#50687 [Bgs]: array_reverse return values missing NULL
ID: 50687
Updated by: kalle@php.net
Reported By: hanskrentel at yahoo dot de
Status: Bogus
Bug Type: Documentation problem
Operating System: win
PHP Version: 5.2.8
New Comment:
If you pass an unexpected type to some functions in 5.2.x, they will
emit a warning and return "undefined". 5.3.x is more strict and won't
silently convert incompatible types, and also returns "undefined". So
this report is still bogus.

Sorry for not mentioning that it does a warning as well:
So it does return NULL and it does a warning.
According to the documentation it does return array only, not NULL.

According to the sources, then the only time array_reverse() would
return NULL would also emit an E_WARNING in the 5.2 branch:
2696 if (Z_TYPE_PP(input) != IS_ARRAY) {
2697 php_error_docref(NULL TSRMLS_CC, E_WARNING, "The argument should
be an array");
2698 return;
2699 }

Description:
------------
array_reverse has array as documented return type. while running
var_dump(array_reverse(NULL)); it reported to me NULL. I
think some documentation is missing here.
Reproduce code:
---------------
---
From manual page: function.array-reverse#Return Values
---
Expected result:
----------------
array (Not that I personally would expect that, but the documentation).
Actual result:
--------------
null
