PHP5中文手册·Limits the maximum execution time -- 追寻梦想＞编程乐园＞PHP 编程

说明

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 php.ini.

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.

参数

seconds: The maximum execution time, in seconds. If set to zero, no time limit is imposed.

返回值

无返回值。

注释

Warning

This function has no effect when PHP is running in 安全模式. There is no workaround other than turning off safe mode or changing the time limit in the php.ini.

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(), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running.
