(PHP 3 <= 3.0.18, PHP 4 >= 4.0.0)
set_time_limit -- limit 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
configuration file. 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.
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 configuration file.
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(), the sleep() function, database queries, etc. is not included when
determining the maximum time that the script has been running.
