how to replace special characters with the ones they’re based on in PHP?

Here is sample code:

$code="CSC113α";//other codes PHY123β,MAT324δ

    ////return last character of the code
    $lastchar=substr($code, -1);

    // returns rest code without last character..
    $rest = substr($code, 0, -1);  

    //Make standard course_ID with a,ß..
    switch ($lastchar)
    {
    case '&alpha;':{
      $lastchar='A';
      $id=$rest.$lastchar ;
      $full_course_id=$id;
      break;
    }
    case '&beta;':{
      $lastchar='B';
      $id=$rest.$lastchar ;
      $full_course_id=$id;
      break;
    }
    case '&delta;':{
      $lastchar='D';
      $id=$rest.$lastchar ;
      $full_course_id=$id;
      break;
    }
    default:
      $full_course_id=$code;
    }

I want get final out put like 'CSC113A'..but this switch code doesn't work for me...please help me to do this...thxx in advanced....

How can you compare a single character against strings like `α`? — Ja͢ck, Dec 14 '12 at 13:29
your cases won't match `$lastchar` as it is a single character and they are not. — dnagirl, Dec 14 '12 at 13:31
@jack: α=α that's why put it there.....becoz using α for case code still not working frnd.... — Dong Li, Dec 14 '12 at 13:32

Why not simply use the function str_replace? I've done a test and it works for me!

<?php
$code="CSC113α";
$full_course_id = str_replace(array('α','β', 'δ'), array('A', 'B', 'D'), $code);
