-Status: Bogus
+Status: Open
Bug Type: Scripting Engine problem
PHP Version: 5.1.0b2
New Comment:
Sorry, it's all fair and well making this bogus, but this change breaks
****LOADS**** of existing code, so it is not a bug and it's behavior is
NOT documented. The least you could have done is justify why this is
not a bug and why this change was introduced into the language!
This is really a PHP bug because thi has worked in all versions of PHP
prior to this. There has been nothing in the way of warning or anything
in recent releases to phase in this change in behaviour like there was
with the call by reference thing.
Do you expect many thousands of programmers to change their code
because if this stupid querk.

http://www.php.net/manual/ and the instructions on how to

Description:
------------
This bug is a rehash of 33516, but I can't reopen as I'm not the
original author.
It seems like you can not pass tempories to function / method
parameters.
<?php
class Foo {
public static function bar() {
return array('a' => '1234567890');
}
}
$tmp = Foo::bar();
$var = array_pop($tmp);
?>
Seems to work, but it shouldn't be down to the PHP user (imho) to
implement this as this change in PHP 5.1 breaks a lot of existing code.
Reproduce code:
---------------
<?php
class Foo {
public static function bar() {
return array('a' => '1234567890');
}
}
$var = array_pop(Foo::bar());
?>
Expected result:
----------------
$var = '1234567890';
Foo::bar() gets placed in temporary variable
Actual result:
--------------
Fatal error: Only variables can be passed by reference
