PHP Functions

Function: set_time_limit

(PHP 3, PHP 4, PHP 5)

set_time_limit -- Limits the maximum execution time

Description

void set_time_limit ( int seconds )

Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. The default limit is 30 seconds or, if it exists, the max_execution_time value defined in the php.ini . If seconds is set to zero, no time limit is imposed.

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.

Warning

set_time_limit() has no effect when PHP is running in safe mode . There is no workaround other than turning off safe mode or changing the time limit in the php.ini .

Note: The set_time_limit() function and the configuration directive max_execution_time only affect the execution time of the script itself. Any time spent on activity that happens outside the execution of the script such as system calls using system() , stream operations, database queries, etc. is not included when determining the maximum time that the script has been running.
