Does the PHP Datetime class support the creation of dates in the Brazilian format?

Question

In the code below echo be printing +273 days, but the right one wouldn’t be +9 days?

$datetime1 = new DateTime('01/04/2018');
$datetime2 = new DateTime('10/04/2018');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days');

I don’t understand why, could you help me? Thanks in advance

Answer 1

YES, SHE SUPPORTS.

To format in DD MM AAAA you can use -, . and \t, but not /:

$datetime1 = new DateTime('01-04-2018'); // poderia ser 01.04.2018 também
$datetime2 = new DateTime('10-04-2018');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days');

See working on IDEONE

Answer 2

You can format the time in several ways by manipulating this object Datetime. The documentation of this php method brings numerous ways to do it.

But as the question refers to the Brazilian format here goes:

$datetime2 = new DateTime('2011-01-01');
var_dump($datetime2->format('d/m/y'));

Exit: string(8) "01/01/11"

Another example:

$datetime1 = new DateTime('2011-01-02');
var_dump($datetime1->format('d*m*y'));

Exit: string(8) "02*01*11"

Make sure the time entered is in the pattern: ('ano-mes-dia'). If no strange things will happen.

Now with the data in perfect order apply your methods:

$interval = $datetime1->diff($datetime2);

echo $interval->format('%R%a days');

Exit: 1
