Re: [PHP] set_time_limit() in a loop
Matthew, There's some strange stuff going on here, and in the conversation. For information about set_time_limit() please read http://uk2.php.net/manual/en/function.set-time-limit.php. Despite the sense of what is written below, the manual says When called, set_time_limit() restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out. Accordingly, every loop of the script is asking for the time_limit to be imposed in 30 minutes' time. The foibles of mail() are well documented on this list - please check the archives. The most pertinent comment being that mail() does not suit volume transmissions, and bulk-mailer software should be used instead. In your case, personalisation makes that a little more difficult. Do you have any idea how far through the mail out is the script getting before it stops/stalls/bombs/cycles aimlessly? If not, why not? The previous respondent asked you for the exit criteria for your while loop. The code example below is not pure PHP. Again: what is it - show us the code. Are you suffering this problem on a production machine, but not on your development machine, ie do we have machine-differences to take into account? Have you tried commenting out the mail() command and replacing it with an ECHO To address (and perhaps a counter) to see just how far the script gets? If that works perfectly, then questions have to be asked about mail() and the email server being used... at the moment all the questions center on what you are ACTUALLY doing. Please advise, =dn Thanks for your reply Paul. The script is getting subscriber details from a database and then firing our personalised emails in HTML and text format. The while statement loops through the query results and fires out the emails using the mail() command. It works well so far and indeed does finish the loop OK - but as mentioned the script is still running 13 hours later. I don't get it. Any ideas? Is it possible to kill a script via PHP code?

what are you doing a while on if while never ends and you reset the time out each loop and use ignore_user_abort(true), it will still be going 13 hours latter. maybe if you send the full code so we can look at it.

your first thought was correct - it sets it to 1800, it's NOT accumulative. it would have something to do with ignore_user_abort(true); and also is your while loop's exit check working?

Thanks for your reply Martin.

RE: [PHP] set_time_limit() in a loop
no, that shouldn't affect it - ignore_user_abort() keeps the script going even if the user aborts (I'm assuming you already knew that...) so the only thing that I can think of that's keeping the script going it the while loop - check the exit condition to make sure it does actually end...
