[SOLVED] Grabbing all Mondays in a date range into array

[knox203]

Hey everyone, I have a script I found online that does exactly what I need it to do... but doesn't seem to be working for me when I try to print out the array. Can anyone point out what I'm doing wrong? Here's the code:

  <?
/**
* Function used to find the dates of specific days between
* two different dates.  So, if you want to find all the
* mondays and all the wednesdays between 2 dates, this
* function is right for you.
*
* @param string $startDate e.g. 2007-01-31
* @param string $endDate e.g. 2007-12-31
* @param csv string $days e.g. 'Su,M,T,W,TH,F,S';
* @return array
*/

$startDate = '2008-08-28';
$endDate = '2008-10-09';
$days = 'Mon';

function getDaysBetween($startDate, $endDate, $days)
{
    $days = explode(',', $days);
    $dates = array();
    foreach($days as $day)
    {
        $newDate = $startDate;
        switch ($day){
            case 'Su':
            case 'Sun':
                $day = 'Sun';
                break;
            case 'M':
            case 'Mon':
                $day = 'Mon';
                break;
            case 'T':
            case 'Tu':
            case 'Tue':
                $day = 'Tue';
                break;
            case 'W':
            case 'Wed':
                $day = 'Wed';
                break;
            case 'Th':
            case 'Thu':
            case 'Thur':
                $day = 'Thu';
                break;
            case 'F';
            case 'Fri';
                $day = 'Fri';
                break;
            case 'S':
            case 'Sat':
                $day = 'Sat';
                break;
            default:
                continue 2;
        }
        $curtime = strtotime("next $day", strtotime($startDate));
        $endtime = strtotime($endDate);
        while($curtime <= $endtime)
        {
           $dates[] = date('Y-m-d', $curtime);
           $curtime = strtotime("next 2 $day", $curtime);
        }
    }

    $dates = array_unique($dates);
    sort($dates);
    return $dates;
}
?>

 

And I'm using

<? print_r($dates); ?>

to print out the array.

You have to actually call the function.  Naming your variables the same as the parameters doesn't do anything. =P

Ahhh, that's why I love not paying for this site... I can feel like an idiot free of charge!! 

 

... Could you clear up this whole calling the function ordeal for a noobie?

 

Thanks!

Put this line after the function code and stuff. =P

 

$dates = getDaysBetween($startDate, $endDate, $days);

 

That only works because you have the variables set.

Thanks so much Dark!
