Voorbeeld: example

<?php
// PHP comment here

/*
 * Another PHP comment
 */

echo        php_strip_whitespace(__FILE__);
// Newlines are considered whitespace, and are removed too:
do_nothing();
?>

<?php
 echo php_strip_whitespace(__FILE__); do_nothing(); ?>

Notice the PHP comments are gone, as are the whitespace and newline after the first echo statement.
