(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

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";
}
?>
