PHP day of week numeric to day of week text

Question

This may be really easy but I can\'t find a PHP function to do this...

OK so

$dow_numeric = date(\'w\');

gives the numeric day of t

Answer 1

This should work:

$dow_numeric = 3;

$last_sunday = strtotime('last Sunday');
$dow_text = date('D', strtotime('+'.$dow_numeric.' day', $last_sunday));

Answer 2

It's not popular, but there's actually a function jddayofweek for this in PHP. You can call it with the second parameter as 1 to get full gregorian week day name or 2 for the abbreviated name.

e.g. jddayofweek(2, 2); #returns Wed

Note that for this function, numbers start at Monday. So Monday=0, Tuesday=1, ...

Answer 3

If you need locale support you can use a bit improved function of Hamishs answer:

Example using german weekdays:

setlocale(LC_TIME, 'de_DE');
$dow_numeric = 3;
$dow_text = strftime('%A', strtotime("Sunday +{$dow_numeric} days"));

http://php.net/strftime

If $dow_numeric start on 0 (0 = Monday) you can just change Sunday to Monday or add $dow_numeric += 1

Answer 4

Bit of a hack, but:

$dow_text = date('D', strtotime("Sunday +{$dow_numeric} days"));

Answer 5

function getDay(){
    $dowMap = array('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday');
    $dow_numeric = date('w');
    return $dowMap[$dow_numeric];
}

Answer 6

To get Sunday to Saturday from numeric day of the week 0 to 6:

//For example, our target numeric day is 0 (Sunday):
$numericDay = 0; //assuming current date('w')==0 and date('D')=='Sun';

Solution-1: Using PHP's built-in function jddayofweek() which starts from Monday whereas date('w') starts from Sunday:

jddayofweek($numericDay-1, 1); //returns 'Sun', here decreasing by '-1' is important(!)

//jddayofweek(0, 1); //returns 'Mon';
//jddayofweek(0, 2); //returns 'Monday';

Solution-2: Using a trick(!):

date('D', strtotime("Sunday +{$numericDay} days")); //returns 'Sun';

//date('l', strtotime("Sunday +{$numericDay} days")); //returns 'Sunday';
