Find a string within an array (case-insensitive & search for same characters so shortform names will match)

Question

I'm trying to find a way to search my array for a case-insensitive string and the string does NOT have to be exact match... for example: I want to search for "Chris" and my array has a record of "Christopher" which I want this to be a match.

So far I have tried (case-insensitive):

if (preg_grep( "/".$fullname."/i" , $array2 ))

and

if (in_array($fullname, $array2))

but no luck with either one when searching for "Chris" inside my array which contains "Christopher"

What does *no luck* mean? Do you get any errors? Please make an example with input and expected output — Rizier123, Mar 30 '15 at 17:07
No error, it just doesn't find "Chris" inside my array which has "Christopher" — rubberchicken, Mar 30 '15 at 17:09

See the answer given by Alix Axel

preg_grep does the trick:

$input = preg_quote('bl', '~'); // don't forget to quote input string!
$data = array('orange', 'blue', 'green', 'red', 'pink', 'brown', 'black');

$result = preg_grep('~' . $input . '~', $data);

And the difference to OP's code is, besides that it is not case insensitive ? And why do you answer the question when there is already a dupe? – Rizier123 Mar 30 '15 at 17:20

Well this is just redundant to just copy an entire answer! – Rizier123 Mar 30 '15 at 17:31
