I can't seem to get DateTime::createFromFormat()
to work in PHP 7.0.26
My code
date_default_timezone_set('America/New_York');
$t = '2018-02-23T11:29:16.434Z';
echo '$t: ' . json_encode($t) . PHP_EOL;
$f = DateTime::RFC3339_EXTENDED;
echo '$f: ' . json_encode($f) . PHP_EOL;
echo 'createFromFormat: ' . json_encode(DateTime::createFromFormat($f, $t)) . PHP_EOL;
echo 'getLastErrors: ' . json_encode(DateTime::getLastErrors()) . PHP_EOL;
$t = '2018-02-23T11:29:16.434+00:00';
echo '$t: ' . json_encode($t) . PHP_EOL;
echo 'createFromFormat: ' . json_encode(DateTime::createFromFormat($f, $t)) . PHP_EOL;
echo 'getLastErrors: ' . json_encode(DateTime::getLastErrors()) . PHP_EOL;
Output:
$t: "2018-02-23T11:29:16.434Z"
$f: "Y-m-d\\TH:i:s.vP"
createFromFormat: false
getLastErrors: {"warning_count":0,"warnings":[],"error_count":2,"errors":{"20":"The format separator does not match","21":"The timezone could not be found in the database"}}
$t: "2018-02-23T11:29:16.434+00:00"
createFromFormat: false
getLastErrors: {"warning_count":0,"warnings":[],"error_count":2,"errors":{"20":"The format separator does not match","21":"The timezone could not be found in the database"}}
I note that "v" is not listed in the values for the format parameter for DateTime::createFromFormat() -- but supposedly I should be able to use the const DateTime::RFC3339_EXTENDED
which includes a "v". It also says that this const was added in version 7.0
As CBroe noted, this is the right solution for you. You should use Y-m-d\TH:i:s.uP
instead of DateTime::RFC3339_EXTENDED
, which is Y-m-d\TH:i:s.vP
:
$date = DateTime::createFromFormat("Y-m-d\TH:i:s.uP", "2018-02-23T11:29:16.434Z"); //works
I actually went to take a look why this is happening, and here's what I found.
There is a closed bug requesting support for RFC3339 with milliseconds. The bug author created a pull request to add this feature. But whilst he created a RFC3339_EXTENDED
constant for the format
function, he did not add the support for createFromFormat
. If you take a look here, there is no support for v
option (which is milliseconds). So yeah.
Yes, apparently it only got fixed in PHP 7.3.0, see this https://3v4l.org/4nMi4
