Hi all

I recently needed seek functionality in arrays, and couldn't find it in =
the regular set of array functions, so I wrote a function for it. (Seek =
=3D getting an array value based on the position (or offset, if you want =
to call it like that), and not the key of the item)

Basically you can use it like this:
$input =3D array(3, 'bar', 'baz');
echo array_seek($input, 2); // returns 'baz'
echo array_seek($input, 0); // returns 3
echo array_seek($input, 5); // returns NULL, emits an out of range =
warning

I was wondering if it's useful to add this to the family of array =
functions. I know there is a somewhat similar thing in SPL =
(ArrayIterator::seek), but that doesn't work exactly like what I was =
aiming for.

Attached is a patch for the function against the 5.3 branch. If =
approved, I could add it to svn + testcases + docs. Feedback please :-)


Kind regards,
Felix
