(PHP 3, PHP 4, PHP 5)

mysql_drop_db -- Drop (delete) a MySQL database

## Description

bool mysql_drop_db ( string database_name [, resource link_identifier] )

mysql_drop_db() attempts to drop (remove) an entire database from the server associated with the specified link identifier. This function is deprecated, it is preferable to use mysql_query() to issue a sql DROP DATABASE statement instead.

## Parameters

database_name

  The name of the database that will be deleted.

link_identifier

  The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If by chance no connection is found or established, an `E_WARNING` level warning is generated.

## Return Values

�\�^��`TRUE`�Ѧ^��`FALSE`�C

## �d��
