On linux systems, you can use exec ("ls /www/", $dir); or $fp = popen ("ls /www/", "r") will do the job. First case, you will have the results in $dir, being an array, one line one element ($dir[0], $dir[1], etc.). In the second case, you open a process file pointer and you ca read from it wirh fgets () conveniently, one line at a time. "r" means you only will be able to read from it, it would be a dumb idea to write into it :) After reached eof, you should close it with pclose(). The first case is lightyears easyer to process, however, with some experience, popen will be much more use of you later. On windows, respectively, use "dir" instead of "ls". You may have to specify full path to ls since it is an aux program. This normally should be "/bin/ls" so use "/bin/ls /www/" for e.g. However, if you have to access your files many times, I suggest you storing the list in a database, so you can select from it easily - even with "where" clauses. -o- >From: "Vojtech Dvorak" <vojtech_dvorak@servind.cz> >Date: Tue, 31 Oct 2000 09:14:27 +0100 >Subject: Re: [PHP-DB] regularly mysql db web update ? without quoting your whole letter, DO NOT do this. This is a very nasty and dirty method to use. Sounds one would sell his monitor and use his matrix printer (anyone remember matrix printers anyway ? :) for output. Why don't you simply have one of your server connect to another running mysql ? If you manage to make this connection between your servers via www, you can find yourself on a very, very, very bad monday morning (ever heard of hackers ?) - o - >Date: 31 Oct 2000 11:23:12 -0000 >From: Matthew Brealey <webmaster@richinstyle.com> >Subject: Search engine > >Hello. > >I'm doing a search engine for a dating site.

For interests, here's a quick and simply idea: give your users have 5+5 fields for their interests, 5 for what they like and 5 what they do not. Instruct them to enter only simple words, so "cat" or "cats" or "car" or "tennis" and then you can search with keywords easily. You can even make statistics for your user's interests, for e.g.When searching for a string, search for the string itself among users' interest, and, if string does not end with an "s", then search for the $string."s" also. This is NOT literally correct at all but will work fine. Best regards, Trap
