Answer 1

Something like this should work fine:

<?php
    $startDateUnix = strtotime('2012-01-01');
    $endDateUnix = strtotime('2013-01-01');

    $currentDateUnix = $startDateUnix;

    $weekNumbers = array();
    while ($currentDateUnix < $endDateUnix) {
        $weekNumbers[] = date('W', $currentDateUnix);
        $currentDateUnix = strtotime('+1 week', $currentDateUnix);
    }

    print_r($weekNumbers);
?>

DEMO.

Output:

Array
(
    [0] => 52
    [1] => 01
    [2] => 02
    .........
    [51] => 51
    [52] => 52
)
