mysql_select_db

(PHP 4, PHP 5, PECL mysql:1.0)

mysql_select_db — Select a MySQL database

Description

bool mysql_select_db ( string $database_name [, resource $link_identifier ] )

Sets the current active database on the server that's associated with the specified link identifier. Every subsequent call to mysql_query() will be made on the active database.

Parameters

database_name: The name of the database that is to be selected.
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 by chance no connection is found or established, an E_WARNING level error is generated.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

$db_selected = mysql_select_db('foo', $link);
