`gcr.io/paketo-buildpacks/builder:full-cf`でPHPのアプリケーションのOCIイメージを作成します。

BuilderとStackを予めpullしておいてください。

```
docker pull gcr.io/paketo-buildpacks/builder:full-cf
docker pull gcr.io/paketo-buildpacks/run:full-cnb-cf
```

次のコマンドで"Hello World"アプリケーションを作成します。

```
mkdir -p hello-php/htdocs
cd hello-php
cat <<'EOF' > htdocs/index.php
<?php
echo 'Hello World!';
EOF

cat <<'EOF' > buildpack.yml
---
php:
  webserver: nginx
EOF
```

ここではWebServerとしてNginxを使用します。その他Apache HTTPD、PHP Built-inサーバー(`php -S`)が利用可能です。

`pack build`コマンドでイメージを作成します。

```
pack build making/pack-php --no-pull --builder gcr.io/paketo-buildpacks/builder:full-cf
```

> BuilderとStackを事前にpullしていない場合は`--no-pull`を外せば、ビルド時にBuilderとStackもpullしますが、ビルドが遅くなります。

次のようなログが出力されます。

> `pack build`時に`--publish`オプションをつけると、Docker Registryでのpushを行います。事前に`docker login`が必要です。

作成したイメージを`docker run`で起動します。

```
docker run --rm -e PORT=8080 -p 8080:8080 making/pack-php
```

アプリケーションにアクセスします。

```
$ curl localhost:8080 -w '\n'
Hello World!
```

Docker Imageのサイズを確認します。

```
$ docker images | grep making/pack-php
making/pack-php                      latest              799975538f0f        40 years ago        1.3GB
```

`pack inspect-image`でイメージを解析します。

```
$ pack inspect-image making/pack-php

おわったらDocker Imageを削除します。

```
docker rmi making/pack-php
```
