Funcy is a project mainly written in PHP, based on the MIT license.
A set of functionally useful functions for functional functional programming in PHP.
I (the developer) am a big fan of functional programming. It has had a big — positive — impact on all I do. I also am a big fan of scripting languages such as Ruby, Python and PHP. PHP has closures (anonymous functions) as of 5.3, but no equivalents for powerful functions from functional languages such as currying, function composition etc.
Funcy brings all the functioning functional funkyness to PHP. Awesome!
partially applying functions
add(a, b): a + b
add_five: add(5)
print add_five(10) // 15composing functions
add(a, b): a + b
square(x): x * x
squad(a, b): compose(square, add)
print squad(2, 3) // ((2 + 3) * (2 + 3)) = 25!map, reduce (fold)
There are array_map and array_reduce in PHP already, but they only work for arrays. I want something that works for all traversable things, be they arrays or objects.
