Functional PHP: Functional primitives for PHP
NOTE: functional-php used to come with a C extension that implemented most of the functions natively. As the performance differences weren’t that huge compared to the maintenance cost it has been removed.
A set of functional primitives for PHP, heavily inspired by Scala’s traversable collection, Dojo’s array functions and Underscore.js
- Works with arrays and everything implementing interface
Traversable
- Consistent interface: for functions taking collections and callbacks, first parameter is always the collection, then the callback.
Callbacks are always passed
$value
,$index
,$collection
. Strict comparison is the default but can be changed - Calls 5.3 closures as well as usual callbacks
- All functions reside in namespace
Functional
to not raise conflicts with any other extension or library
