Answer 1

/**
 * Process function.
 * For lack of a better name.
 */
function process($f, $l, $subject)
{
    return preg_replace(sprintf('/%s.*?%s/', preg_quote($f), preg_quote($l)), '', $subject);
}

$f = 'n';
$l = 's';

echo process($f, $l, 'Hello my last name is Doe and my first name is John');

Output:

Hello my last  Doe at  John

I added utility, but it is effectively the same as preg_replace('/n.*?s/', '', $subject).
