PHP Bug Type: Scripting Engine problem
Bug description: Fatal error: Only variables can be passed by reference
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
