    Here is a simple example PHP script using the tokenizer that will read in a PHP file, strip all comments from the source and print the pure code only.

    Example #1 Strip comments with the tokenizer

    <?php
    $source     = file_get_contents('example.php');
    $tokens = token_get_all($source);

    foreach (    $tokens as $token) {
       if (    is_string($token)) {
               // simple 1-character token
               echo $token;
       } else {
               // token array
               list($id, $text) = $token;

           switch (    $id) { 
               case     T_COMMENT: 
               case     T_DOC_COMMENT:
                       // no action on comments
                       break;

               default:
                       // anything else -> output "as is"
                       echo $text;
                   break;
           }
       }
    }
    ?>
