Don't know if this is a bug or a feature...

-foo.php----------------------------------------
<?php
if (!$bar) {
    $bar = true;
    include(__FILE__);
    exit;
}
function foo() {
    return true;
}
?>
-/foo.php----------------------------------------

This is a VERY simplified version of a script i'm working on. foo() should only be declared once but PHP says:
<b>Fatal error</b>:  Cannot redeclare foo() in <b>/home/roland/tmp/foo.php</b> on line <b>7</b><br>

ok, i know how a can work around this problem... in this case just put the rest of the file into the else-statement. But nevertheless it is an interesting phenomen...

It's a dupe... can't find the bug anymore, but it is a dupe.

"should only be declared once" is true,
and on the second try it gives an error
as it *can* only be declared once instead
of just silently ignoring it
(there's no practical way for the parser
 to find out that it is *exactly* the same
 definition)
