Although you can turn on zend engine 1 compatibility, if you intend to distribute your code you cannot expect this on most servers. Another way to pass by value is to use the __clone method.
function test($orig, $clone) { $orig->x = 'I am the original.'; $clone->x = 'I am a clone.'; print_r($orig); // should be different since this is a copy, not a reference print_r($clone); }
class foo {}
$orig = new foo(); test($orig, $orig->__clone());
Fatal error: Cannot call __clone() method on objects - use 'clone $obj' instead... Should be:
test($orig, clone($orig));
