The program to find a string is palindrome or not is :

<?php

function Palindrome($number){ 

    $temp = $number; 

    $new = 0; 

    while (floor($temp)) { 

        $d = $temp % 10; 

        $new = $new * 10 + $d; 

        $temp = $temp/10; 

    } 

    if ($new == $number){ 

        return 1; 

    }

    else{

        return 0;

    }

} 

$original = 257752;

if (Palindrome($original)){ 

    echo "Palindrome"; 

}

else {
