- 3.2 Migration Guide
- Minimum PHP 5.5 Required
- New Enhancements
- Migration Steps
CakePHP 3.2 is an API compatible upgrade from 3.1. This page outlines the changes and improvements made in 3.2.
CakePHP 3.2 requires at least PHP 5.5.9. By adopting PHP 5.5 we can provide better Date and Time libraries and remove dependencies on password compatibility libraries.
As we continue to improve CakePHP, certain features are deprecated as they are replaced with better solutions. Deprecated features will not be removed until 4.0:
Shell::error() is deprecated because its name does not clearly indicate
that it both outputs a message and stops execution. Use
Cake\Database\Expression\QueryExpression::type() is deprecated. Use
Cake\Database\Type\DateTimeType::$dateTimeClass is deprecated. Use
DateTimeType::useMutable() or DateTimeType::useImmutable() instead.
Cake\Database\Type\DateType::$dateTimeClass is deprecated. Use
Cake\ORM\ResultSet::_calculateTypeMap() is now unused and deprecated.
Cake\ORM\ResultSet::_castValues() is now unused and deprecated.
action key for
FormHelper::create() has been deprecated. You
should use the
url key directly.
Upon upgrading you may encounter several deprecation warnings. These warnings are emitted by methods, options and functionality that will be removed in CakePHP 4.x, but will continue to exist throughout the lifetime of 3.x. While we recommend addressing deprecation issues as they are encountered, that is not always possible. If you’d like to defer fixing deprecation notices, you can disable them in your config/app.php:
'Error' => [ 'errorLevel' => E_ALL & ~E_DEPRECATED & ~E_USER_DEPRECATED, ]
The above error level will suppress deprecation warnings from CakePHP.
The Carbon library has been replaced with cakephp/chronos. This new library is a fork of Carbon with no additional dependencies. It also offer a calendar date object, and immutable versions of both date and datetime objects.
Date class allows you to cleanly map
DATE columns into PHP objects.
Date instances will always fix their time to
00:00:00 UTC. By default the
ORM creates instances of
Date when mapping
DATE columns now.
FrozenDate classes were added. These classes offer
the same API as the
Time object has. The frozen classes provide immutable
Date. By using immutable objects, you can prevent
accidental mutations. Instead of in-place modifications, modifier methods return
use Cake\I18n\FrozenTime; $time = new FrozenTime('2016-01-01 12:23:32'); $newTime = $time->modify('+1 day');
In the above code
$newTime are different objects. The
$time object retains its original value, while
$newTime has the modified
value. See the Immutable Dates and Times section for more information. As of 3.2,
the ORM can map date/datetime columns into immutable objects. See the
Enabling Immutable DateTime Objects section for more information.
In order to make setting headers related to Cross Origin Requests (CORS) easier,
CorsBuilder has been added. This class lets you define CORS related
headers with a fluent interface. See Setting Cross Origin Request Headers (CORS) for more information.
Router::redirect() now raises
when a redirect condition is reached. This exception is caught by the routing
filter and converted into a response. This replaces calls to
response->send() and allows dispatcher filters to interact with redirect
Containing the same association multiple times now works as expected, and the query builder functions are now stacked.
Function expressions now correctly cast their results. This means that
$query->func()->current_date() will return datetime
Field data that fails validation can now be accessed in entities via the
Entity accessor method lookups are now cached and perform better.
The Validator object has a number of new methods that make building validators less verbose. For example adding validation rules to a username field can now look like:
$validator->email('username') ->ascii('username') ->lengthBetween('username', [4, 8]);
Shell::success() were added.
These helper methods make using commonly used styling simpler.
Cake\Console\Exception\StopException was added.
Shell::abort() was added to replace
Shell::error() no longer call
Cake\Console\Exception\StopException. If your shells/tasks are
\Exception where these methods would have been called, those catch
blocks will need to be updated so they don’t catch the
StopException. By not
exit() testing shells should be easier and require fewer mocks.
Helpers can now implement an
initialize(array $config) hook method like
other class types.
A new configuration option
Error.extraFatalErrorMemory can be set to the
number of megabytes to increase the memory limit by when a fatal error is
encountered. This allows breathing room to complete logging or error handling.
