Okay, this is the problem....theres a matrix of 0's and 1's taht correspond the time slots and the days of the week on whether you can work or not during the time block. If it's a 1, you can work, if it's a 0, you're unavailable.

I'm trying to set it up for sunday first so I can apply it to the rest of the week, and the method for sunday will apply to mon-sat.

The time blocks are these:
8:00-9:15am => X1
9:45-11:00am => X2
11:15-12:30pm => X3
1:00-2:15pm => X4
2:30-3:45pm => X5
4:25-5:30pm => X6
6:30-7:45pm => X7
8:15-9:30pm => X8

Now, what I'm trying to do is, say you have 1's at x1, x2, x3, and x6, x7, x8, but 0's at x4, and x5.

so you can work from 8:00-12:30, and 4:25 - close.

How can I setup some loops....or something, to make it say that?

My current code:

PHP Code:

$sun=1;
while($sun <= 50)
{
    if($hours[$sun] == 1)
    {
        switch($sun)
        {
        case 1:
        $_SESSION['aSundayHours'] .= '8:00-9:15 am, ';
        break;
        case 8:
        $_SESSION['aSundayHours'] .= '9:45-11:00 am, ';
        break;
        case 15:
        $_SESSION['aSundayHours'] .= '11:15-12:30 pm, ';
        break;
        case 22:
        $_SESSION['aSundayHours'] .= '1:00-2:15 pm, ';
        break;
        case 29:
        $_SESSION['aSundayHours'] .= '2:30-3:45 pm, ';
        break;
        case 36:
        $_SESSION['aSundayHours'] .= '4:25-5:30 pm, ';
        break;
        case 43:
        $_SESSION['aSundayHours'] .= '6:30-7:45 pm, ';
        break;
        case 50:
        $_SESSION['aSundayHours'] .= '8:15-9:30 pm, ';
        break;
        }
    }
    $sun = $sun + 7;
} 


But that will output:

8:00-9:15 am, 9:45-11:00 am, 11:15-12:30 pm, 4:25-5:30 pm, 6:30-7:45 pm, 8:15-9:30 pm,

I guess my main questions, is what's the best way to have a string of 1's and 0's and finding the groups of 1's and classifying them. Any questions, please ask, and any help is awesome!!!

You have the times and their respective 1 or 0 in an array, right? Then you could probably just go thru them all in a loop, and when you find a time with a 1 you select it's starting time and store it in a variable $start, the same thing for it's ending time, in $end.

Then keep looping and if the next time also has a 1, simply change $end to the new ending time. If the next time also has 1, change $end again and so on. Now, if you put $start and $end in an array instead, like

PHP Code:

array(array('start', 'end'), array('start', 'end'), ...) 


you can store several start's and end's.

Well, the only problem is I need to apply this practically to a scheduling system. And something dawned on me...what if I use military time?

That way the start and end time will always be different, and for the schedule, I can check to see if the time their needed is between their available slots.
