mysql_list_dbs

(PHP 4, PHP 5)

mysql_list_dbsList databases available on a MySQL server

Warning

This extension is deprecated as of PHP 5.5.0, and will be removed in the future. 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:

  • SQL Query: SHOW DATABASES

Description

resource mysql_list_dbs ([ resource $link_identifier = NULL ] )

Returns a result pointer containing the databases available from the current mysql daemon.

Warning

This function has been DEPRECATED as of PHP 5.4.0. Relying on this function is highly discouraged.

Parameters

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 a result pointer resource on success, or FALSE on failure. Use the mysql_tablename() function to traverse this result pointer, or any function for result tables, such as mysql_fetch_array().

Examples

Example #1 mysql_list_dbs() example

<?php
// Usage without mysql_list_dbs()
$link mysql_connect('localhost''mysql_user''mysql_password');
$res mysql_query("SHOW DATABASES");

while (
$row mysql_fetch_assoc($res)) {
    echo 
$row['Database'] . "\n";
}

// Deprecated as of PHP 5.4.0
$link mysql_connect('localhost''mysql_user''mysql_password');
$db_list mysql_list_dbs($link);

while (
$row mysql_fetch_object($db_list)) {
     echo 
$row->Database "\n";
}
?>

The above example will output something similar to:

database1
database2
database3

Notes

Note:

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

The result pointer contains only the databases for which the mysql_user has the select priviledge granted.
