palindrome.php

<?php
class Palindrome
{
    public static function isPalindrome($word)
    {
		$temp = '';
		$word = lcfirst($word);
        
		$length = strlen($word);

		for ($i = $length; $i >= 0; --$i) {
			@$temp .= $word[$i];	
		}

		return ($word === $temp);
    }
}

$word === strrev($word) ?

Thank you for this, It didn't come to my mind at first. :)

Here's the refactor with strrev:

`<?php

class Palindrome
{
public static function isPalindrome($word)
{
return (strtolower($word) === strtolower(strrev($word)));
}
}

echo Palindrome::isPalindrome('exe');
echo Palindrome::isPalindrome('Ini');`
