PHP Program

Complete PHP code (and HTML Code)

Using functions to abstract the logic away from the rest of your code makes it easier to read and maintain. PHP provides a number of useful functions as standard, and this week you will use some of these functions to obtain information.

Create a program that compares two strings provided on an HTML form, and determine if the two strings are anagrams. The HTML page asks the user for the input strings, and the PHP program will generate another HTML page with the result. For example:

Enter string #1: NOTE
Enter string #2: TONE

"NOTE" and "TONE" are anagrams

You should also check that the two strings are of the same length before attempting to evaluate them as anagrams.

   $string_2=strtoupper($_POST['word2']);

function anagram($string_1, $string_2){
if(strlen($string_1)==(strlen($string_2))){
   if (count_chars($string_1, 1) == count_chars($string_2, 1)) {
       echo "Enter String #1 : <b>".$string_1."</b></br>";
       echo "Enter String #2 : <b>".$string_2."</b></br>";

   }else{
   echo "Enter String #1 : <b>".$string_1."</b></br>";
       echo "Enter String #2 : <b>".$string_2."</b></br>";
   echo '<b>"'.$string_1.'"</b> and <b>"'.$string_2.'"</b> are not an anagrams';
   }
