[PHP-NOTES] note 130663 added to function.in-array

It's worth the notice that in_array is case-sensitive.
Apart from the very first option of make all lowercase or uppercase, and then compare, I found this elegant solution:

<?php

function in_arrayi(float|int|string $needle, array $haystack):bool {
	return (bool)array_uintersect([$needle],$haystack,strcasecmp(...));
}

$needle = "abc";
$haystack = ["Abc","deF","gHi"];
$result = in_arrayi($needle,$haystack);

var_dump($result);

?>
