最近在写php的过程中发现php提示php notice：………………的字样，虽然这个只是php的提示内容，并没有什么大的影响，但是出于安全性和美观方面的考虑，小弟还是想把这个东西去掉。

那么，怎么办呢？

抬出baidu，直接复制、粘贴php notice：，这样搜索的结果，一般有两种情况：

一、直接来一句：error_reporting=E_ALL&~E_NOTICE，搞得你不知道什么意思？！

二、

1.在php.ini文件中改动error_reporting

   改为：

   error_reporting=E_ALL&~E_NOTICE

如果你不能操作php.ini文件，你可以用下面的方法来实现

2.在你想禁止notice错误提示的页面中加入下面的代码

/* Report all errors except E_NOTICE */

error_reporting(E_ALL ^ E_NOTICE);

希望上面的代码能解决你的问题。

这个还好一些，让你知道怎么搞！打开php.ini，ctrl＋f找到error_reporting，把上面的ctrl＋v过来，浏览自己的网页，诶，真的不显示php notice了，这时真是对这位大哥感激的不行啊，终于帮我们这些菜鸟们解决问题了。

但是，不要急着关闭php.ini，让我们好好看看我们的php.ini：

; E_WARNING         - run-time warnings (non-fatal errors)

;   - Show all errors, except for notices and coding standards warnings

;

;error_reporting = E_ALL & ~E_NOTICE

;

;   - Show all errors, except for notices

;

;error_reporting = E_ALL & ~E_NOTICE | E_STRICT

;

;   - Show only errors

;

;error_reporting = E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR

;

;   - Show all errors, except coding standards warnings

;

error_reporting  =  E_ALL

虽然是英文的，但是就这么几个英文单词，应该难不倒我们吧！

看完，你会发觉，搜索出来的解决办法似乎不大好，而应该这样：

去掉;error_reporting = E_ALL & ~E_NOTICE这一句全面的;就可以了。

这样做比搜索出来的解决办法简单，而且这样做还保证了php.ini的完整性。

现在，再来看看在网页中对错误报告级别的控制吧！

拿出你的php手册，索引->error_reporting,看到了吧！

The error_reporting() function sets the error_reporting directive at runtime. PHP has many levels of errors, using this function sets that level for the duration (runtime) of your script.

参数

level

The new error_reporting level. It takes on either a bitmask, or named constants. Using named constants is strongly encouraged to ensure compatibility for future versions. As error levels are added, the range of integers increases, so older integer-based error levels will not always behave as expected.

The available error level constants are listed below. The actual meanings of these error levels are described in the predefined constants.

2 E_WARNING

4 E_PARSE
