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