I'd recommend a 404 over a 403 considering a 403 proves there is something worth hacking into. index.php: <?php define('isdoc',1); include('includes/include.sqlfunctions.php'); // Rest of code for index.php ?> include.sqlfunctions.php (or other include file): <?php if(isdoc !== 1) // Not identical to 1 { header('HTTP/1.1 404 Not Found'); echo "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN\">\n<html><head>\n<title>404 Not Found</title>\n</head>"; echo "<body>\n<h1>Not Found</h1>\n<p>The requested URL ".$_SERVER['REQUEST_URI']." was not found on this server.</p>\n"; echo "<hr>\n".$_SERVER['SERVER_SIGNATURE']."\n</body></html>\n"; // Echo output similar to Apache's default 404 (if thats what you're using) exit; } // Rest of code for this include ?> ---- Server IP: 203.16.234.90 Probable Submitter: 150.101.110.53 ---- Manual Page -- http://www.php.net/manual/en/security.php Edit -- https://master.php.net/note/edit/72806 Del: integrated -- https://master.php.net/note/delete/72806/integrated Del: useless -- https://master.php.net/note/delete/72806/useless Del: bad code -- https://master.php.net/note/delete/72806/bad+code Del: spam -- https://master.php.net/note/delete/72806/spam Del: non-english -- https://master.php.net/note/delete/72806/non-english Del: in docs -- https://master.php.net/note/delete/72806/in+docs Del: other reasons-- https://master.php.net/note/delete/72806 Reject -- https://master.php.net/note/reject/72806 Search -- https://master.php.net/manage/user-notes.php
