Answer 1

Are you assuming Sunday is day of the week number 1 ? And Saturday 7 ?

If so, Sunday is 7 and Saturday 6 . So your code would look like this:

$dt = strtotime(date('Y-m-d'));

$res['start'] = date('N', $dt) == 7 ? date('Y-m-d', $dt) : date('Y-m-d', strtotime('last sunday', $dt));

$res['end'] = date('N', $dt) == 6 ? date('Y-m-d', $dt) : date('Y-m-d', strtotime('saturday', $dt));

$day_of_week = date('N', strtotime($res['start']));


$given_date = strtotime($res['end']);

$first_of_week =  date('Y-m-d', strtotime("- {$day_of_week} day", $given_date));

$first_of_week = strtotime($first_of_week);

for ($i = 1 ; $i <= 7; $i++) {
    $datess[] = date('Y-m-d', strtotime("+ {$i} day", $first_of_week));

    $week_array[] = date('m/d', strtotime("+ {$i} day", $first_of_week));
    print_r($datess);
}

One solution using PHP powerful date functions time date and strtotime

<?php

if (date('D') == 'Sun') {
    $lsTimestamp = time();
} else {
    $lsTimestamp = strtotime('last Sunday');
}

$dates = [date('Y-m-d', $lsTimestamp)];
for ($i = 1; $i <= 6; $i++) {
    $dates[] = date('Y-m-d', strtotime('+' . $i . ' day', $lsTimestamp));
}

var_dump($dates);
