set_time_limit函数可以临时定义你当前页面的执行时间,set_time_limit(0)时页面就永远有效直到程序执行完毕了,下面我来介绍set_time_limit用法.
语法 : void set_time_limit (int seconds)
注意 : 当PHP是执行在安全模式时,set_time_limit( )将不会有结果,除非是关闭安全模式或是修改结构档案中(在PHP3中叫做php3.ini,在PHP4则叫做php.ini)的时间限制.
实例代码如下:
<?php set_time_limit(1000) ?>
当此函数被调用时, set_time_limit()会从零开始重新启动超时计数器.换句话说,如果超时默认是30秒,在脚本运行了了25秒时调用 set_time_limit(20),那么,脚本在超时之前可运行总时间为45秒.
实例代码如下:
<?php
require_once('db.php');
$stmt = $db->query($sql);
while ($row = $stmt->fetchRow()) {
set_time_limit(0);
// your code here
}
