There's a bug report that exactly describes your problem :)

<a href="https://bugs.php.net/bug.php?id=51950" rel="noreferrer">https://bugs.php.net/bug.php?id=51950</a>

Since 2016-08-07, the bug report has been marked as "not a bug". You need to use <code>strtotime</code> or <code>new DateTime</code> instead.

The constants that have been defined apply to both formatting and parsing in the same way, which forces your ways.

It is very strange and disappointing that this bug is still actual.
Here is a right pattern for parsing date with microseconds in decimal part of seconds:

<pre><code>Y-m-d\TH:i:s.uO
</code></pre>

Usage:

<pre><code>$dateStr = '2015-04-29T11:42:56.000+0400'
$ISO = 'Y-m-d\TH:i:s.uO'
$date = DateTime::createFromFormat($ISO, $dateStr)

Nobody mentioned to use DATE_ATOM which is as far as i know phps most correct implementation of ISO 8601. It should at least work for the last 3 of these:

<pre><code>&lt;?php

$dates = array(
 "2010-12-07T23:00:00.000Z",
 "2010-12-07T23:00:00",
 "2010-12-07T23:00:00Z",
 "2010-12-07T23:00:00+01:00",
 (new \DateTime("now"))-&gt;format(DATE_ATOM)
);

foreach($dates as $d) {

 $res = \DateTime::createFromFormat(DATE_ATOM, $d);

 echo "try $d: \n";
 var_dump($res);
 echo "\n\n";
}

?&gt;
</code></pre>

To be able to parse all of them i wrote a tiny function:

<pre><code>&lt;?php

function parse_iso_8601($iso_8601_string) {
 $results = array();
 $results[] = \DateTime::createFromFormat("Y-m-d\TH:i:s",$iso_8601_string);
 $results[] = \DateTime::createFromFormat("Y-m-d\TH:i:s.u",$iso_8601_string);
 $results[] = \DateTime::createFromFormat("Y-m-d\TH:i:s.uP",$iso_8601_string);
 $results[] = \DateTime::createFromFormat("Y-m-d\TH:i:sP",$iso_8601_string);
 $results[] = \DateTime::createFromFormat(DATE_ATOM,$iso_8601_string);

 $success = array_values(array_filter($results));
 if(count($success) &gt; 0) {
 return $success[0];
 }
 return false;
}

// Test
$dates = array(
 "2010-12-07T23:00:00.000Z",
 "2010-12-07T23:00:00",
 "2010-12-07T23:00:00Z",
 "2010-12-07T23:00:00+01:00",
 (new \DateTime("now"))-&gt;format(DATE_ATOM)
);

foreach($dates as $d) {

 $res = parse_iso_8601($d);

 echo "try $d: \n";
 var_dump($res);
 echo "\n\n";
}

?&gt;
</code></pre>

As @Glutexo mentioned it works only if there are only 1 to 6 precision digits for the decimal part, too. Feel free to improve it.

For the answer listed here <a href="https://stackoverflow.com/a/14849503/2425651">https://stackoverflow.com/a/14849503/2425651</a>
we can use this format "Y-m-d\TH: i: s.u+" to keep the microseconds.

<pre><code>$format = 'Y-m-d\TH:i:s.u+';
$value = '2017-09-21T10:11:19.026Z'; // jsDate.toUTCString();

Use <code>DATE_ATOM</code> rather than <code>'c'</code> when formatting like @Steven said. This is how you work with ISO 8601 in PHP.

<pre><code>&lt;?php
$now_date = new DateTime();
$now_iso_8601 = $now_date-&gt;format(DATE_ATOM);
echo "Now in ISO 8601 format: {$now_iso_8601}\n";
$date_from_string_and_format = date_create_from_format(DATE_ATOM, $now_iso_8601);
echo "ISO 8601 formatted string, back to DateTime object:\n";
var_dump($date_from_string_and_format);
</code></pre>

prints

<pre><code>Now in ISO 8601 format: 2018-09-05T08:17:35-10:00

 return $t;

here are all supported dates

PHP DateTime::createFromFormat doesn't parse ISO 8601 date time
