PHP, though. Also, completely ignoring multibyte strings or actually checking word lengths and stuff.
function wordleGuess(string $word, string $solution) {
for ($i = 0; $i < 5; $i++) {
if ($word[$i] === $solution[$i]) {
echo '🟩';
} elseif (strpos($solution, $word[$i]) !== false) {
echo '🟨';
} else {
echo '⬛';
}
}
}
