    Date and Time issues

    Hey all,

    Okay, I have a problem -
    I have links from MONDAY to FRIDAY... and when the user clicks on the link it will send the script a value of 1-5

    1 through 5 equals mon,tue,wed,thr,fri...

    Now my problem is I need to take that 1-5 and convert it to the DAY its on.

    Meaning, today is Saturday(23rd) if they click Monday(Happends to be xmas) it woudl show the date 25th.

    Anybody know how I can do this? or a better way to do it?

    Here is some code to do this (tested) -
    PHP Code:

    "Today's day of the week is: $today_day_number (0=Sun, 1=Mon...)";
    "<br />";

    // test loop for possible values 1-5
    // $test_value is simulating the value received as input from the form

    for($test_value=1$test_value <=5;$test_value++){

    // if today_day_number is 6 (sat) - make this -1 so difference math works
    if($today_day_number == 6)
    $today_day_number = -1;

    // if test value (1-5) is greater than or equal to today_day_number, then test value is today or higher (coming week or current week)
        // if test value (1-5) is less than today_day_number, day entered has already gone past and is actually the following week (add 7)

    if($test_value >= $today_day_number)
    $difference $test_value-$today_day_number;
        } else {
    $difference $test_value-$today_day_number+7;
    "Test value: $test_value, Difference: $difference, date: ";
    date("d",mktime(000date("m")  , date("d")+$differencedate("Y"))); // mktime correctly does the math and wraps to the next week/month/year as needed
    echo "<br />";
    // end of test loop for possible values 1-5
    I actually tested this within another loop to simulate all the possible values for $today_day_number (0-6) and it looks like it works correctly.
    If you are learning PHP, developing PHP code, or debugging PHP code, do yourself a favor and check your web server log for errors and/or turn on full PHP error reporting in php.ini or in a .htaccess file to get PHP to help you.
