php code for perfect palindrome

<?php

    $word  = array("test","racecar","axe","madam","hu","ada");

    for($i=0;$i<=5;$i++)
    {
            if(strlen($word[$i])>2)

                        {
                            echo"<p>$word[$i] is a perfect palindrome</p>";
                        }
                   
                }

            }
            else
           
            if(strlen($word[$i])<3)
            {
                    echo"<p>$word[$i] is not a palindrome bacause it has less than 3 characters</p>";
            }
            if(strlen($word[$i])%2 !=1)
