PHP Tricks - PHP 5 clone in PHP4

[ovi]

PHP 5 handles object differently from PHP4

In PHP4
$new_object = $object;
will copy $object to $new_object

In PHP5
The $new_object will point to $ojbect, kind of like Java.

The correct syntax in PHP5 should be:
$new_object = clone($object);



It's all good but create lots of confusion.
To make the two compatible, here's a clone function that works for both PHP 4 and PHP5:

/* ************************************** Backward compatible
 */ function php4_clone($object) {
  if (version_compare(phpversion(), '5.0') < 0) {
   return $object;
  } else {
   return @clone($object);
  }
 }

To use the function: $object=php4_clone($old_object); It works on both PHP4 and PHP5
