Description:
------------
When constructing ArrayObjects by passing arrays to their constructor subsequent
object comparisons do not return the right result.
Only by using getArrayCopy, we get the proper result.
Test script:
---------------
<?php
$a = array();
$b = array();
$a[] = 0;
$b[] = 0;
echo '$a==$b .. ';
var_dump($a==$b);
$b[] = 1;
echo '$b[] = 1; $a==$b .. ';
var_dump($a==$b);
$a_o = new ModifiedArrayObject($a);
$b_o = new ModifiedArrayObject($b);
echo '$a_o==$b_o .. ';
var_dump($a_o==$b_o);
echo '$a_o->compareTo($b_o) .. ';
var_dump($a_o->compareTo($b_o));
class ModifiedArrayObject extends ArrayObject {
public function compareTo(ArrayObject $a) {
$to = $a->getArrayCopy();
return $this->getArrayCopy() == $to;
}
}
Expected result:
----------------
$a_o == $b_o returns false.
Actual result:
--------------
$a_o == $b_o returns true.
