アップグレードガイド

V4へのアップグレード

v4にアップグレードすることにしたのですね！ おめでとうございます!!

Phalcon v4 には、インターフェイスへの変更、厳格なタイプ、コンポーネントの削除、新しいコンポーネントの追加など、コンポーネントへの多くの変更が含まれています。 このドキュメントは、既存のPhalconアプリケーションをv4にアップグレードするのに役立ちます。 v3と同じようにコードをスムーズに実行できるように、変更を加える必要がある部分を中心に解説します。 変更は重要です。順序通りに作業すれば容易にできます。

インストール要件

PHP 7.2

Phalcon v4 は、 PHP 7.2 もしくはそれ以降のバージョンのみをサポートしています。 PHP 7.1 was released 2 years ago and its active support has lapsed, so we decided to follow actively supported PHP versions.

PSR

Phalcon には PSR 拡張機能が必要です。 拡張機能は、こちら のGitHubリポジトリからダウンロードしてコンパイルできます。 拡張機能のインストール手順は、リポジトリの README に記載されています。 拡張機能をコンパイルしてシステムで使用可能になったら、それを php.ini でロードする必要があります。 下記のように、1行を追加してください。

extension=psr.so

変更前

extension=phalcon.so

一部のディストリビューションでは、 ini ファイル名に数字のプレフィックスが追加される場合があります。 その場合は、大きい数値を指定してください(例： 50-phalcon.ini )。

インストール

最新の zephir.phar を からダウンロードする。 システムからアクセスできるフォルダに追加します。

このリポジトリのクローンを作成

git clone https://github.com/phalcon/cphalcon

Phalconのコンパイル

cd cphalcon/
git checkout tags/v4.0.0 ./
zephir fullclean
zephir build

モジュールをチェック

Usage: Cache Documentation

xcache, apc and memcache adapters have been deprecated and removed. The first two are not supported for PHP 7.2+. apc has been replaced with apcu and memcache can be replaced with the libmemcached one.

• Removed Phalcon\Annotations\Adapter\Apc
• Removed Phalcon\Annotations\Adapter\Xcache
• Removed Phalcon\Cache\Backend\Apc
• Removed Phalcon\Cache\Backend\Memcache
• Removed Phalcon\Cache\Backend\Xcache
• Removed Phalcon\Mvc\Model\Metadata\Apc
• Removed Phalcon\Mvc\Model\Metadata\Memcache
• Removed Phalcon\Mvc\Model\Metadata\Xcache

The Cache component has been rewritten to comply with PSR-16. This allows you to use the Phalcon\Cache to any application that utilizes a PSR-16 cache, not just Phalcon based ones.

In v3, the cache was split into two components, the Frontend and the Backend. This did create a bit of confusion but it was functional. In order to create a cache component you had to create the Frontend first and then inject that to the relevant Backend (which acted as an adapter also).

For v4, we rewrote the component completely. We first created a Storage class which is the basis of the Cache classes. We created Serializer classes whose sole responsibility is to serialize and unserialize the data before they are saved in the cache adapter and after they are retrieved. These classes are injected (based on the developer’s choice) to an Adapter object which connects to a backend (Memcached, Redis etc.), while abiding by a common adapter interface.

The Cache class implements PSR-16 and accepts an adapter in its constructor, which in turn is doing all the heavy lifting with connecting to the back end and manipulating data.

For a more detailed explanation on how the new Cache component works, please visit the relevant page in our documentation.

Filter

Status: changes required

Usage: Filter Documentation

サービスロケータを利用して、 Filter コンポーネントが書き換えられました。 Each sanitizer is now enclosed on its own class and lazy loaded to provide maximum performance and the lowest resource usage as possible.

概要

The Phalcon\Filter class has been rewritten to act as a service locator for different sanitizers. This object allows you to sanitize input as before using the sanitize() method.

The values sanitized are automatically cast to the relevant types. This is the default behavior for the int, bool and float filters.

When instantiating the filter object, it does not know about any sanitizers. You have two options:

Load All the Default Sanitizers

You can load all the Phalcon supplied sanitizers by utilizing the Phalcon\Filter\FilterFactory component.

<?php

use Phalcon\Filter\FilterFactory;

$factory = new FilterFactory();
$locator = $factory->newInstance();

CallingnewInstance() will return a Phalcon\Filter object with all the sanitizers registered. The sanitizers are lazy loaded so they are instantiated only when called from the locator.

Load Only Sanitizers You Want

You can instantiate the Phalcon\Filter component and either use the set() method to set all the sanitizers you need, or pass an array in the constructor with the sanitizers you want to register.

Using the FactoryDefault

If you use the Phalcon\Di\FactoryDefault container, then the Phalcon\Filter is automatically loaded in the container. You can then continue to use the service in your controllers or components as you did before. The name of the service in the Di is filter, just as before.

Also components that utilize the filter service, such as the Request object, transparently use the new filter locator. No additional changes required for those components.

Using a Custom Di

If you have set up all the services in the Phalcon\Di yourself and need the filter service, you will need to change its registration as follows:

<?php

use Phalcon\Di;
use Phalcon\Filter\FilterFactory;

$container = new Di();

$container->set(
    'filter',
    function () {
        $factory = new FilterFactory();
        return $factory->newInstance();
    }
);

NOTE: Note that even if you register the filter service manually, the name of the service must be filter so that other components can use it

定数

The constants that the v3 Phalcon\Filter have somewhat changed.

Removed

• FILTER_INT_CAST (int!)
• FILTER_FLOAT_CAST (float!)

By default the service sanitizers cast the value to the appropriate type so these are obsolete

• FILTER_APHANUM has been removed - replaced by FILTER_ALNUM

Changed

• FILTER_SPECIAL_CHARS has changed been removed - replaced by FILTER_SPECIAL
• FILTER_ALNUM - replaced FILTER_ALPHANUM
• FILTER_ALPHA - sanitize only alpha characters
• FILTER_BOOL - sanitize boolean including “yes”, “no”, etc.
• FILTER_LOWERFIRST - sanitze using lcfirst
• FILTER_REGEX - sanitize based on a pattern (preg_replace)
• FILTER_REMOVE - sanitize by removing characters (str_replace)
• FILTER_REPLACE - sanitize by replacing characters (str_replace)
• FILTER_SPECIAL - replaced FILTER_SPECIAL_CHARS
• FILTER_SPECIALFULL - sanitize special chars (filter_var)
• FILTER_UPPERFIRST - sanitize using ucfirst
• FILTER_UPPERWORDS - sanitize using ucwords

フォーム

Forms\Form

• Phalcon\Forms\Form::clear will no longer call Phalcon\Forms\Element::clear, instead it will clear/set default value itself, and Phalcon\Forms\Element::clear will now call Phalcon\Forms\Form::clear if it’s assigned to the form, otherwise it will just clear itself.
• Phalcon\Forms\Form::getValue will now also try to get the value by calling Tag::getValue or element’s getDefault method before returning null, and Phalcon\Forms\Element::getValue calls Tag::getDefault only if it’s not added to the form.

Html

Html\Breadcrumbs　パンくずリスト

• Phalcon\Html\Breadcrumbsを追加。

Html\Tag

• Phalcon\Html\Tagを追加しました。 将来のバージョンで Phalcon\Tag を置き換えます。 このコンポーネントは静的メソッド呼び出しを使用しません。

Http\RequestInterface

• isSecureRequest を削除しました isSecure
• Removed isSoapRequested in favor of isSoap

Http\Response

• Added hasHeader() method to Phalcon\Http\Response to provide the ability to check if a header exists.
• Added Phalcon\Http\Response\Cookies::getCookies
• Changed setHeaders now merges the headers with any pre-existing ones in the internal collection
• Added two new events response::beforeSendHeaders and response::afterSendHeaders

画像

• Phalcon\Image\Enum を追加しました
• Phalcon\Image\Adapter を Phalcon\Image\Adapter\AbstractAdapter にリネームしました
• Phalcon\Image\Factory を Phalcon\Image\ImageFactory にリネームしました
• Phalcon\Image を削除しました

Image\Enum (Constants)

例:

<?php

use Phalcon\Image\Enum;

// Resizing constraints
echo Enum::AUTO;    // prints 4
echo Enum::HEIGHT;  // prints  3
echo Enum::INVERSE; // prints  5
echo Enum::NONE;   // prints  1
echo Enum::PRECISE; // prints  6
echo Enum::TENSILE; // prints  7
echo Enum::WIDTH;   // prints  2

// Flipping directions
echo Enum::HORIZONTAL; // prints  11
echo Enum::VERTICAL;   // prints  12

ログ

Status: changes required

Usage: Logger Documentation

Logger コンポーネントが PSR-3 に準拠するように書き換えられました。 This allows you to use the Phalcon\Logger to any application that utilizes a PSR-3 logger, not just Phalcon based ones.

v3では、ロガーはアダプタを同じコンポーネントに組み込んでいました。 したがって、本質的には、ロガーオブジェクトを作成する際には、開発者がロガー機能を持つアダプター(ファイル、ストリームなど)を作成していました。

For v4, we rewrote the component to implement only the logging functionality and to accept one or more adapters that would be responsible for doing the work of logging. This immediately offers compatibility with PSR-3 and separates the responsibilities of the component. また、複数のアダプタへのロギングを実現できるように、複数のアダプタをロギングコンポーネントに簡単に接続する方法も提供します。 この実装を使用することで、このコンポーネントに必要なコードを削減し、古い Logger\Multiple コンポーネントを削除しました。

ロガーコンポーネントの作成

<?php

use Phalcon\Logger;
use Phalcon\Logger\Adapter\Stream;

$adapter = new Stream('/logs/application.log');
$logger  = new Logger(
    'messages',
    [
        'main' => $adapter,
    ]
);

$logger->error('Something went wrong');

DIに登録する

<?php

use Phalcon\Di;
use Phalcon\Logger;
use Phalcon\Logger\Adapter\Stream;

$container = new Di();

$container->set(
    'logger',
    function () {
        $adapter = new Stream('/logs/application.log');
        $logger  = new Logger(
            'messages',
            [
                'main' => $adapter,
            ]
        );

        return $logger;
    }
);

Multiple Loggers

Phalcon\Logger\Multiple コンポーネントが削除されました。 logger コンポーネントを使用して複数のアダプターを登録することで、同様の機能を実装できます。

<?php

use Phalcon\Logger;
use Phalcon\Logger\Adapter\Stream;

$adapter1 = new Stream('/logs/first-log.log');
$adapter2 = new Stream('/remote/second-log.log');
$adapter3 = new Stream('/manager/third-log.log');

$logger = new Logger(
    'messages',
    [
        'local'   => $adapter1,
        'remote'  => $adapter2,
        'manager' => $adapter3,
    ]
);

// Log to all adapters
$logger->error('Something went wrong');

Messages

• Phalcon\Messages\Message そして、その複数形のPhalcon\Messages\Messages コレクションは、モデルと検証のためのメッセージを処理する新しいコンポーネントです。 過去には検証用とモデル用の2つのコンポーネントがありました。 We have merged these two, so you should be getting back a MessageInterface[] back when calling save on a model or when retrieving validation messages.
  • Changed Phalcon\Mvc\Model to use the Phalcon\Messages\Message object for its messages
  • Changed Phalcon\Validation\* to use the Phalcon\Messages\Message object for its messages

トランザクション

Removed in version 4.0:

• Removed $logger->begin()
• Removed $logger->commit()

Log Level

• Removed $logger->setLogLevel()

モデル

Status: changes required

Usage: Models Documentation

• You can no longer assign data to models while saving them

Initialization

The getSource() method has been marked as final. As such you can no longer override this method in your model to set the corresponding table/source of the RDBMS. Instead, you can now use the initialize() method and setSource() to set the source of your model.

<?php

use Phalcon\Mvc\Model;

class Users
{
    public function initialize()
    {
        $this->setSource('Users');
        // ....
    }
}

Save

The save() method no longer accepts parameters to set data. You can use assign instead.

Criteria

The second parameter of Criteria::limit() (‘offset’) must now be an integer or null. Previously there was no type requirement.

$criteria->limit(10);

$criteria->limit(10, 5);

$criteria->limit(10, null);
