Using the following PHP date formats, you can get today's day relative to a week:
Character | Description |
---|---|
D |
A three-letter textual representation of a day (Mon through Sun ). |
l |
A full textual representation of the day of the week (Sunday through Saturday ). |
N |
ISO-8601 numeric representation of the day of the week (where 1 denotes Monday and 7 denotes Sunday). |
w |
Numeric representation of the day of the week (where 0 denotes Sunday and 6 denotes Saturday). |
For example:
$dt = new DateTime();
echo $dt->format('D'); // output: 'Mon' - 'Sun'
echo $dt->format('l'); // output: 'Monday' - 'Sunday'
echo $dt->format('N'); // output: 1 - 7
echo $dt->format('w'); // output: 0 - 6
Or, alternatively, you can achieve the same using the date()
function, like so:
echo date('D'); // output: 'Mon' - 'Sun'
echo date('l'); // output: 'Monday' - 'Sunday'
echo date('N'); // output: 1 - 7
echo date('w'); // output: 0 - 6
To include the timezone, you could do the following:
$tz = new DateTimeZone('Europe/Berlin');
$dt = new DateTime('now', $tz);
echo $dt->format('D'); // output: 'Mon' - 'Sun'
echo $dt->format('l'); // output: 'Monday' - 'Sunday'
echo $dt->format('N'); // output: 1 - 7
echo $dt->format('w'); // output: 0 - 6
You can achieve the same with the date()
function by setting the timezone using date_default_timezone_set()
. However, this isn't the ideal solution as it would set the default timezone globally (i.e. it will be used by all date/time functions). To avoid that, you should use the DateTime
object instead (as shown above).
