This means that it's not possible to interrupt the process using Ctrl+C. To reproduce, run php -S localhost:8000 on if (!empty($_GET['self'])) { echo 'content'; } else { echo file_get_contents('http://localhost:8000?self=1'); } try to access http://localhost:8000/ and then try to exit the built-in server. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79564&edit=1
