Summary

0001155: Multidimensional array copies contain references to original array

Description

PHP:

<?php
$a1['x']['a'] = 1;
$a2 = $a1;
unset($a1['x']['a']);
print $a2['x']['a'];
?>

On Zend PHP, this prints "1". On Quercus, it prints nothing -- unsetting the second-dimension array element in $a1 also modifies $a2.

This does not happen on the first dimension of an array, only on the second and greater dimensions.

Notes
(0001243) koreth 05-26-06 22:25	A "fix" (which I assume is not optimal for performance reasons) is to comment out the ArrayValueImpl(ArrayValueImpl) constructor so the generic ArrayValueImpl(ArrayValue) one is used instead. That makes the test pass and makes the problems this bug was causing in my real code go away.
