Maximum execution time of 30 seconds exceeded求助
PHP脚本随机碰到错误,PHP Fatal error: Maximum execution time of 30 seconds exceeded in C:\wwwroot\query.php on line 16
但这一行
include_once "common.php";
session_start();

extract($_POST); //=> 第16行
extract($_GET);
extract($_SESSION);

$_POST应该是空的,因为php是以get的方式被访问的。这个脚本会被5-10个左右的客户端,以大概1-2秒的频率访问。
这一般会是什么情况?
系统构架在win2003上,IIS + fastcgi

------解决方案--------------------
PHP Fatal error: Maximum execution time of 30 seconds
php 运行超时!
估计你的程序中有死循环
------解决方案--------------------

探讨

但楼上的哥们。。
include_once "common.php";
session_start();

extract($_POST); //=> 第16行
extract($_GET);
extract($_SESSION);

前面没做任何事啊。common.php都是一些函数,没有执行任何逻辑。
所以我奇怪的是为何,会在extract($_POST);这一行超时。。
