## 例

`

     string mysql_error ([ resource $link_identifier ] )

`

## 説明

Returns the error text from the last MySQL function. Errors coming back from the MySQL database backend no longer issue warnings. Instead, use mysql_error() to retrieve the error text. Note that this function only returns the error text from the most recently executed MySQL function (not including mysql_error() and mysql_errno()), so if you want to use it, make sure you check the value before calling another MySQL function.

## 戻り値

Returns the error text from the last MySQL function, or '' (empty string) if no error occurred.
