When I make projects on my website, I've saved the time and date that I made them on in MySQL as '2012-02-27 12:32:36' format.
How can I get this to display as:
"February 27, 2012 12:32 p.m."?
I've looked at other date formatting on PHP and read on the PHP website, but all of the functions they provide don't seem to be for grabbing a date in the format that I've saved it in.
First, convert the MySQL DateTime string you have into a DateTime object by using DateTime::createFromFormat()
$mysqlDateTime = '2012-02-27 12:32:36';
$date = DateTime::createFromFormat('Y-m-d H:i:s', $mysqlDateTime);
Then, simply call DateTime->format() with the desired format string:
$formattedDate = $date->format('F j, Y g:i a');
You can also use the MySQL UNIX_TIMESTAMP() date function (to extract a unix timestamp compatible with date()) or use strtotime(), however note that these methods do not support dates after January 19, 2038 on 32-bit systems due to overflow (the two methods do not support PHP's automatic number variables promotion).

I have a xml file, containing several dates, in this format: 2016-07-23T07:00:00.000Z. I'm using a php function to convert this in to a format for publishing on a website. This should actually result in something like Saturday, 24th of July (24th, not 23rd, because of the time offset. My function somehow ignores the T07:00:00.000Z part and thus returns Friday, 23rd of July. Can anybody help me out with the proper way to convert this date?
Thanks, Peter
The string in question
2016-07-23T07:00:00.000Z
is a W3C datetime format (W3C DTF) (Complete date plus hours, minutes, seconds and a decimal fraction of a second) which can be properly parsed incl. the fractions of a second with the date_create_from_format](http://php.net/date_create_from_format) function:
$originalDate = "2016-07-23T07:00:00.000Z";
date_create_from_format('Y-m-d\TH:i:s.uO', $originalDate);
It does create a new DateTime which then can be formatted with the for PHP standard codes, e.g.
date_create_from_format('Y-m-d\TH:i:s.uO', $originalDate)
->format('Y-m-d H:i:s'); # 2016-07-23 07:00:00
As that W3C format carries the timezone already and it is UTC, and you wrote you want a different one, you need to specify it:
date_create_from_format('Y-m-d\TH:i:s.uO', $originalDate)
->setTimezone(new DateTimeZone('Asia/Tokyo'))
->format('Y-m-d H:i:s');
The reason why this is not visible (and controlable with the code given) in the previous answer is because date formats according to the default set timezone in PHP where as each DateTime has it's individual timezone.
An equivalent with correct parsing (incl. decimal fraction of a second) with the other answers then is:
$dateTime = date_create_from_format('Y-m-d\TH:i:s.uO', $originalDate);
date('Y-m-d H:i:s', $dateTime->getTimestamp());
Hope this explains it a bit better in case you need the complete date value and / or more control on the timezone.
For the format, see as well: In what format is this date string?
$oldDateTime= "2016-07-23T07:00:00.000Z"; // Your datetime as string, add as variable or whatever.
$newDateTime= date("Y-m-d H:i:s", strtotime($originalDate));

I am using a plugin to create wordpress posts from a twitter feed, and I am trying to edit it so the published time is the same as the tweeted time, rather than the time the cron was run.
Unfortunately, twitter's API returns an already formatted date string, instead of a timestamp, so I am having to parse it and then save it in a wordpress friendly format.
// Wed Jun 06 20:07:10 +0000 2012 (Twitter formatted date example)
// 2014-03-10 18:30:26 (Wordpress formatted date example)
$tweet_date = $tweet->created_at;
$tweet_date = date_create_from_format("D M d h:i:s O Y", $tweet_date);
$tweet_date = date("Y-m-d h:i:s", $tweet_date);
Unfortunately, all I am getting from this the Unix Epoch (Jan 1st, 1970).
I know I must be missing a step, but I can't figure out where.
You had two issues:
1) You were using h for hours when you meant H for 24 hour periods
2) You need to use date_format() when using date_create_from_format() as that function returns a DateTime object which is not compatible with date()
$tweet_date = date_create_from_format("D M d H:i:s O Y", 'Wed Jun 06 20:07:10 +0000 2012');
echo date_format($tweet_date, 'Y-m-d H:i:s');
See it in action
The problem is because you're mixing and matching between PHP's old and new-style date handling.
date_create_from_format() is part of the newer API, and outputs a DateTime object, not the timestamp integer that the older date() function is expecting.
Ideally you should stick entirely with either the new or the old date functions. You can switch between them, but there usually isn't a need to.
For example, in your case, the DateTime object generated by date_create_from_format() has a perfectly usable format() method attached to it, which does exactly the same as the date() function, but on a DateTime object.
$tweet_date_object = date_create_from_format("D M d h:i:s O Y", $tweet_date);
$tweet_date = $tweet_date_object->format("Y-m-d h:i:s");
I have date and time stored in my database as MySQL DATETIME datatype. While inserting into the database, I am using the following PHP variable
$serverTime = strftime("%Y-%m-%d %H:%M:%S",$_SERVER['REQUEST_TIME']);
A sample DATETIME stored in database is: 2011-11-26 01:00:27
Now my website needs the date to be displayed in the following format: November 26, 2011 (time is not required)
How can I do it? I am trying the below in PHP but wrong output I am getting.
echo strftime("%B %d, %Y",$serverTime)
The PHP strftime() function wants input to be a 32-bit integer timestamp, which is the number of seconds since 1970-01-01 00:00:00.
The default output format for MySQL datetime is YYYY-MM-DD HH:MM:SS. When you use this string in PHP, the leading digits are converted into the integer 2011, which is interpreted to be within the first hour of 1970-01-01.
So you must fetch the datetime from MySQL in another format. Choices:
UNIX_TIMESTAMP(datetime_column) to fetch the datetime as an integer that you can give to PHP's strftime() function.
DATE_FORMAT('datetime_column', '%M %d, %Y') to format the datetime as a string, and then you don't have to use strftime() to format it.
While I would recommend a completely SQL approach, you can use PHP's DateTime class to process your string in PHP (assuming you're running PHP > 5.3):
// Pick a valid TimeZone
$date_obj = DateTime::createFromFormat( 'Y-m-d H:i:s', '2011-11-26 01:00:27', new DateTimeZone( 'America/New_York'));
echo $date_obj->format('F d, Y');

i have 2011-08-03 21:56:41 coming from a MySQL timestamp and I would like to convert it to Wednesday August 3rd, 2011 using PHP (Not MySQL). How can this be done?
Use strtotime() to convert your date/time string to a Unix timestamp so you can use date() to format the value of that timestamp any way you want.
$stamp = '2011-08-03 21:56:41';
echo date('l F jS, Y', strtotime($stamp));
// output: Wednesday August 3rd, 2011
The reference at the date() manual page is extremely useful. I still reference it all the time for the list of special format characters.
The strtotime() function sort of seems like magic at first. For future reference, here's the supported date/time documentation on what input formats strtotime() can accept.
