calendar cycles

[zzz]

How do I pick a date and start a cycle that will go through the year.

Let's say I name the days of the cycle:

$cycle = array('red', 'blue', 'green', 'yellow', 'black');

Then I pick a date, say January 29 to be the first day of the cycle. So it'll be something like:

Jan.29 - red
Jan.30 - blue
Jan.31 - green
Feb.1 - yellow
Feb.2 - black
Feb.3 - red
Feb.4 - blue

and so on from picked date on. How do I do that?

Use a while or for loop. And since you are using and array you can use the arrays indexing to get the color. And then the while loop can increment forward each time the loop is ran. And for each value have a variable that is set. And when it reaches the max value have it reset to 0.

$i = 0;
while ($date != "") {

 $colorvar = $cycle[$i];

 if ($i == 4) {
      $i = 0;
 }
 else {
      $i++;
 }
}

That is a basic idea your particulars may vary it some.

OK, I'll try that, but I'm still a bit uneasy how do I anchor the beginning date and if I come to the script how would it calculate where in the cycle I am at the moment?

Both those question really depend on what your script is and it is doing as well as what its output is.

I can't even begin to give an answer. For every general usage I think of 5 variations, I could go on indefinitely explaining the different ways to do this. My most recent calendar script was 358 lines of code. For me I know exalt were to start the loop and were to end it but those 2 spots are almost 100 lines apart. For you it may be only 20 lines and the next guy it could be 500.

Most likely that while loop will need to be in an if/else

if ($date >= $submiteddate) {
     // run loop
}
else {
     //do something else
}

You have to write your code so that when looping through the days on the calendar when that loop reaches the date you want the colors to start on is starts running that loop.
