Ray is an expressive PHP array library for the [Codeigniter](https://codeigniter.com/) framework.
## Requirements
- PHP >= 7.1.0
- CodeIgnitor 3.x
## Installation
```bash
composer require tfhinc/ci-ray
```
Run the post install command to publish the helper and class files to the appropriate CI directories:
```bash
composer --working-dir=vendor/tfhinc/ci-ray/ run-script publish-files
```
## Loading the Library
There are a few available options for loading the Warehouse library:
### Using the `ray()` helper function
The Ray helper function will resolve the `Ray` class via the CI instance. It will either load the class or return the existing class instance:
``` php
$this->load->helper('ray');
```
### Using the Ray Class
The Ray class can be instantiated when you require it:
``` php
$ray = new TFHInc/Ray/Ray();
```
### Using the Ray CI Library
The Ray class can be loaded like any other CI library:
``` php
$this->load->library('Ray');
```
## Usage
`Ray` can be used in a variety of ways to manipulate and transfrom arrays.
### Method Usage
`Ray` enables you to interact with arrays using simple methods that return a single value or a transformed array:
```php
// Given an array...
$fruit = [
'lemon' => 'yellow',
'apple' => 'red',
'lime' => 'green',
'pear' => 'green',
];
// ...Get all of the keys except 'apple' and 'lime':
ray($fruit)->except(['apple', 'lime'])->toArray();
/*
[
'lemon' => 'yellow',
'pear' => 'green',
]
*/
// ...Get the first value:
ray($fruit)->first();
/*
'yellow'
*/
// ...Sort by value:
ray($fruit)->sortByValues()->toArray();
/*
[
'lime' => 'green',
'pear' => 'green',
'apple' => 'red',
'lemon' => 'yellow',
]
*/
```
### Method Chaining
The power of `Ray` is displayed when chaining methods together to manipulate an array:
``` php
// Given a multidimensional array...
$fruit_multi = [
[ 'id' => 1, 'name' => 'lemon', 'color' => 'yellow', 'price' => 2.25, 'qty' => 2 ],
[ 'id' => 2, 'name' => 'apple', 'color' => 'red', 'price' => 0.99, 'qty' => 12 ],
[ 'id' => 3, 'name' => 'lime', 'color' => 'green', 'price' => 3.50, 'qty' => 9 ],
[ 'id' => 4, 'name' => 'pear', 'color' => 'green', 'price' => 2.00, 'qty' => 7 ],
];
// ...Group the array by the 'color' key and only return keys 'red' or 'green':
ray($fruit_multi)->groupBy('color')->only(['red', 'green'])->toArray();
/*
[
'red' => [
[
'id' => 2,
'name' => 'apple',
'color' => 'red',
'price' => 0.99,
'qty' => 12,
],
],
'green' => [
[
'id' => 3,
'name' => 'lime',
'color' => 'green',
'price' => 3.5,
'qty' => 9,
],
[
'id' => 4,
'name' => 'pear',
'color' => 'green',
'price' => 2,
'qty' => 7,
],
],
]
*/
// ...Where the 'color' key is 'green', sum the 'price':
ray($fruit_multi)->where('color', 'green')->sum('price');
/*
5.5
*/
// ...Where the 'color' key is not 'green', filter the items that have a 'price' greater than 2:
ray($fruit_multi)->whereNot('color', 'green')->filter(function($item, $key) {
return $item['price'] > 2;
})->toArray();
/*
[
[
'id' => 1,
'name' => 'lemon',
'color' => 'yellow',
'price' => 2.25,
'qty' => 2,
]
]
*/
// ...Where the 'color' key is 'green' or 'yellow', count the number of items:
ray($fruit_multi)->whereIn('color', ['green','yellow'])->count();
/*
3
*/
// ...Retreive a column by the 'color' key and key the transformed array by the `name` key, sort by key:
ray($fruit_multi)->column('color', 'name')->sortByKeys()->toArray();
/*
[
'apple' => 'red',
'lemon' => 'yellow',
'lime' => 'green',
'pear' => 'green',
]
*/
```
### Method Return Types
`Ray` methods will return different data types depedent on the desired outcome of the method. Each documented method definition indicates the data type returned.
- The `toArray()` method should be called at the end of the method chaining sequence to return the final transformed `array`:
```php
// toArray() returns the final transformed array:
ray($fruit_multi)->column('color', 'name')->sortByKeys()->toArray();
/*
[
'apple' => 'red',
'lemon' => 'yellow',
'lime' => 'green',
'pear' => 'green',
]
*/
```
- Methods that return a `string` or an `integer` do not require the `toArray()` method. These methods should be called at the end of the method chaining sequence:
```php
// count() returns an integer:
ray($fruit_multi)->whereIn('color', ['green','yellow'])->count();
/*
3
*/
// first() returns a string:
ray($fruit)->first();
/*
'yellow'
*/
```
