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:
omysqli_select_db(3)
o PDO::__construct (part of dsn)
bool mysql_select_db (string $database_name, [resource $link_identifier = NULL])
DESCRIPTION
Sets the current active database on the server that's associated with the specified link identifier. Every subsequent call to
mysql_query(3) will be made on the active database.
o $database_name
- The name of the database that is to be selected.
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 TRUE on success or FALSE on failure.
