echo $day = date( code example

Example 1: date in php

FYI: there's a list of constants with predefined formats on the DateTime object, for example instead of outputting ISO 8601 dates with:

<?php
echo date('c');
?>

or

<?php
echo date('Y-m-d\TH:i:sO');
?>

You can use

<?php
echo date(DateTime::ISO8601);
?>

instead, which is much easier to read.

Example 2: name of today php

$datetime = DateTime::createFromFormat('YmdHi', '201308131830');
echo $datetime->format('D');

// or 

$date = new \DateTime();
echo $date->format("D");
