How Can I Determine the First and Last Day of the Week in PHP?

Determining the First Day of the Week in PHP

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

Step 1: Determine the Current Day of the Week

Use the date() function to get the current day of the week as a number from 0 to 6, where Sunday is represented by 0 and Monday by 1.

$day = date('w');

Step 2: Calculate Day of Previous Sunday

Subtract the current day of the week from the current date to get the date for the previous Sunday.

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

Step 3: Calculate Day of Subsequent Saturday

Add 6 days to the current date to get the date for the subsequent Saturday.

$week_end = date('m-d-Y', strtotime('+'.(6-$day).' days'));

Output:

The variables $week_start and $week_end now contain the date for Sunday and Saturday of the current week in MM-dd-YYYY format, respectively.
