Thanks,

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));

I believe this is possible with the following setting in php.ini: zend.ze1_compatibility_mode = On This should turn on PHP5's backwards compatibility with PHP4 (meaning that the objects are passed by value instead of by reference... the old way). -- Regards, Ben Ramsey http://benramsey.com --- http://www.phpcommunity.org/ Open Source, Open Community Visit for more information or to join the movement. --- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
