Hi,

slightly modified version of the original patch
http://valokuva.org/~mikko/array_seek.patch.txt. The difference to the
original is that the iterator position is left where the user seeked
to. So something like following should work:

<?php
$arr =3D array("the", "brown", "fox", "and", "so", "on");

echo array_seek($arr, 1) . "\n"; // brown
echo next($arr) . "\n"; // fox
?>

Not sure how useful it is to have this in core but I do remember for
looking for a seek function for arrays before.
