Provides basic functions to work with variables for type `iterable` (added in PHP 7.1). Primarily to transform variables of type `iteratble` into more specific types such as `array`.

If you have an iterable somewhere and you need to pass it to a function that only takes an `array`or an `Iterator`, you have a problem. You will need to add conditional logic to find out the type of the value and transform it if needed, which gets quite involved in the case of needing an `Iterator`.

This problem is quite common, as PHP's standard library, as of version 7.1, tends to either require arrays, iterators or traversables.

Example:

```
function doStuff(iterable $iterable) {
    $iterableMinusFooBar = array_diff( $iterable, [ 'foo', 'bar' ] );
}
// Output: array_diff(): Argument #1 is not an array
```

Installation
------------

[](#installation)

To add this package as a local, per-project dependency to your project, simply add a dependency on `wmde/iterable-functions` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Iterable Functions 1.x:

```
{
    "require": {
        "wmde/iterable-functions": "~1.0"
    }
}
```

Usage
-----

[](#usage)

**When you need an array**

```
function doStuff(iterable $iterable) {
    $iterableMinusFooBar = array_diff( iterable_to_array( $iterable ), [ 'foo', 'bar' ] );
}
```

**When you need an Iterator**

```
function doStuff(iterable $iterable) {
    $firstFewThings = new LimitIterator( iterable_to_iterator( $iterable ), 42 );
}
```
