Question

I am constructing a diary that has weekly views which I thought I had cracked because the dates seemed to appears as correct. It wasn’t until my MySQL queries kept returning what seemed like random results that I realized the the month is actually being seen as the day instead.

$week_number = date("W");
$year = date("Y");

for ($day=0; $day<=6; $day++) {
    $daily_date = date('d/m/Y', strtotime($year."W".$week_number.$day))."\n";
    $StartDate = date('d', strtotime($daily_date));
}

echo $starteDate;

$startDate returns the number of the month rather than the day and sure enough date('m', strtotime($daily_date)) returns the day rather than the month.

I can’t understand where I have made this silly mistake so any help would be appreciated.

Answer 1

This is because of the Americanisation of dates – strtotime will read the date as m/d/Y rather than d/m/Y.

The ISO for dates is Y-m-d and for ease I would use this format when doing any kind of date manipulation.
