Re: [PHP] Script timeout?
set_time_limit() This function has no effect in safe mode, you will need another workaround, for example send fisrt 400 emails and redirect the browser to send next 400 emails and so on untill you are done.

Re: [PHP] Script timeout?
I'm running PHP 5.0 beta 3, and I have seen script timeout errors before. It's just odd that I wasn't receiving them this time. Increasing the timeout helped, but didn't fully correct the problem. I just kept changing the SQL statement to WHERE user_key = [id number where it left off] so that it would send in batches and not send to the same people twice. I didn't code this originally or I would've used a SQL JOIN to combine two tables of data instead of hitting the database a second time for each record encountered as my other programmer did. So, I'm going to revise the scripts for future use and then do as someone said and save all the e-mail addresses to an array (and perhaps even free the result set) before sending.

RE: [PHP] Script timeout?
Two ways we deal with long running scripts like this are: 1) Run it from the command line. Usually, PHP drives web pages... But it can be used as a scripting language just like perl. Beginning the script with set_time_limit(0) kills the timeout. Also, running from the command line gets around all the weird browser display issues that one sometimes sees. 2) Mark your place as you go. Maybe include a field called something like lastSent. When each email goes out, mark it. That way, you can recover it later if something happens. -- jon --- jon roig web developer email: [EMAIL PROTECTED] phone: 888.230.7557 -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 27, 2004 7:36 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] Script timeout?

Try outputting something from time to time. Can anybody point me to information on all the possible HTTP timeouts there are (Apache, browser, ???), or care to discuss it here? We occasionally see timeouts that are not due to PHP, and I'm wondering where they are coming from.

Re: [PHP] Script timeout with set_time_limit(0);
Try setting the timeout to some high setting, beyond how long you need it to
run.
Often PHP just won't run for a really long time, for reasons I don't know.
It just occassionally decides it's done, but I know it can go for longer
than 3 days (phpIRC often lives that long and longer) so that probably isn't
your problem.
Try the function that gets how long your timeout is set to (can't recall the
name atm) before and after you set it and see what it says.
