A palindrome is a word or phrase that is identical forward or backward, such as the word “racecar.” A standard palindrome is similar to a perfect palindrome, except that spaces and punctuation are ignored in a standard palindrome. For example, “Madam, I’m Adam” is a standard palindrome because the characters are identical forward or backward, provided you remove the spaces and punctuation marks. Write a script that checks words or phrases stored in two separate string variables to determine if they are a perfect palindrome. After you have tested it, modify the program to check for standard palindromes. Save the perfect palindrome script as PerfectPalindrome.php and the standard palindrome script asStandardPalindrome.php.
