[](#type-strict-iterable-lists-with-functional-functionality-provided-to-them) There are 2 primary ideas behind this library. 1. To provide a way of specifying a type to elements of an array within PHP and forcing adherence to this. 2. To provide a series of functional implementations to an iterable type within PHP. With HasPHP, these have been combined. #### Installation [](#installation) With composer installed, in your project type: `composer require xcgpseud/hasphp` --- #### Usage [](#usage) HasPhp will ensure that any items in the initial array are the same type as the one specified. When using Objects - it will ensure that they are all the same type as the first in the array. Here are a few usage examples: > To get all odd numbers between 0 and 200, multiply them by 2 and retrieve the sum of said numbers ``` \HasPhp\Types\Ints::with(range(0, 200)) ->filter(fn (int $i): bool => $i % 2 != 0) ->map(fn (int $i): int => $i * 2) ->sum(); ``` > To get all people above the age of 18 ``` \HasPhp\Types\Objects::with($peopleArray) ->filter(fn (Person $x): bool => $x->getAge() > 18); ``` Functions such as `map` and `filter` return an IterList so you can chain more functions on to the end. In order to retrieve the array, use `->get()` **All functions** Signature is in order of the array within the List -> params -> returns as opposed to Haskell's. i.e. Haskell's filter is `(a -> bool) -> [a] -> [a]` because it's called like so: `filter (even) [5, 1, 2, 7]`whereas Hasphp's is `[a] -> (a -> bool) -> [a]` because we define the list prior to the function.
