How to Retrieve the First Day of the Week in PHP

Determining the first day of the week can be essential for date-related applications. In PHP, this task can be effortlessly accomplished using built-in date functions.

Method:

To retrieve the first day of the week for a given date in MM-dd-yyyy format, follow these steps:

1. Determine the Day of the Week:

   • Use date('w') to retrieve the day of the week as a number (0-6), where 0 represents Sunday and 6 represents Saturday.

2. Calculate the First Day of the Week:

   • Use strtotime('-'.$day.' days') to subtract the day of the week from the current date. This will give you the date for the previous Sunday.

3. Format the Result:

   • Use date('m-d-Y') to format the result as mm-dd-yyyy.

Example Code:

The following code demonstrates how to implement the above method:

$day = date('w');
$week_start = date('m-d-Y', strtotime('-'.$day.' days'));

The variable $week_start will now hold the date for the previous Sunday, which is the first day of the current week.

Additional Notes:

• The resulting date will be in the locale's timezone.
• To obtain the first day of the current week, replace '-'.$day.' days' in the above code with '0 days'.
