Return dates of current calendar week as array in PHP5

Question

How would I put together a PHP5 function that would find the current calendar week and return the dates of each day in the week as an array, starting on Monday? For example,

Answer 1

Lessee. . First, to avoid any timezone issues I'd peg to noon on the day you want to compare against, so an hour either way won't cause any problems.

$dateCompare = time(); // replace with a parameter
$dateCompare = mktime(12, 0, 0, date('n', $dateCompare), 
      date('j', $dateCompare), date('Y', $dateCompare));

Then find the day of week of your date.

$dow = date('N', $dateCompare);

1 is Monday, so figure out how many days from Monday we are.

$days = $dow - 1;

Now subtract days worth of seconds until you get back to Monday.

$dateCompare -= (3600 * 24 * $days);

Now assemble your array of days.

$output = array();
for ($x = 0; $x < 7; $x++) {
    $output[$x] = $dateCompare + ($x * 24 * 3600);
}

This is an array of timestamps, but you could store the dates as strings if you prefer.
