php - Deprecated: mysql_real_escape_string(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO

I'm actually looking for an alternative to mysql_real_escape_string to
solve this error.
in php 5.4 it worked perfectly but no longer in php 5.5

$this->mysqli = new mysqli($this->host, $this->user, $this->pass, $this->name);
// in class user
public function __set($p_sProperty, $p_vValue)
        {   
            switch($p_sProperty)
            {    
// this is marked as the error
case "Email":
             $this->Email = **mysql_real_escape_string**($p_vValue); 

                break;
}
}

Answer

You using MySQLi so use mysqli_real_escape_string():

$this->Email = $this->mysqli->real_escape_string($p_vValue);
