屏蔽PHP默认设置中的Notice警告的方法,默认设置notice
PHP的默认设置是显示Notice警告提示,这会造成页面无法正常显示出来。你有没定义的变量直接使用了。不过编PHP的时候本来就不像C++那么严格,编程的时候经常还会利用这个特点。
在把自己辛辛苦苦编写的PHP程序部署到服务器上的时候,相信这样的提示很多人都见过:
PHP Notice: Undefined variable PHP Notice: Undefined index
看看吧,你有没定义的变量直接使用了。不过编PHP的时候本来就不像C++那么严格,编程的时候经常还会利用这个特点。PHP的默认设置是显示这些提示,这会造成页面无法正常显示出来。
//error_reporting(E_ALL); error_reporting(E_ALL || ~E_NOTICE); //显示除去 E_NOTICE 之外的所有错误信息
第一个是代表显示所有错误,
第二个代表显示所有错误不显示警告,
我们只要把第二行前面加//,把第一行前面的//去掉即可。
附:各个错误报告详解
使用方法:
error_reporting(0);//禁用错误报告 error_reporting(E_ALL ^ E_NOTICE);//显示除去 E_NOTICE 之外的所有错误信息 error_reporting(E_ALL^E_WARNING^E_NOTICE);//显示除去E_WARNING E_NOTICE 之外的所有错误信息 error_reporting(E_ERROR | E_WARNING | E_PARSE);//显示运行时错误,与error_reporting(E_ALL ^ E_NOTICE);效果相同。 error_reporting(E_ALL);//显示所有错误
