Description:
------------
This code works fine on PHP 4 but fails on PHP 5.1.2. I know that I need to try it on the 5.1.6 version but I can't get my suse server to upgrade to it. On PHP 5.1.2 it reports "Fatal error: Cannot redeclare class". If the "extends CTest3" is removed from file test.inc there is no error.
Reproduce code:
---------------
File 1: test.php
<?
require "test2.inc";
require "test2.inc";
?>
File 2: test2.inc
<?
if (defined("CTEST2")) return;
define("CTEST2", 1);
require "test3.inc";
class CTest2 extends CTest3
{
function CTest2()
{
print "Test2";
}
}
?>
File 3: ?test3.inc?
<?
if (defined("CTEST3")) return;
define("CTEST3", 1);
class CTest3
{
function CTest3()
{
print "Test3";
}
}
?>
Expected result:
----------------
No error
Actual result:
--------------
Fatal error: Cannot redeclare class ctest2 in test2.inc on line 16

>if (defined("CTEST2")) return; >define("CTEST2", 1); Classes are declared at compile time, while 'if() return;' is executed at runtime, so this is 100% expected behaviour.
