How to display weekly date between two dates?

Dear friends,

I need a php script/page that will take two dates (mm/dd/yyyy) value from form field and display all weekly dates between two dates.

(You do not need to create the input form, just take the value directly in php/javascript code like bellow).

The calculation will be for 1 year from $annualStartDate

Suppose,
$countType = "weekly"; // It can be (weekly, biweekly, monthly, quarterly)
$annualStartDate = "01/01/2011";
$annualEndDate = "12/31/2011"; // one year based on $annualStartDate
$countStartDate = "01/14/2011";

If $CountType = "weekly" then the output will be like bellow after pressing "Calculate" button:

Line Date Day
------------------
1 14-Jan-2011 Friday
2 21-Jan-2011 Friday
3 28-Jan-2011 Friday
- - - - - - - - - - - - -
Continue
- - - - - - - - - - - - -
51 30-Dec-2011 Friday

Please see the attached image.



I wish you will help me like previous. thank you

 

$countType = "weekly"; // It can be (weekly, biweekly, monthly, quarterly)
$annualStartDate = "01/01/2011";
$annualEndDate = "12/31/2011"; // one year based on $annualStartDate
$countStartDate = "01/14/2011";


$countInterval = array('weekly' => '+1 week', 'biweekly' => '+2 weeks', 'monthly' => '+1 month', 'quarterly' => '+3 months');

$i = 1;
$date = strtotime($countStartDate);
do {
    echo $i .' '. date('d-M-Y l', $date) .'<br />';

    $date = strtotime($countInterval[$countType], $date);

    $i++;
} while ( strtotime($annualEndDate) >= $date );

Dear babushkyn,

I am speechless, what I will say!!
YOU ARE ROCK, YOU ARE BOSS, YOU ARE AMAZING, YOU ARE ....YOU ARE .... YOU ARE ALL....
Thank You, Thank You, Thank You
Your quick solution is 100% ok.
Also thanks DigitalPoint to bring you here. I am proud of you found on this forum.

I solved this another way using strtotime and for loop. But when I got your solution I think it is better than me and professional looking.

May I know how old are you, where you from, what do you do?

Please take my thanks again from the core of my heart.
