Program for palindrome in php

You could use a function like this:

function isPalindrome($string) {

$string = strtolower($string);

return (strrev($string) == $string) ? true : false;

}

and then to check a palindrome call an if statement like so:

if(isPalindrome($test)) {

echo $test.' is a palindrome';

}

else {

echo $test.' is not a palindrome';

}
