mysql數據庫備份類 - 幫我添加PORT功能

Question

我有一個數據庫備份類，但沒有選項來添加PORT功能來保存遠程數據庫的備份。目前該腳本在默認端口下工作正常。任何人都可以幫助我在這個腳本中添加PORT功能嗎？

$host = $_POST['dbhost']; 
$user = $_POST['dbuser']; 
$password = $_POST['dbpass']; 
$databaseName = $_POST['dbname']; 
$path = "$savepath"; // Put the complete path here -- /home/user/database.sql for example 

// Report all errors 
error_reporting(E_ALL);

*/

define("DB_PASSWORD", $password);

您可以在主機參數中指定端口，即foo.bar:1234。 Check this out for the actual documentation。但是mysql_connect已被棄用，並且很快就會被移除。您應該花時間並升級至mysqli。
