#45264 [Opn->Bgs]: set_time_limit affects max_execution_time

ID: 45264 Updated by: derick@php.net Reported By: jdm at visi dot com -Status: Open +Status: Bogus Bug Type: Unknown/Other Function Operating System: Windows PHP Version: 5.2.6 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is correct, if you change it to something else, it should do that. The reason for this is that for some installations the default is unlimited, and you might want to protect parts of your app for running over time. Previous Comments: ------------------------------------------------------------------------ [2008-06-13 16:44:51] jdm at visi dot com Description: ------------ Calling set_time_limit appears to not function as it is documented. Per the documentation: 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. According to my test code, it is actually affecting the ini value of max_execution_time. As a result if the time limit is a smaller value, max_execution_time is altered to a smaller value, and script execution time can be cut short. I tracked this result down through drupal with the gallery2 integration module included where it makes calls to set_time_limit(30), which causes the module administration page to be cut short, even though my max_execution_time is defined to be 300 seconds. In my environment, the included code produces the following output: 300 30 Reproduce code: --------------- print '<p>'.ini_get('max_execution_time').'</p>'; set_time_limit(30); print '<p>'.ini_get('max_execution_time').'</p>'; Expected result: ---------------- I would expect the max_execution_time to either not change or be extended by the amount set in set_time_limit, according to the documented operation of it. i.e., the resulting code should produce either: 300 300 or: 300 330 Actual result: -------------- The resulting code produces this output: 300 30 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45264&edit=1
