The use of PHP set_time_limit () function _php tips

Syntax: void set_time_limit (int seconds)

Note: set the number of seconds a program allows to execute, and if the time limit is reached, the program will return an error. Its preset limit time is 30 seconds, the value of max_execution_time is defined in the structure file (called Php3.ini in PHP3, PHP4 is called php.ini), and if the number of seconds is set to 0, there is no time limit.

When this function is called, set_time_limit () recalculates the maximum execution time from zero, that is, if the maximum execution time is a preset 30 seconds, and it takes 25 seconds to execute the program before calling the function Set_time_limit (20). The maximum execution time of the program will be 45 seconds.

Note: when PHP is executed in safe mode, Set_time_limit () will not have a result unless it is a time limit to turn off safe mode or modify the structure file (called Php3.ini in PHP3, called PHP.ini in PHP4).

Example:set_time_limit (1000)
