CakePHP2系の環境構築 #PHP

今更ですが必要になったので。

環境

$ php --version
PHP 7.2.10-0ubuntu1 (cli) (built: Sep 13 2018 13:38:55) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies

$ composer --version
Composer version 1.8.0 2018-12-03 10:31:16

なおOSはUbuntuからフォークされたPop!_OSというOSです。

$ cat /etc/os-release
NAME="Pop!_OS"
VERSION="18.10"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Pop!_OS 18.10"

UBUNTU_CODENAME=cosmic

CakePHP2.xのインストール

簡単に言えばcomposer.jsonを作成してcomposer installすればローカルにcakephpがインストールされて使えるようになります。

以下はcomposer.jsonです。

{
    "name": "otameshi",
    "repositories": [
        {
            "type": "pear",
            "url": "http://pear.cakephp.org"
        }
    ],
    "require": {
        "cakephp/cakephp": ">=2.4.9"
    },
    "config": {
        "vendor-dir": "Vendor/"
    }
}

しかしこれでcomposer installすると以下のエラーが出てしまいます。

$  composer install
Loading composer repositories with package information
Initializing PEAR repository http://pear.cakephp.org
PHP Fatal error:  Uncaught Error: Call to undefined function Composer\Repository\Pear\simplexml_load_string() in phar:///usr/local/bin/composer/src/Composer/Repository/Pear/BaseChannelReader.php:74

ググったらxml周りのライブラリが足らないらしいのでインストールします。

$ sudo apt install php7.2-xml

これを入れたらcomposer installが通りました。

./Vendor/bin/cake bakeを実行するとファイルをよしなに作成してくれます。

よくできました。

PHPUnitのインストール

./Console/cake testを実行するとPHPUnitをインストールしろって言われます。ご丁寧にバージョン指定付きで。

Error: Please install PHPUnit framework v3.7 (http://www.phpunit.de)

composer requireコマンドでインストールします。

テストの実行

phpunitをインストールしたので実際に簡単なコンポーネントとそのテストを書いてみます。

// myapp/Controller/Component/CalculateComponent.php
<?php
class CalculateComponent {

    function add ($x, $y) {
        return $x + $y;
    }
}

// myapp/Test/Case/Controller/Component/CalculateComponentTest.php
<?php
App::uses('CalculateComponent', 'Controller/Component');
class CalculateComponentTest extends CakeTestCase {

    private $CalculateComponent = null;

    public function setUp() {
        $this->CalculateComponent = new CalculateComponent;
        parent::setUp();
    }

    function testAdd() {
        $result = $this->CalculateComponent->add(1,2);
        $this->assertTrue($result == 3);
    }
}

実際にテストを動かしてみます。

サーバーの起動

cake serverでサーバーが立ち上がります。

$ sudo ./Console/cake server

まとめ

古い環境を構築するの大変。Dockerでサクッと出来るパワーが必要。
