What is a PSR-2?
PSR-2 Coding Style Guide PSR is a standard established by PHP-FIG(PHP Framework Interop Group). PSR-0 and PSR-4 are coding standards for PHP’s autoloaders, and PSR-1 and PSR-2 are basic coding standards. Currently, PSR-2 is becoming the most common coding standard for PHP.
What is PSR coding standard?
The PHP Standard Recommendation (PSR) is a PHP specification published by the PHP Framework Interoperability Group (PHP-FIG). It serves the standardization of programming concepts in PHP. The aim is to enable interoperability of components. The PHP-FIG is formed by several PHP frameworks founders.
What PSR-1?
PHP PSR PSR-1: Basic Coding Standard PSR-1 is an accepted recommendation and outlines a basic standard recommendation for how code should be written. It outlines naming convetions for classes, methods and constants. It makes adopting PSR-0 or PSR-4 recommendations a requirement.
What should you use for indenting according to the PSR-2 coding style guide?
Code MUST use 4 spaces for indenting, not tabs. There MUST NOT be a hard limit on line length; the soft limit MUST be 120 characters; lines SHOULD be 80 characters or less.
What is PSR in it?
PSR. Preliminary Safety Report. PSR. PHP (Hypertext Preprocessor) Standard Recommendation (programming) PSR.
What is PSR level?
The PHP Standard Recommendation (PSR) is a PHP specification published by the PHP Framework Interop Group. It comprises what should be considered the standard coding elements that are required to ensure a high level of technical interoperability between shared PHP code.
What is difference between PSR-0 and PSR 4?
The summary is that PSR-0 had some backwards compatibility features for PEAR-style classnames that PSR-4 dropped, as such it only supports namespaced code. On top of that PSR-4 does not force you to have the whole namespace as a directory structure, but only the part following the anchor point.
What PSR 4?
Overview. This PSR describes a specification for autoloading classes from file paths. It is fully interoperable, and can be used in addition to any other autoloading specification, including PSR-0. This PSR also describes where to place files that will be autoloaded according to the specification.
What PSR 3?
PSR-3 Logger Interface is a standards recommendation defining a common interface for logging libraries. The laminas-log component predates it, and has minor incompatibilities, but starting with version 2.6 provides the following compatibility features: PSR logger adapter.
What does PHP stand for?
PHP: Hypertext Preprocessor
PHP (recursive acronym for PHP: Hypertext Preprocessor ) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.
Is PHP a camelCase?
PHP owns the top-level namespace but tries to find decent descriptive names and avoid any obvious clashes. Function names use underscores between words, while class names use both the camelCase and PascalCase rules. PHP will prefix any global symbols of an extension with the name of the extension.
What is PSR rate?
Price–sales ratio, P/S ratio, or PSR, is a valuation metric for stocks. It is calculated by dividing the company’s market capitalization by the revenue in the most recent year; or, equivalently, divide the per-share stock price by the per-share revenue.
What is the purpose of PSR-2 in PHP?
Like PSR-2, the intent of this specification is to reduce cognitive friction when scanning code from different authors. It does so by enumerating a shared set of rules and expectations about how to format PHP code.
Is the PSR-2 coding style guide deprecated?
Deprecated – As of 2019-08-10 PSR-2 has been marked as deprecated. PSR-12 is now recommended as an alternative. This guide extends and expands on PSR-1, the basic coding standard. The intent of this guide is to reduce cognitive friction when scanning code from different authors.
What are the key words in PHP PSR-1?
PSR-1: Basic Coding Standard. This section of the standard comprises what should be considered the standard coding elements that are required to ensure a high level of technical interoperability between shared PHP code. The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”,…
What is the resistance of the PSR-1?
The Model PSR-1 has a resistance in darkness in excess of 1 MΩ and a resistance in bright light of less than 1.5 kΩ. Models PSR-1 and PSR1-T indicate the presence or absence of light. They should not be used for footcandle control of occupied spaces. The PSR-1-T is calibrated for 4 mA in bright light (>100 footcandles) and 20 mA in darkness
