php datetime createformat parse

Question

I'm trying to parse following string:

 Thu Oct 03 2013 07:03:41 GMT+0200 (Central Europe Standard Time)

But I'm struggling to find the corresponding format, I tried:

  $date= DateTime::createFromFormat('D M d Y H:i:s eO (*)','Thu Oct 03 2013 07:03:41 GMT+0200 (Central Europe Standard Time)');
  echo $date->format('Y-m-d');

Which results in error. Problem is, that there is no space between GMT+0200 and the brackets. Following works just fine

$date= DateTime::createFromFormat('D M d Y H:i:s e O','Thu Oct 03 2013 07:03:41 GMT +0200');
echo $date->format('Y-m-d');

But (obviously) I should be able to parse also the first example. So do you have any suggestion how the correct format should look like?

the error I get:

Fatal error: Call to a member function format() on a non-object in C:\....

var_dump of $date before calling $date->format:

 boolean false

what is the error you see? also, are you missing an apostrophe in --> e O',[here?]Thu Oct <--- — Jaak Kütt

The problem is the format string, which should be

D M d Y H:i:s e+

I have replaced eO with just e because the input contains GMT+0200, which does not have a separator between "GMT" and the offset. I have also replaced the (*) part with +, which is the only specifier that can consume a variable amount of input (* matches one token, i.e. one word -- if there is more input afterwards the parse fails).

Note that there will still be a warning due to the use of + (use DateTime::getLastErrors to see it), but the conversion will work correctly.

Could you link to the docs for the use of '+'. I'm probably missing something, but can't find anything atm.

@vascowhite: php.net/manual/en/datetime.createfromformat.php, bottom of the table.

You could split the incoming string. Here is one way of skinning this particular cat:-

$dateString = 'Thu Oct 03 2013 07:03:41 GMT+0200(Central Europe Standard Time)';
\DateTime::createFromFormat('D M d Y H:i:s O', explode('(', $dateString)[0]);

See http://php.net/date for more help.

See it working.

Yes, I was thinking about the same thing, but trying to avoid that solution :-)

@user1762087 I can appreciate that. However, this method does avoid generating the warning that Jon's method produces. However, if you are not checking DateTime::getLastErrors() for the warning then that won't be an issue for you.
