PHP - Banned Ips Flaw
hello
i have the following question i have a script that gets the user ip and if the ip is in the 'file' it redirects it to google <?php $ip=$_SERVER['REMOTE_ADDR']; $file=file('bad_ips'); foreach($file as $files){ if(stristr($files, $ip) === FALSE) { header('location:index1.php'); }else { header('location:http://google.com'); } } ?> in the file the ips are line by line example: 2.2.2.2 4.4.4.4 but the problem is this if the ip `2.2.2.2` enters i wnat to search in the file for just 2.2 if searches only if i put the entire ip in the `file` 2.2.2.2 Similar TutorialsI want to get the COUNT if any of these fields (Fielda, Fieldb, Fieldc, Fieldd, Fielde, Fieldf, Fieldg, Fieldh) contain the word "Banned". But this code doesn't work. $like = count("Fielda, Fieldb, Fieldc, Fieldd, Fielde, Fieldf, Fieldg, Fieldh LIKE '%".implode("%' OR Fielda, Fieldb, Fieldc, Fieldd, Fielde, Fieldf, Fieldg, Fieldh LIKE '%", explode('Banned'))."%'"); echo($like); My Project: Online school note sharing for my university. How: You upload your note(s) get credits and with those credits buy other notes to download. Problem: Whats to stop someone from uploading a note they have downloaded. Security: Currently I have all notes go through an approval system where a staff member views the note sees if it is a legit note then approves it granting the user credits and making the note downloadable. So does anyone have any theories about how I could stop someone from uploading a file that they have uploaded before or have downloaded? timestamps on files md5checksums anything I need to find a way to fix this error and I have no idea. Im wanting to not allow people to post any links in the comments section of a form (spammers) and have created a comma delimited list of essentially of every known domain name extension. To apply the filter I have the following code: Code: [Select] $WordAllowed = true; $BannedWords = explode(",", ReadDB($Options["ban_words"])); if (count($BannedWords)>0) { $checkComment = strtolower($_REQUEST["comment"]); for($i=0;$i<count($BannedWords);$i++){ $banWord = trim($BannedWords[$i]); if (trim($BannedWords[$i])<>'') { if(preg_match("/".$banWord."/i", $checkComment)){ $WordAllowed = false; break; } } } } if($WordAllowed==false) { $SysMessage = $OptionsLang["Banned_word_used"]; } else { Insert into my table I could have sworn this was working last time I was in this code but recently checking it again it is blocking pretty much everything claiming a banned word is used. The only thing I can get to post is 'lol'. Trying funny phrases like: first! or Great information, thanks, this is a test of the comment section, etc....they all get flagged Can anyone with fresh eyes assist? Im weary and frustrated and its been forever since I wrapped my head around this. My banned word list: Code: [Select] www,http,com,org,.aero,.asia,.biz,.com,.coop,.edu,.gov,.info,.int,.jobs,.mil,.mobi,.museum,.name,.net,.org, .pro,.tel,.travel,.xxx,.a,.bitnet,.ac,.ad,.ae,.af,.ag,.ai,.al,.am,.an,.ao,.aq,.ar,.as,.at,.au,.aw,.az,.ba,.bb,.bd,.be,.bf,.bg ,.bh,.bi,.bj,.bm,.bn,.bo,.br,.bs,.bt,.bv,.bw,.by,.bz,.ca,.cc,.cf,.cg,.ch,.ci,.ck,.cl,.cm,.cn,.co,.com,.cr,.cs,.cu,.cv,.cx,.cy,.cz ,.de,.dj,.dk,.dm,.do,.dz,.ec,.edu,.ee,.eg,.eh,.er,.es,.et,.fi,.fj,.fk,.fm,.fo,.fr,.fx,.ga,.gb,.gd,.ge,.gf,.gh,.gi,.gl,.gm,.gn ,.gov,.gp,.gq,.gr,.gs,.gt,.gu,.gw,.gy,.hk,.hm,.hn,.hr,.ht,.hu,.id,.ie,.il,.in,.io,.iq,.ir,.is,.it,.jm,.jo,.jp,.ke,.kg,.kh,.ki,.km ,.kn,.kp,.kr,.kw,.ky,.kz,.la,.lb,.lc,.li,.lk,.lr,.ls,.lt,.lu,.lv,.ly,.ma,.mc,.md,.mg,.mh,.mil,.mk,.ml,.mm,.mn,.mo,.mp,.mq,.mr, .ms,.mt,.mu,.mv,.mw,.mx,.my,.mz,.na,.nc,.ne,.net,.nf,.ng,.ni,.nl,.no,.np,.nr,.nt,.nu,.nz,.om,.org,.pa,.pe,.pf,.pg,.ph, .pk,.pl,.pm,.pn,.pr,.pt,.pw,.py,.qa,.re,.ro,.ru,.rw,.sa,.sb,.sc,.sd,.se,.sg,.sh,.si,.sj,.sk,.sl,.sm,.sn,.so,.sr,.st,.su,.sv, .sy,.sz,.tc,.td,.tf,.tg,.th,.tj,.tk,.tm,.tn,.to,.tp,.tr,.tt,.tv,.tw,.tz,.ua,.ug,.uk,.um,.us,.uy,.uz,.va,.vc,.ve,.vg,.vi,.vn,.vu,.wf, .ws,.ye,.yt,.yu,.za,.zm,.zr,.zw Thanks in advance for any help |
