When this function is called, set_time_limit() will restart the calculation of the maximum execution time from zero. That is to say, if the maximum execution time is the default 30 seconds, and this function is called It has taken 25 seconds to execute the program before set_time_limit(20), so the maximum execution time of the program will be 45 seconds.
Note: When PHP is running in safe mode, set_time_limit() will have no results unless safe mode is turned off or the structure file is modified ( It is called php3.ini in PHP3 and php.ini in PHP4) time limit.
