This will not be fixed anytime soon. It is a deep seated problem in the implementation
and fixing it would cause speed problems and numerous other problems, This is somthing
that can be coded around too so should not cause massive problems.

Is this the same as bug 6417?

OK, this only affects objects in the array whose methods
have been accessed. Other objects are still copies. It
also works on php-4.0.3pl1 on the Win32 platform.

A short script:
<?php
class test_class_2{
var $name;
function distort_reality(){
echo("Method Called.<br>n");
return;
}
}
$a[] = new test_class_2;
$a[0]->name = 'Original';
echo('$b = $a<br>'."n");
$b = $a;
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br><p>n");
echo("Change contents for $b<br>n");
$b[0]->name = 'Copy';
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br><p>n");
$a[0]->distort_reality();
echo('Once again, $b = $a<br>'."n");
$b = $a;
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br><p>n");
echo("Change contents for $b<br>n");
$b[0]->name = 'Copy';
echo("Original contains: {$a[0]->name}<br>n");
echo("Copy contains: {$b[0]->name}<br>n");
?>
The output from the script:
$b = $a
Original contains: Original
Copy contains: Original
Change contents for $b
Original contains: Original
Copy contains: Copy
Method Called.
Once again, $b = $a
Original contains: Original
Copy contains: Original
Change contents for $b
Original contains: Copy
Copy contains: Copy
Basically, if $a is an array of objects and any method of an object is called any
subsequent copy of $a becomes linked to the original. Any change to the copy
propagates through to the original.
