(PH3, PHP4)

Set_time_limit---&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Limit Maximum execution time

Syntax: void set_time_limit (int seconds)

Description:

Sets the number of seconds a program allows to execute, and if the time limit is reached, the program returns an error. Its preset limit time is 30 seconds, max_execution_time values are 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 longest 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 this 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 for turning off safe mode or modifying the structure file (called Php3.ini in PHP3, called PHP.ini in PHP4).
