   Returns a new DateTime object representing the date and time specified by the
   datetime string, which was formatted in the given
   format.
  
formatThe format that the passed in string should be in. See the formatting options below. In most cases, the same letters as for the date() can be used.

| y | A two digit representation of a year (which is assumed to be in the range 1970-2069, inclusive) | Examples: 99or03(which will be interpreted as1999and2003, respectively) |

| Full Date/Time | --- | --- | 
| U | Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) | Example: 1292177455 | 
| Whitespace and Separators | --- | --- | 
|  (space) | One space or one tab | Example:   | 
| # | One of the following separation symbol: ;,:,/,.,,,-,(or) | Example: / | 
| ;,:,/,.,,,-,(or) | The specified character. | Example: - | 
| ? | A random byte | Example: ^(Be aware that for UTF-8
          characters you might need more than one?.
          In this case, using*is probably what you want
          instead) | 
| * | Random bytes until the next separator or digit | Example: *inY-*-dwith
          the string2009-aWord-08will matchaWord | 
| ! | Resets all fields (year, month, day, hour, minute, second,
          fraction and timezone information) to zero-like values ( 0for hour, minute, second and fraction,1for month and day,1970for year andUTCfor timezone information) | Without !,all fields will be set to the
          current date and time. | 
| | | Resets all fields (year, month, day, hour, minute, second, fraction and timezone information) to zero-like values if they have not been parsed yet | Y-m-d|will set the year, month and day
          to the information found in the string to parse, and sets the hour,
          minute and second to 0. | 
| + | If this format specifier is present, trailing data in the string will not cause an error, but a warning instead | Use DateTime::getLastErrors() to find out whether trailing data was present. | 
Unrecognized characters in the format string will cause the parsing to fail and an error message is appended to the returned structure. You can query error messages with DateTime::getLastErrors().
      To include literal characters in format, you have
      to escape them with a backslash (\).
     
      If format does not contain the character
      ! then portions of the generated time which are not
      specified in format will be set to the current
      system time.
     
      If format contains the
      character !, then portions of the generated
      time not provided in format, as well as
      values to the left-hand side of the !, will
      be set to corresponding values from the Unix epoch.
     
The Unix epoch is 1970-01-01 00:00:00 UTC.
datetimeString representing the time.
timezoneA DateTimeZone object representing the desired time zone.
      If timezone is omitted or null and
      datetime contains no timezone,
      the current timezone will be used.
     
Note:
The
timezoneparameter and the current timezone are ignored when thedatetimeparameter either contains a UNIX timestamp (e.g.946684800) or specifies a timezone (e.g.2010-01-28T15:00:00+02:00).
   Returns a new DateTime instance or false on failure.

Example #1 DateTime::createFromFormat() example
Object-oriented style
<?php
$date = DateTime::createFromFormat('j-M-Y', '15-Feb-2009');
echo $date->format('Y-m-d');
?>
Procedural style
<?php
$date = date_create_from_format('j-M-Y', '15-Feb-2009');
echo date_format($date, 'Y-m-d');
?>
The above examples will output:
2009-02-15
Example #2 Intricacies of DateTime::createFromFormat()
<?php
echo 'Current time: ' . date('Y-m-d H:i:s') . "\n";
$format = 'Y-m-d';
$date = DateTime::createFromFormat($format, '2009-02-15');
echo "Format: $format; " . $date->format('Y-m-d H:i:s') . "\n";
$format = 'Y-m-d H:i:s';
$date = DateTime::createFromFormat($format, '2009-02-15 15:16:17');
echo "Format: $format; " . $date->format('Y-m-d H:i:s') . "\n";
$format = 'Y-m-!d H:i:s';
$date = DateTime::createFromFormat($format, '2009-02-15 15:16:17');
echo "Format: $format; " . $date->format('Y-m-d H:i:s') . "\n";
$format = '!d';
$date = DateTime::createFromFormat($format, '15');
echo "Format: $format; " . $date->format('Y-m-d H:i:s') . "\n";
?>
The above example will output something similar to:
Current time: 2010-04-23 10:29:35 Format: Y-m-d; 2009-02-15 10:29:35 Format: Y-m-d H:i:s; 2009-02-15 15:16:17 Format: Y-m-!d H:i:s; 1970-01-15 15:16:17 Format: !d; 1970-01-15 00:00:00
Example #3 Format string with literal characters
<?php
echo DateTime::createFromFormat('H\h i\m s\s','23h 15m 03s')->format('H:i:s');
?>
The above example will output something similar to:
23:15:03
