    public static $colum3=" colum3  ";
    public static $colum4=" colum4  ";
    public $value1=" value1 ";
    public $value2="  value2   ";



   public function insert( $value1,$value2)
    {
    echo "INSERT INTO" .static::$table ."(" . static::$colum1 .' , ' .static ::$colum2. ")  VALUES('$value1' , '$value2')" ;        
    }

Late static binding is about parent - children relationships. It's unclear what you want to get. You should have some subclass of sqlQuery to use late static binding. Something like

class gallerySqlQuery extends sqlQuery
{
    protected static $colum1=" status "; // better private or protected
    protected static $colum2=" order "; // you don't need it to be public
    protected static $colum3=" colum3  ";
    protected static $colum4=" colum4  ";
}

in the gallery class you should call the method of this class

$query1=new gallerySqlQuery();
$call=$query1->insert('active','10');

Then, you don't need to declare all these public static $colum1 etc in the sqlQuery class.
