Description:
------------
The constructor over loading is not allowed in PHP however for being OOPS based language it should.

Reproduce code:
---------------
class PDF extends FPDF
{

public function __construct($one){
	echo "one";
}
public function __construct($one,$two){
	echo "two";
}
public function __construct(){
    echo "blank";
}
}

Expected result:
----------------
it should allow us contructor overloading.

Actual result:
--------------
error: can not redeclare function.
