Convert string to Date time

Question

I am developing a Portable application where there is a Rest Api that needs to send some values, one of them being a datetime. Access Models with the following command:

['registerDate' => $anuncio->created_at]

I happen to be returned the following amount:

    Carbon @1536805969 {#461 ▼
  date: 2018-09-12 23:32:49.0 America/Sao_Paulo (-03:00)
}

In the application documentation that will receive the data specifies that I need to send the data in json like this:

"registerDate": "2017-10-27T13:09:22.780Z",

I made a function that handles the data returned by Carbon:

$date = (
    implode(' ', array(
        explode(' ', $anuncio->created_at)[0], 
        explode(' ', $anuncio->created_at)[1])));

That returns the string:

"2018-09-12 23:32:49"

But the documentation specifies that the format should be datetime. Does anyone know any function or way to get the date in the requested format?

Answer 1

You probably need to do something about it:

<?php

$a = "2018-09-12 23:32:49.0 America/Sao_Paulo (-03:00)";
$dt = new DateTime("2018-09-12 23:32:49");
echo $dt->format('Y-m-d\TH:i:s.Z\Z');

Take a look at the documentation on date formatting.
