php str_ireplace without losing case

Question

is it possible to run str_ireplace without it destroying the original casing?

For instance:

$txt = \"Hello How Are You\";
$a = \"are\";
$h = \"hello\

Not beautiful, but should work.

function str_replace_alt($search,$replace,$string)
{
    $uppercase_search = strtoupper($search);
    $titleCase_search = ucwords($search);
    $lowercase_replace = strtolower($replace);
    $uppercase_replace = strtoupper($replace);
    $titleCase_replace = ucwords($replace);

    $string = str_replace($uppercase_search,$uppercase_replace,$string);
    $string = str_replace($titleCase_search,$titleCase_replace,$string);
    $string = str_ireplace($search,$lowercase_replace,$string);

    return $string;
}
