Examples

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;
       }
   }
}
?>
