A perfect palindrome is a word or phrase that is identical forward or backward, such as the word racecar, mom, or dad. An example of a standard palindrome is Madam, Im Adam because the characters are identical forwards or backwards, provided you remove the spaces, and punctuation marks. Write a script that checks whether a word entered by a user is a palindrome. To check for a standard palindrome use a function to remove the punctuation marks (comma, apostrophe, period, and exclamation point) and a function to remove the extra spaces. Use an HTML document containing a form with a single textbox to enter the string text and a single script to display and process the form. DO NOT USE preg_replace to remove characters. No credit will be received if this function is used. PLEASE DO NOT USE PREG_REPLACE MUST BE IN PHP FORM!!!!!!
