    The get_weekstartend() function in WordPress is designed to calculate the start and end of a week based on a given date or datetime string from MySQL. This is particularly useful for applications where you need to organize data or events on a weekly basis.

    Function Definition

    get_weekstartend( string $mysqlstring, int|string $start_of_week = '' ): int[]
    

    Parameters

    1. $mysqlstring (string, required): This is the date or datetime field type from MySQL. The string should represent a date in a format that MySQL recognizes.

    2. $start_of_week (int|string, optional): This defines the start of the week. It's an integer where 0 (Sunday) through 6 (Saturday) represents the days of the week. The default value is an empty string '', which means it will use the start of the week as defined in WordPress settings.

    Return

    The function returns an array of two integers:

    • start: The week's start date as a Unix timestamp.
    • end: The week's end date as a Unix timestamp.

    Sample Usage

    Here's an example of how you might use get_weekstartend():

    // Assume $date_string is a date or datetime string from MySQL
    $date_string = '2024-01-15'; // For example, 15th January 2024
    
    // Optionally, you can specify the start of the week
    // For example, 1 for Monday
    $start_of_week = 1;
    
    // Get the start and end of the week
    $week_limits = get_weekstartend($date_string, $start_of_week);
    
    // Extracting the start and end dates
    $week_start = $week_limits['start'];
    $week_end = $week_limits['end'];
    
    // Optionally, convert the Unix timestamps to a readable format
    echo 'Week Start: ' . date('Y-m-d', $week_start) . "\n";
    echo 'Week End: ' . date('Y-m-d', $week_end) . "\n";
    

    In this example, $date_string represents a date from a MySQL database. The function will calculate the start and end of the week in which this date falls. If $start_of_week is specified, the function will use this value to determine the first day of the week; otherwise, it will default to the WordPress setting. The function then returns the start and end dates of the week as Unix timestamps, which can be formatted into a more readable date format using PHP's date() function.
