Description
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. If seconds is set to zero, no time limit is imposed. 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.
警告
set_time_limit() 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.
注: The set_time_limit() function and the configuration directive max_execution_time only affect the execution time of the script itself.

max_execution_time = 30
max_input_time = 60
$TimeLimit=60; /*设置超时限制时间
缺省时间为 30秒
设置为0时为不限时 */
@set_time_limit($TimeLimit);
当任务完成的时候@set_time_limit(30); //恢复缺省超时设置
不过当你的PHP打开safe mode（模式）的时候，这种方式是不可以修改的
全面加个@可以不会在页面显示错误，但这只是自欺欺人的做法
我的意思是说如果程序达到了time limit的时限,不出现错误信息,希望它继续执行下面的程序
set_time_limit谁不会用
若超过 PHP 程式执行时间则传回 true。语法: int connection_timeout(void);传回值: 整数函式种类: PHP 系统功能
内容说明
若 PHP 程式 (script) 执行时间超过设定值则传回 true。使用时不须输入参数。
