Bug Type: Documentation problem
Operating System: Fedora
PHP Version: Irrelevant
New Comment:
This is expected behavior for ArrayObject:offsetGet(). The array in
your reproduce code has only associative keys, so there is no value at
the integer index 2:
$ php
<?php
$array_3=array("this"=>"0", "is"=>"1",
"life"=> "hello");
$array_3_obj = new ArrayObject($array_3);
print $array_3_obj->offsetGet(2)."\n";
print $array_3_obj->offsetGet("is")."\n";
$array_4_obj = new ArrayObject(array("0","1","hello"));
print $array_4_obj->offsetGet(2)."\n";
?>
^D
Notice: Undefined offset: 2 in - on line 4
1
hello
$
If you truly want the third element of an associative array regardless
of key, you may be looking for ArrayIterator.

Description:
------------
ArrayObject::offsetGet() does NOT return the value corresponding to a
given index as documented, but actually requires a key (NOT an int
$index) as input and returns a value given this key. This was determined
through testing.
Reproduce code:
---------------
A sample array:
$array_3=array("this"=>"0", "is"=>"1",
"life"=> "hello");
$array_3_obj = new ArrayObject($array_3);
print $array_3_obj->offsetGet(2);
Expected result:
----------------
hello
Actual result:
--------------
PHP Notice: Undefined offset: 2
