Sebastian Bergmann's Blog:
Map and Reduce in PHP
February 20, 2008 @ 09:31:00

In this new blog entry, Sebastian Bergmann talks about two bits of functionality that PHP has that bring it a bit closer to a full functional language - array_map and array_reduce.

Just like Python, PHP is not a full-fledged functional language, but it supports some very useful functional idioms such as map and reduce. A blog posting by Scott Moonen on Functional Python prompted me to write this posting on PHP's array_map() and array_reduce() functions that apply callback functions to arrays.

He includes examples of each (in the functional context) showing how you can map callbacks to the array values, one that adds one to each number in the array and the other that combines the values and returns the sum.
