{
public static $table=" table 1 ";
public static $colum1=" colum1 ";
public static $colum2=" colum2 ";
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')" ;
}
}

parent::__construct();
//$this->object=new sqlQuery();
}
function insert()
{
$query=new sqlQuery();
$query1=new sqlQuery();
$call=$query1->insert('active','10');
}
}
Help me thanks in advance.....

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.
