Carbon parse to ISO8601

I am trying to get the current time and format it like:

"2018-09-26T21:40:29+02:00"

But when I try:

$isoDate = CarbonCarbon::now()->format('c');

as I understood passing a c to format function will parse it to iso8601 but clearly thats not the case.

Any help on how to parse current time to ISO8601 OR 20181001T094006Z

Answer

There is no single 8601 format. 8601 defines various acceptable formats, of which PHP’s c represents one of the most common forms.

There is no single character for the specific 8601 format you wish but a format of YmdTHisZ should work. T and Zare literal, so escape them with a backslash to avoid them being interpreted in the format string. Be sure that only UTC timestamps are used with this particular format.

http://php.net/manual/en/function.date.php lists all the acceptable format characters.
