Get Start and End Days for a Given Week in PHP

Question

I\'m trying to get the week range using Sunday as the start date, and a reference date, say $date, but I just can\'t seem to figure it out.

For example,

Here's my version, which uses a similar notion to Clay's:

/**
 * Start of the week
 *
 * 0 = Sun, 1 = Mon, etc.
 */
define( 'WEEK_START', 0 );

/**
 * Determine the start and end dates for
 * the week in which the specified date
 * falls
 *
 * @param $date Date in week
 * @param $start Week start (out)
 * @param $end Week end (out)
 */
function week_bounds( $date, &$start, &$end ) {
    $date = strtotime( $date );
    // Find the start of the week, working backwards
    $start = $date;
    while( date( 'w', $start ) > WEEK_START ) {
        $start -= 86400; // One day
    }
    // End of the week is simply 6 days from the start
    $end = date( 'Y-m-d', $start + ( 6 * 86400 ) );
    $start = date( 'Y-m-d', $start );
}

Lightly tested. Code may not be bulletproof, or handle dates in the far past or future. Use at your own risk. Do not immerse the code in water.
