note 79629 added to function.gethostbyname

I put this in a prepend script for all my websites to cut down the amount of abuse by automated scripts. <?PHP $blacklists = array('web.sorbs.net'); $parts = explode('.', $_SERVER['REMOTE_ADDR']); $ip = implode('.', array_reverse($parts)) . '.'; foreach($blacklists as $bl) { $check = $ip . $bl; if ($check != gethostbyname($check)) { error_log('PHP Security: [DNSBL] - ' . $_SERVER['REMOTE_ADDR'] . ' - ' . $bl); die('Put a detailed error here so the client knows why they have been blocked'); } } ?> ---- Server IP: 203.16.234.90 Probable Submitter: 58.105.121.252 ---- Manual Page -- http://www.php.net/manual/en/function.gethostbyname.php Edit -- https://master.php.net/note/edit/79629 Del: integrated -- https://master.php.net/note/delete/79629/integrated Del: useless -- https://master.php.net/note/delete/79629/useless Del: bad code -- https://master.php.net/note/delete/79629/bad+code Del: spam -- https://master.php.net/note/delete/79629/spam Del: non-english -- https://master.php.net/note/delete/79629/non-english Del: in docs -- https://master.php.net/note/delete/79629/in+docs Del: other reasons-- https://master.php.net/note/delete/79629 Reject -- https://master.php.net/note/reject/79629 Search -- https://master.php.net/manage/user-notes.php
