1
Notice: Use of undefined constant name - assumed 'name' in C:\wamp\www\index.php on line 25

1 1 1 都是从数据库输出的类容

我以为是自己写的问题 ，然后我安装了wordpress 也出现这样的东西

Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\www\wp-settings.php on line 520

Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\www\wp-settings.php on line 535

Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\www\wp-settings.php on line 542

Deprecated: Assigning the return value of new by reference is deprecated in C:\wamp\www\wp-settings.php on line 578

Deprecated: Function set_magic_quotes_runtime() is deprecated in C:\wamp\www\wp-settings.php on line 18

这是怎么回事呢？？我是在本地wamp集成环境运行的

Answer 1

在php.ini 里把错误级别改成 all_error^notice
大概就是这样的
意思为输出所有错误，但不显示通知级别的。

Notice代表通知级别的问题 但是不是错误程序，屏蔽notice通知程序可以正常运行。
我一般写的时候都会这样

Answer 2

这是警告，一般没事，你可以在程序的最上面添加error_reporting(0)
这样就不会出现警告了
