error_reporting

--------------------------------------------------------------------------------

----Sets which PHP errors are reported

设置PHP错误报告

The error_reporting() function sets the error_reporting directory at runtime.PHP has many levels of errors,using this function sets that level for the duration(runtime) of your script.If the optional level7 is not set,error_reporting() will just return the current reporting level.

error_reporting() 函数在运行的时候设置error_reporting目录.

PHP有很多的错误,使用此功能设置你的script.如果你选购的水平是没有设置的持续时间(运行时),打开error_reporting() 方法会返回当前的错误报告级别.

ini_set(PHP4, PHP5)

ini_set -- Sets the value of a configuration option
