php提示Notice: Undefined index 错误解决办法
这种问题是你php中把错误提示开启了之后,会把你编程的一些错误给告诉你,下面我来给大家分析php Notice: Undefined index 错误提示方法,有需要的朋友可参考。
原因分析
出现这种问题一般是变量未定义造成的
例
代码如下 | 复制代码 |
if($a) } |
//提示:Notice: Undefined variable: a in E:/www/test.php on line 5
代码如下 | 复制代码 |
$a=1; } //输出1 error_reporting(0); if($a) } |
解决方法总结
1、如果是变量未申请直接申名变量如 $a=1; 这样。
2、在文章头部加error_reporting(0); 所有错误都不提示
3、isset($_GET["page"]) 或 :@$page=$_GET["page"]
4、用php.ini中error_reporting = E_ALL & ~E_NOTICE 可以关闭notice的显示,屏蔽掉此类警告好,
