Description:
------------
Using is_array() on an instance of ArrayObject returns FALSE. While strictly speaking this is true, it would make sense to return TRUE in most application-level code.

Expected result:
----------------
A solution could be to add an argument to is_array, which relaxes the check to include ArrayObject. Eg. :

bool is_array ( mixed var, [bool strict] )

$obj = new ArrayObject();
is_array($obj, FALSE); // returns TRUE
is_array($obj); // returns FALSE

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

it is an object not an array, use "instanceof ArrayAccess"

I has the interface of an array. Thus, in a logical sense it _is_ an array.

Changed the category to "Feature/Change Request".
