mysql_select_db - Select a MySQL database

SYNOPSIS
       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.

       Example #1
