set_time_limit — Set the maximum execution time of the script

Description

set_time_limit ( int $seconds ) : bool

Set the time allowed for the script to run, in seconds. If this setting is exceeded, the script returns a fatal error. The default value is 30 seconds, or the value defined in max_execution_time in php.ini, if this value exists.

When this function is called, set_time_limit() will restart the timeout counter from zero. In other words, if the default timeout is 30 seconds and set_time_limit(20) is called when the script has been running for 25 seconds, then the total time the script can run before timing out is 45 seconds.

Parameters

seconds

Maximum execution time, in seconds. If set to 0 (zero), there is no time limit.

Return value

Returns true on success and false on failure.

Comments

Note:

The set_time_limit() function and the configuration directive max_execution_time only affect the execution time of the script itself. The maximum time for any script execution that occurs such as system calls using system(), stream operations, database operations, etc. is not included when the script is already running. In Windows, where measured times are real-valued, this is not the case.
