Reported By: Christian dot Lefebvre at atosorigin dot com
Status: Open
Bug Type: Scripting Engine problem
Operating System: linux
PHP Version: 5.0.0RC1
New Comment:
Same behavior if exit is used instead of return, i.e:
if(defined("MY_CONSTANT")) exit;
define("MY_CONSTANT", "1");
function foo() {}
The only workaround seems to be using an else statement:
if(defined("MY_CONSTANT") return;
else {
function foo() {}
}
how sad...

#18590 seems to be the same bug, but without
explanation nor test case. and it's marked "no feedback" :-(

Description:
------------
lot of php3 codes begin include files by a
if(defined(..)) return; define(..)
to simulate include_once behavior
it works fine with php4, but with php5, functions
declared after this return raise "cannot redeclare" error
when the file is included twice.
Reproduce code:
---------------
t1.php :
<?php
include("t2.php");
toto();
include("t2.php");
toto();
?>
t2.php :
<?php
error_log("in t2");
if (defined("_T2_INCLUDED")) {
error_log("already went there");
return;
}
define("_T2_INCLUDED", "1");
error_log("still in t2");
function toto() {
echo "Here am I !!\n";
}
?>
Expected result:
----------------
with php4 :
in t2
still in t2
Here am I !!
in t2
already went there
Here am I !!
Actual result:
--------------
with php5 :
in t2
still in t2
Here am I !!
Fatal error: Cannot redeclare toto() (previously declared in t2.php:13)
in t2.php on line 14
