Question

With get the date of the first day of the week and last day of the week in php, first day Monday and the last day Friday, for example I have the date 2017-05-23 and I want to know the Monday one 2017-05-22 and the last one that would be 2017-05-26

date now = '2017-05-23'
first day of week = '2017-05-22' (Monday)
last day of week = '2017-05-26' (Friday)

Can I do this using date?

Answer 1

Something like this:

$mon = $fri = new DateTime('2017-05-23');
$mon->modify('Last Monday');
$fri->modify('Next Friday');
var_dump($mon);
var_dump($fri);

Answer 2

$the_date = '2017-05-23';
$the_day_of_week = date("w",strtotime($the_date)); //sunday is 0

$first_day_of_week = date("Y-m-d",strtotime( $the_date )-60*60*24*($the_day_of_week)+60*60*24*1 );
$last_day_of_week = date("Y-m-d",strtotime($first_day_of_week)+60*60*24*4 );

echo $first_day_of_week;
echo "~";
echo $last_day_of_week;

Answer 3

there is a solution but I'm not sure if you will accept it like this

$First_date = date_create('this week')->format('Y-m-d H:i:s');
$Last_date = date_create('this week +4 days')->format('Y-m-d H:i:s');
echo $First_date;
echo $Last_date;

Answer 4

My solve,

$datenow = date('Y-m-d');// date now
$mon = new DateTime($datenow);
$fri = new DateTime($datenow);
$mon->modify('Last Monday');
$fri->modify('Next Friday');

using echo

echo 'Monday: '.$mon->format('Y-m-d').'<br>';
echo 'Friday: '.$fri->format('Y-m-d').'<br>';

using var_dump()

var_dump($mon);
var_dump($fri);
