Bug description:Feature Request: __cast magic function
Description:
------------
I think it'd be a useful tool to add a __cast($to) magic function to the
Classes and Objects category of PHP syntax. What said function would do is
allow the programmer to specify the return values of casting a user-land
object into one of the built-in data types. I.E. using (int) MyObject would
invoke the __cast() method passing it the 'int' type. In such a case, the
programmer could then specify what is returned when cast to, per se,
int's.
<?php
class MyObject {
public $myValue = null;
public function __construct($value) {
$this->myValue = $value;
}
public function __cast($to = 'string') {
switch ($to) {
case 'string':
return 'The value of myValue is: ' . (string)
$this->myValue;
case 'int':
return strlen($this->myValue);
}
}
}
$myObject = new MyObject('I am a string');
print (int) $myObject; // Output: 13
?>
