Ray is a simple library that provides a fluent and elegant syntax to access elements on arrays.

Some of the features of Ray include accessing first element, last element, a specific element and it works on nested arrays too.

Installation

You can install Ray via composer package manager:

composer require celyes/ray

Usage:

The code below contains a few examples on how to use this simple library.

// create a Ray object from any array...
$array = Ray::from([
    'first' => ['foo' => 'bar'],
    'second' => ['bar' => 'baz'],
    1 => [2, 3]
])

// Access elements however you like

echo $array->first()->last(); // bar.
echo $array->nth(1)->last(); // baz

echo $array->get('first')->get('foo')->key(); // foo
echo $array->get('first')->get('foo')->value(); // bar

// we called value since it's not a string + PHP does not offer a magic method similar to __toString when it comes to numeric values.
echo $array->last->nth(1)->value(); // 3

Iterating through values

You can iterate through the values of a Ray object by using the each() method. This method accepts a callable to be executed on the every element of the array. Note that this method changes the array in place.

Here's an example:

$array = Ray::from([
    'first' => ['foo' => 'bar'],
    'second' => ['bar' => 'baz'],
    1 => [2, 3]
])

$array->each(function($key, value) {
    // do some stuff with the key and value
})

The each() method returns the same object, so you can keep chaining methods like first(), last() and all.

If you don't want to change the array in place, you can use the all() method along with the good old foreach statement. Here's an example:

$array = Ray::from([
    'first' => ['foo' => 'bar'],
    'second' => ['bar' => 'baz'],
    1 => [2, 3]
])

foreach($array->all() as $key => value) {
    // do some stuff with the key and value
}

accessing keys and values

You can access keys and values of an array using the keys() and values() methods:

$array = Ray::from([
    'first' => ['foo' => 'bar'],
    'second' => ['bar' => 'baz'],
    1 => [2, 3]
])

$array->first()->keys(); // ['foo'];
$array->nth(2)->values(); // ['baz'];
$array->last()->keys(); // [0, 1];
$array->last()->values(); // [2, 3];
