php - How to get weeks starting on sunday?

Question

I need to get week number in php where week should be calculated from sunday. By default its from monday. Please help me to find a way how to get week number considering sunday as starting day.

In php manual ISO-8601 week number of year, weeks starting on Monday (added in PHP 4.1.0)

But I need to get week number of year, weeks starting on sunday.

thanks

Answer 1

Try this:

$week = intval(date('W'));

if (date('w') == 0) {            // 0 = Sunday
   $week++;
}

echo $week;

Not sure if the logic is right though;
