MySQL错误信息，mysql_connect（），有什么方法可以修复它吗？

Question

So this is the error message:

PHP Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead

This is the affected piece of code:

class wdClient {

    var $dbLink;                // The database link
    var $prefix;                // Table prefix
    var $script;                // The script running

    /**
     * Construct a new directory object.
     */
    function wdClient() {
        error_reporting(E_ALL ^ E_NOTICE);

        $this->prefix = WDDBPREFIX;

        // Connect to the database
        $this->dbLink = mysql_connect(WDDBHOST, WDDBUSER, WDDBPASSWD);

        // Select the database
        mysql_select_db(WDDBNAME, $this->dbLink) or die('Sorry, The site is currently unavailable!');
    }

where WDDBPREFIX, WDDBHOST, WDDBUSER, WDDBPASSWD, WDDBNAME are already defined in a config file.

I have tried simply using mysqli_connect instead of mysql_connect but it's not working.

Note: Never use MySQL, use this method!

//MySQLi information

        $db_host     = "localhost";
        $db_username = "username";
        $db_password = "password";

        //connect to mysqli database (Host/Username/Password)
        $connection = mysqli_connect($db_host, $db_username, $db_password) or die("Error " . mysqli_error());

        //select MySQLi dabatase table
        $db = mysqli_select_db($connection, "table") or die("Error " . mysqli_error());

Good luck!
