This document summarizes the current status of PHP Standard Recommendations (PSRs). It outlines PSRs that have been accepted including PSR-0, PSR-1, PSR-2, PSR-3, PSR-4, and PSR-7. It also mentions PSRs that are in draft or review stages, such as PSR-5, PSR-6, PSR-8 through PSR-12. These draft PSRs aim to standardize autoloading, logging, caching, security disclosures, container interfaces and coding styles. The review process for new PSRs is also described involving pre-draft, draft, review and acceptance stages.

5. What’s PSR
PHP Standards Recommendations
• 直訳するとPHP標準勧告
• どうにでも自由に書けちゃうテンプレートエンジ
ンに、秩序を与える。
• 当然、言語側には何の強制力も無い
• 本当に大事なことはプロダクト。その他の瑣末な
ことに気を使う時間を極力減らす為に存在。

6. PHP-FIG
• “PHP Framework In Group”
• フレームワークの相互運用性
について議論するグループ
• その為にPSRを策定・発表

7. Accepted
• PSR-0 Autoloading Standard
• PSR-1 Basic Coding Standard
• PSR-2 Coding Style Guide
• PSR-3 Logger Interface
• PSR-4 Autoloading Standard
• PSR-7 HTTP Message Interface

8. Review
• PSR-6 Caching Interface

proposed/cache.md

9. Draft
• PSR-5 PHPDoc Standard
• PSR-8 Huggable Interface
• PSR-9 Security Disclosure
• PSR-10 Security Advisories
• PSR-11 Container Interface
• PSR-12 Extended Coding Style Guide

10. Review flow

11. Stages
1. Pre-Draft 提案段階、当然まだ番号は振られない。
2. Draft PSR-XXの番号が振られる。
3. Review PHP-FIGメンバーの投票段階
4. Accepted 正式なPSRとして認められる

12. Introducing Drafts
PSR-9 Security Disclosure
“The main goal of the PSR-9 standard is to provide
structure around the documentation a project
provides to the wider community around security
vulnerabilities that have been found (and fixed) and
those that are still pending.”

13. Introducing Drafts
PSR-10 Security Advisories
“The goal of this PSR is to give researchers,
project leads, upstream project leads and end
users a defined and structured process for
disclosing security vulnerabilities.”

14. • PSR-9 セキュリティ勧告の報告基準
• PSR-10 レポートの発見を容易にするために、セキュリティの開示ワークフ
ロー
• 要約、公開された日付、より多くの情報とユニークな参照IDへのリンクが含まれ、それぞれの
脆弱性のエントリ
• CWEおよび/またはCVE情報、可能であれば（すべてではない脆弱性のCVEとして報告されま
す）
• どのバージョンの問題が影響
• 問題の現状
• 解決した場合、修復の説明
• プロジェクトのユーザーへの影響に基づいて、低/中/高深刻度
“http://blog.phpdeveloper.org/2015/05/22/php-security-psr-9psr-10/“

15. Introducing Drafts
PSR-11 Container Interface
“The goal set by ContainerInterface is to
standardize how frameworks and libraries make
use of a container to obtain objects and
parameters
(called entries in the rest of this document).”

17. The following projects already implement the container-interop version of the interface and therefore would be willing to
switch to a Container PSR as soon as it is available.
Projects implementing ContainerInterface
• Acclimate: Adapters for Aura.Di, Laravel, Nette DI, Pimple, Symfony DI, ZF2 Service manager, ZF2 Dependency injection and any
container using ArrayAccess
• Aura.DI (v3+)
• dcp-di
• Mouf
• Njasm Container
• PHP-DI
• PimpleInterop
• XStatic
Projects implementing the delegate lookup feature
• Aura.DI
• Mouf
• PHP-DI
• PimpleInterop
• Middlewares implementing ContainerInterface

18. Introducing Drafts
PSR-12 Extended Coding
Style Guide
“This guide extends and expands on PSR-2, the
coding style guide and PSR-1, the basic coding
standard.”

20. • Keywords and True/False/Null
“PHP keywords MUST be in lower case.
The PHP reserved words int, true, object, float, false, mixed, bool, null, numeric,
string and resource MUST be in lower case”
• Strict Types, Namespace, and Use Declarations
• When present, there MUST be one blank line after the declare declaration.
• When present, there MUST be one blank line after the namespace
declaration.
• When present, the namespace declaration MUST go after the declare
declaration.
• When present, all use declarations MUST go after the namespace declaration.
• There MUST be one use keyword per declaration.

21. • Using traits
• abstract, final, and static
• Method and Function Calls
• Closures
• try, catch, finally
• Anonymous Classes
