Can anyone help me with a timer?

Hello, i've just learned basic PHP for this script I needed for my page. Im pretty much finished, except for the most important aspect.

I need one of my variables to increase by 1 every day at a cirtain time automatically (Or have a timer increase it every 24 hours)

Any help would be much apreciated, thanks

Have a variable increase every day at a certain time? Is this a script you are running from a command line and it runs in a constant loop? If not, variables get reset every time a script is run.

Explain what exactly you are trying to accomplish here and I'm sure we can figure something out...

ok i dont really know what im doing. I will explain what im trying to do.

Im starting up a little web comic, and im writing an uptator script for it. So far what it does is it makes next/previous buttons work, adds the apropriate image for each day, and when it gets to the $today value, it stops going forward. So of course I $today to increase by 1 value every day so that it updates automatically. I assumed this could be done in PHP... If not does anyone have any other suggestions?

I wouldn't try to increase the variable each day. Instead, I'd rely on the date() function.
For example, you could create an array and use a while loop, and then populate the array based on date. First name your comics for each day, like this:

comic0425.jpg
comic0426.jpg
etc...

Then, if the comic array is called "comicarray,":

---------------------------------
$day = date("d"); //gets day
$month = date("m"); //gets month
$inserter = "1"; //pace variable
while ($inserter <= $day) {
//sets name of comic
$add = "comic" . $month . $day . ".jpg";
//adds comic to array
$comicarray[] = $add;
//increase pace, runs again
$inseter++; }

----------------------------
now you have array to work with. And you can echo each item of the array as a link or as an image...

ah! I didnt even know about the date() function (Like i said i really dont know what im doing)

Thank you very much for your help, i will experiment and get it working now i think =)
