(PHP 4, PHP 5)

mysql_drop_dbDrop (delete) a MySQL database

Warning

This function was deprecated in PHP 4.3.0, and will be removed in the future, along with the entirety of the original MySQL extension. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

  • Execute a DROP DATABASE query

Description

bool mysql_drop_db ( string $database_name [, resource $link_identifier = NULL ] )

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 an 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 no connection is found or established, an E_WARNING level error is generated.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 mysql_drop_db() alternative example

<?php
$link 
mysql_connect('localhost''mysql_user''mysql_password');
if (!
$link) {
    die(
'Could not connect: ' mysql_error());
}

$sql 'DROP DATABASE my_db';
if (
mysql_query($sql$link)) {
    echo 
"Database my_db was successfully dropped\n";
} else {
    echo 
'Error dropping database: ' mysql_error() . "\n";
}
?>

Notes

Warning

This function will not be available if the MySQL extension was built against a MySQL 4.x client library.

Note:

For backward compatibility, the following deprecated alias may be used: mysql_dropdb()
