Determining Week Number for a Specific Day in a Given Month using PHP

In PHP, determining the week number for a specific day in a given month has been a challenging task for many developers. Here's how you can achieve this:

The "getWeeks" function takes two parameters: the date in YYYY-MM-DD format and the day on which the week rolls over. It calculates the number of days elapsed since the first day of the month, and then iterates through each day to determine the day of the week.

Once the function finds a day that matches the specified rollover day, it increments the week count. Finally, it returns the week number for the given date.

For example, the following code snippet retrieves the second week of June 2011, where the week rolls over on Sunday:

echo getWeeks("2011-06-11", "sunday"); //outputs 2
