Hi Allen following is an example of overloading with the help of magic methods:


<?php
class TDshape {
const Pi = 3.142 ;  // constant value
 function __call($fname, $argument){
    if($name == 'area')
        switch(count($argument)){
            case 0 : return 0 ;
            case 1 : return self::Pi * $argument[0] ; // 3.14 * 5
            case 2 : return $argument[0] * $argument[1];  // 5 * 10
        }
    }
}
$circle = new TDshape();
echo "Area of circle:".$circle->area(5)."</br>"; // display the area of circle
 $rect = new TDshape();
echo "Area of rectangle:".$rect->area(5,10); // display area of rectangle
?>
