PHP Bug Type: Scripting Engine problem
Bug description: Calling class instance inside other class produces memory
issues
Description:
------------
I'm building a huge PHP5 script that is using classes.
However somehow by returning function data to a previous call thru another
class the data is not returned but a NULL instead.
The below script has a similar layout as mine but as i said mine is huge,
so if thisone works as expected i will figure out a way to provide my huge
reproducable bug.
Reproduce code:
---------------
<?php
class A
{
public function foo()
{
$foo = 'foo';
return $foo;
}
}
class B
{
public function bar()
{
global $A;
$bar = $A->foo();
return $bar;
}
}
class C
{
public function test()
{
global $B;
$test = $B->bar();
echo gettype($test);
}
}
$A = new A();
$B = new B();
C::test();
Expected result:
----------------
string
Actual result:
--------------
NULL
