Title: Function Time Limit
Post by: nend on May 29th, 2012, 06:11 AM: I was wondering is there any way in PHP to set a time limit on a PHP function. Say if the function is not done in a certain amount of time the function execution is cancelled and the function returns nothing.

What I want to do is start a heavy query and if the query doesn't finish in a certain amount of time have the query stop and the function exited.

That said, the MySQLi driver (note, not the ext/mysql driver that SMF and Wedge rely on) can actually set a timeout with the mysqli_options() function but you can't intermix them.

That might be enough reason to convince us to move to ext/mysqli though!

Post by: Arantor on June 3rd, 2012, 10:57 PM: I said *might*. It's not really a *huge* change from my perspective, MySQLi can be used mostly as a drop-in replacement over MySQL's original driver, but I'm not sure how widely deployed MySQLi is.
