How to reverse date

Question

I’m trying to invert a date variable that displays the results like this:

2016/05/20

But I want a php function that displays like this:

20/05/2016

How to do this?

Answer 1

You can do that with the data() and the stringtotime() thus:

echo date("d/m/Y", strtotime("2016/05/20"));

Example: https://ideone.com/rzIRY0

Another option is to treat as a normal string, split with explode(), reverse the order with array_reverse() and merge into a string again with implode(). Then it would be something like this:

echo implode("/", array_reverse(explode("/", "2016/05/20")));

Answer 2

I already answered something similar a few days ago, in case I wanted to see the answer is on that topic ... and the concept is the same you should "break" your string in the "/" bars with the function "explode" and then put them back together with the function "implode", i used the function "array_reverse" to do the inversion, but as it is a date you could do it manually.

Example used inversion by PHP

<?php
// Sua data
$data = "2016/05/20";

// Quebra a data nos "/" e transforma cada pedaço numa matriz
$divisor = explode("/", $data);

// Inverte os pedaços da data (via PHP)
$reverso = array_reverse($divisor);

// Junta novamente a matriz em texto
$final = implode("/", $reverso);

// Imprime os resultados na tela
echo $final;
?>

Example inverting "manually"

<?php
// Sua data
$data = "2016/05/20";

// Quebra a data nos "/" e transforma cada pedaço numa variavel
list($ano, $mes, $dia) = explode("/", $data);

// Monta a data de volta no formato certo
$data_nova = ($dia . "/" . $mes . "/" . $ano);

// Imprime os resultados na tela
echo $data_nova;
?>

Answer 3

If you are programming in a procedural way an option is to use the function date_format:

$date = date_create("2016/05/08");
echo date_format($date,"d/m/Y");

If you are using the Object Orientation approach you can use format:

$data_string = '2016/05/08';
$data = new DateTime($data_string);
echo $data->format('d/m/Y');

But it is a question with n possible solutions.
