PHP #1 Palindrome - Answer for https://www.testdome.com/questions/php/palindrome/7320?visibility=1&skillId=5

palindrome.php

<?php
class Palindrome
{
    public static function isPalindrome($word)
    {
        $word = str_replace(' ', '', $word); 
        $word = preg_replace('/[^A-Za-z0-9\-]/', '', $word); 
        $word = strtolower($word); 
        $word_ = strrev($word);
        if ($word_ == $word) {
            return true;
        } 
        else {
            return false;
        }
    }
}

echo Palindrome::isPalindrome('Deleveled');

I'm baffled, for some reason this doesn't pass and I cannot get anything to pass. I feel like the tests are broken... WDYT?

my code was:

function isPalindrome(string $word): bool
{
    if (preg_match("/^[a-zA-Z ]*$/i", $word)) {
        $wordArray = str_split(strtolower($word));
        if ($wordArray === array_reverse($wordArray)) {
            return true;
        } else {
            return false;
        }
    } else {
        return false;
    }
}

Ok scratch that your answer does work, I guess it wants you actually call the function, nm.
