RE: [PHP] Counter

But if you know that the counter will increment by 7000 every 24 hours then you don't need a cron job to count this. All you need is to know the time the counter was first started from which can be embedded into the html, get the current time, do some simple math, and then you'll know the value of the counter at that moment in time. Meta refresh the page every so often and your counter will increment. All of this can be done on the client side using javascript, which I believe this was what Mark Douglas' original answer to the question was. -----Original Message----- From: Chris Edwards [mailto:chris.edwards@obinet.com] Sent: Thursday, May 08, 2003 10:08 AM To: php-general@lists.php.net Subject: Re: [PHP] Counter Either way... javascript nor java can accomplish it.... he said the file is counting without user intervention all day... the only way to create a counter that can do that is through a seperate process that is not connected to the web. cron can schedule a script to write to a file. how you get that information out of the file is up to you. a frame and some meta refresh is simple. can javascript read a file on the server? I think not. Can java, why? it takes to long to load. -- Chris Edwards Web Application Developer Outer Banks Internet, Inc. 252-441-6698 chris.edwards@obinet.com http://www.OuterBanksInternet.com ----- Original Message ----- From: <bbonkosk@tampabay.rr.com> To: "Chris Edwards" <chris.edwards@obinet.com>; <php-general@lists.php.net> Sent: Thursday, May 08, 2003 5:57 AM Subject: Re: [PHP] Counter > Yes, this could be done in PHP to, but isn't that like using a screwdriver to > pound in a nail?
