php session_start的问题
在php中,偶尔会遇到“Fatal error: Maximum execution time of 30 seconds exceeded in D:\website\controller\control.base.php on line 170”的错误,这一行是session_start。速度慢的时候这个错误经常错线,并且页面卡死耍新问题。
------解决方案--------------------
PHP.ini中找到
max_execution_time = 30 ;//设置成你想要的值,单位是秒
(也可以直接设置成不限时:max_execution_time = 0)
------解决方案--------------------
貌似也跟服务器内存有关系
------解决方案--------------------
session_start执行这么长时间很有问题,session理论上读个文件不会这么慢的,是不是被重载过访问数据库了?
------解决方案--------------------
1、你的问题应该是调试期间,访问的载体是同一浏览器窗口的不同选项卡。再次情况下,各选项卡共一个cookie。前面的未结束,后面的只用等待
2、直到 170 行才 session_start,显然你的程序存在严重的问题
------解决方案--------------------
服务器配置的问题,单个脚本运行时间最大值为30秒,请修改PHP.ini中找到
max_execution_time = 30 ;//设置成你想要的值,单位是秒
注:(也可以直接设置成不限时:max_execution_time = 0)这种不太安全
------解决方案--------------------
“Fatal error: Maximum execution time of 30 seconds exceeded in D:\website\controller是指这个脚本运行超出最大运行时间30秒,解决方法两种:
第一种:由于你的程序写的错误,如死循环等等
解决:检查代码
第二种:程序需要,代码正确,如大文件上传导致的
解决:修改PHP.ini中找到
max_execution_time = 30 ;//设置成你想要的值,单位是秒
(也可以直接设置成不限时:max_execution_time = 0) //建议不能设置0,这种不安全

可以使用auto session的。这样就不用每次写那个语句了。
