PHP Standard Recommendation

from Wikipedia, the free encyclopedia

A PHP Standard Recommendation ( PSR ) is a PHP - specification , which by the PHP Framework Interop Group is published. Similar to a Java Specification Request in Java, it is used to standardize programming concepts. The aim is to enable the interoperability of components and to create a common technical basis or to implement proven concepts for a good programming style and good testability of components. Various frameworks such as B. those of the TYPO3 community, Symfony or Zend implement PSR specifications to a self-selected scope.

number Surname description status
PSR-0 Autoloading standard Naming of components in relation to manufacturer, namespace and class as well as associated directory names, so that components can be automatically reloaded if required when used in the PHP code. Adopted but obsolete as of October 21, 2014, it is recommended to use PSR-4 instead.
PSR-1 Basic coding standard General programming style, e.g. B. regulates the tags at the beginning of a PHP code, the used character set (UTF-8) and the naming of classes / methods; requires the implementation of PSR-0. Accepted
PSR-2 Coding style guide For example B. Determine where in the code line breaks are to be used in brackets, indentations and spaces or the visibility of properties and methods; requires the implementation of PSR-1. Adopted but superseded by PSR-12
