# Accumulate
|
||
|
|
|
||
|
|
Welcome to Accumulate on Exercism's PHP Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Implement the `accumulate` operation, which, given a collection and an
|
||
|
|
operation to perform on each element of the collection, returns a new
|
||
|
|
collection containing the result of applying that operation to each element of
|
||
|
|
the input collection.
|
||
|
|
|
||
|
|
Given the collection of numbers:
|
||
|
|
|
||
|
|
- 1, 2, 3, 4, 5
|
||
|
|
|
||
|
|
And the operation:
|
||
|
|
|
||
|
|
- square a number (`x => x * x`)
|
||
|
|
|
||
|
|
Your code should be able to produce the collection of squares:
|
||
|
|
|
||
|
|
- 1, 4, 9, 16, 25
|
||
|
|
|
||
|
|
Check out the test suite to see the expected function signature.
|
||
|
|
|
||
|
|
## Restrictions
|
||
|
|
|
||
|
|
Keep your hands off that collect/map/fmap/whatchamacallit functionality
|
||
|
|
provided by your standard library!
|
||
|
|
Solve this one yourself using other basic tools instead.
