2007.04.04 - Type Casting in PHP

OK so type casting isn't supported in PHP ... HOORAY! So I went to the php help pages and made a wee type casting utility based on the kludge that some other developer came up with - the cool thing about mine is it will let you convert normal variables into objects too!

Here is a wee sample: -

class ClassA

{

    var $a;

    var $b;

    var $c;

    var $d;



    function ClassA()

    {

    }



    function ToString()

    {

        echo "I contain " . $this->a . ", " . $this->b . ", " . $this->c . " and " . $this->d . ".";

    }

}



class Cast0r

{

    function Cast($value, $asObject)

    {

        $value = (object) $value;

        $value_array = explode(":", serialize($value));

        $object_array = explode(":", serialize($asObject));



        $value_array[1] = $object_array[1];

        $value_array[2] = $object_array[2];



        $value_object = unserialize(implode(":", $value_array));



        return $value_object;

    }

}



$my_arr = array(

    "a" => "A",

    "b" => "B",

    "c" => "C",

    "d" => "D"

);



$my_a = Cast0r::Cast($my_arr, new ClassA());

$my_a->ToString();
