I need to convert a date string in a format like bellow using PHP,
2015-07-30T08:05:00.917Z
I try to convert using the bellow code,
echo str_replace('+00:00', '.917Z', gmdate('c', strtotime('2016-04-05 00:00:00')));
This will create 2016-04-05T00:00:00.917Z This is not correct,Is there any function to create date like this format?

Answer 1

There are two ways to create date from String.
1. date_create_from_format
$date=date_create_from_format("DATE_FORMAT",$dateString);
2. $date=new DateTime();
$date=$date->createFromFormat("DATE_FORMAT", $dateString);
Using following link to get your DATE_FORMAT.

Answer 2

You can do it as #Alok has mentioned in his answer.
Or similarly using the following code.
$date = DateTime::createFromFormat('U.u', microtime(TRUE));
echo $date->format('Y-m-d\TH:i:s.u\Z');
Note that the microsecond mentioned in your question is of 3 digits. But generally php date formatting outputs microseconds in 6 digits precision.
Like the above code outputs 2016-04-06T09:24:50.830000Z
So I think you have to do some hack there if the digit precision is important.

Answer 3

Pass it through the function formatTime. This creates a new DateTime object in PHP called $date that can also easily be manipulated if you need. The examples below formats the date in two different ways, both work.
Procedural Style:
function formatTime($millis) {
$date = new DateTime($millis);
return date_format($date, 'l, jS F Y \a\t g:ia');
}
Object Oriented Style:
function formatTime($millis) {
$date = new DateTime($millis);
return $date->format('l, jS F Y \a\t g:ia');
}
The format for date can be found at this link:

Hope this helps.
