Cassidoo | Faulty Keyboard

README.md

Solution to Cassidoo's Week of Aug 14, 2023 Challenge

You have a faulty keyboard. Whenever you type a vowel on it (a,e,i,o,u,y), it reverses the string that you have written, instead of typing the character. Typing other characters works as expected. Given a string, return what will be on the screen after typing with your faulty keyboard.

faultyKeeb.php

<?php

function faultyKeeb($string, $result = '') {
	if ($string == '') return $result;

	$char = $string[0];
	if (in_array(strtolower($char), ['a', 'e', 'i', 'o', 'u', 'y'])) {
		return faultyKeeb(substr($string, 1), strrev($result));
	}

	return faultyKeeb(substr($string, 1), $result . $char);
}

var_dump(faultyKeeb('string')); // rtsng
var_dump(faultyKeeb('hello world!')); // w hllrld!
var_dump(faultyKeeb("Onomatopoeia")); // tnmp
var_dump(faultyKeeb("Chris Lagasse")); // ssL sChrg
