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;
}
}
}
?>
