MYSQL_LIST_DBS(3) 1 MYSQL_LIST_DBS(3) mysql_list_dbs - List databases available on a MySQL server SYNOPSIS
Warning This function was deprecated in PHP 5.4.0, and will be removed in the future, along with the entirety of the original MySQL exten- sion. 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: oSQL Query: SHOW DATABASES resource mysql_list_dbs ([resource $link_identifier = NULL]) DESCRIPTION
Returns a result pointer containing the databases available from the current mysql daemon. o $ link_identifier -The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect(3) is assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection is found or established, an E_WARNING level error is generated. Returns a result pointer resource on success, or FALSE on failure. Use the mysql_tablename(3) function to traverse this result pointer, or any function for result tables, such as mysql_fetch_array(3). Example #1 mysql_list_dbs(3) 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'] . " "; } // 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 . " "; } ?> The above example will output something similar to: database1 database2 database3 Note For backward compatibility, the following deprecated alias may be used: mysql_listdbs(3) mysql_db_name(3), mysql_select_db(3).
