PHP Manual


(PHP 4, PHP 5)

mysql_list_dbsList databases available on a MySQL server


resource mysql_list_dbs ([ resource $link_identifier = NULL ] )

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


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



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().


Example #1 mysql_list_dbs() example

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

while (
$row mysql_fetch_assoc($res)) {
$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)) {
$row->Database "\n";

The above example will output something similar to:




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