PHP search engine script
The search engine on my website (Jolly Roger's Ship ) is created using PHP. I wanted to put a search engine on my website, but I couldn't find a single tutorial out there, so instead I'm posting my source code and hope it helps people out. It uses two files 'results.php' and 'search.php' along with text files which contain all the sites the search engine can look for.

The text files that the search engine looks through are structured in the following manner:
TitleEOINPUTDescriptionEOINPUTurlEOINPUTkeywordsEOINPUT The EOINPUT are the tags used to separate the content based on heredoc syntax. So in the previous structure you'd only have one website. For instance, my website's particular descriptor would look like this: Jolly Roger's Ship :: Ver. 1.3EOINPUTJolly Roger's Ship, the only website on the net powered by atomic kittens.EOINPUThttp://grimpirate.t35.com/EOINPUTgrimpirate, grim pirate, jr, jolly roger's ship, ray dream, search engine, jrsearch, haohmaru faq, haohmaru strategy guide, samurai showdown trading cards, vagrant skull, online comic, guilty gear gif, guilty gear x gif, anime reviews, anime intros, anime openings, super robot wars alpha buddy icons, dungeons and dragons, dnd accurate combat engine, nyko air flo pc controller, mugen, cd cases, cd slips, ansi c program, source code, php5, jrforum, forum, webboardEOINPUT The title, description, and keywords are taken directly from the particular site from the meta tags available in the headers of most main pages of a site. If there's more than one website in a particular database, the descriptors are appended to one another.
