- 11.x core/lib/Drupal/Component/Datetime/DateTimePlus.php \Drupal\Component\Datetime\DateTimePlus::createFromFormat()
Creates a date object from an input format.
Parameters
string $format: PHP date() type format for parsing the input. This is recommended to use things like negative years, which php's parser fails on, or any other specialized input with a known format. If provided the date will be created using the createFromFormat() method. @see http://php.net/manual/datetime.createfromformat.php
string $time: String representing the time.
mixed $timezone: (optional) \DateTimeZone object, time zone string or NULL. See __construct() for more details.
array $settings: (optional) A keyed array for settings, suitable for passing on to __construct(). Supports an additional key:
- validate_format: (optional) Boolean choice to validate the created date using the input format. The format used in createFromFormat() allows slightly different values than format(). Using an input format that works in both functions makes it possible to a validation step to confirm that the date created from a format string exactly matches the input. This option indicates the format can be used for validation. Defaults to TRUE.
Return value
static A new DateTimePlus object.
Throws
\InvalidArgumentException If the a date cannot be created from the given format.
\UnexpectedValueException If the created date does not match the input value.
