But my script appears to get stuck, and just never produces a results page, and never produces an error. So it must still be executing. The script wouldn't necessarily time out because time spent doing cURL connections doesn't count towards the script's execution time. And despite my cURL settings, cURL doesn't seem to timeout either. So my script is stuck in eternal limbo, which worries me because I've now probably got several scripts all running forever on my webserver! (Deleting the php file doesn't help, because php appears to store it in ram in order to execute it, so it keeps running even after you've deleted it.)
So to get to the point.....
How can I get php to terminate everything its doing (i.e. all scripts that its running) without shutting down the webserver? I can't shut down the web server because it's on a paid hosting thing, and I don't have that kind of access to it (only cpanel).
What are 'cron jobs'? Could I create one that resets php?

Check out this link to know about cronjob.
Set timeouts (CURLOPT_CONNECTTIMEOUT and CURLOPT_TIMEOUT) for cURL using curl_setopt.
Yeah, I'm already using CURLOPT_TIMEOUT, CURLOPT_CONNECTTIMEOUT , CURLOPT_LOWSPEEDLIMIT, and CURLOPT_LOWSPEED_TIME. Which is why I can't understand why it's getting stuck.
I'll have a read about cronjobs

Not necessarily. Take a look at the top post in this forum, it will tell you how to ensure that you receive all error messages for properly debugging php scripts.
It appears that my scripts are not getting stuck at all! Quite the opposite...they are failing...silently!
The curl_multi_select() function causes php to fail, without outputting any error message. I've submitted a bug on the php.net site.

Hrm, could you post a simple test case for us to try out?
I'll have more of an investiagtion today, and see if I can post some example code.
The problem is that I'm using the function in a script which is included in another script which is included in another script, and sometimes when the script is included it works and sometimes when it's included it just fails, silently. I can't figure out what makes it fail, but it definitely shouldn't just fail silently.
Here's my bug:
http://bugs.php.net/bug.php?id=42020
Hmm... Code looks really disorganized to me and there aren't as many {} as there should be, a while statement was ended with a ; . Yeah... that code = :S
Needs to be dubugged.

Trust me, the code works. And anyway, if it didn't then php would give an error message, not just self destruct! The strange thing is that the problem never occurs on my own server (Mac OSX) but it does on my webhost's, despite them both having the same php version. I'm going to start a new discussion to get some help with disabling the optimizers etc to see if they are causing the problem.

Any hopes of us getting a simple test case to demonstrate the bug?
