在php开发时可能会碰到如PHP Notice: undefined index这种错误提示,如 $_GET['aa']; 就会出现PHP Notice: undefined index "aa"了。

下面我来总结出现PHP Notice: undefined index 解决办法。

1、php.ini配置文件,error_reporting = E_ALL & ~E_NOTICE

2、加个isset函数 isset($_GET["page"]) if-else判断

还有一个办法就是自定一个函数,这样就直接使用函数操作,代码如下:

function _get($str){ 
	$val = !emptyempty($_GET[$str]) ? $_GET[$str] : null; 
	return $val; 
}
Copy after login

调用方法:_get('str') 代替 $_GET['str'] 即可.
