README
PHP Library that provides generic and scalable Data Models (abstract model class) for any type of data handling.
This perfect and suitable for when developing MVC frameworks, Api clients, wrappets and/or any type of project that requires data handling.
Models inspired by Laravel and our very own Wordpress MVC.
Requires
- PHP >= 5.4
Usage
When defining your models, extend them from the Model
abstract class.
In the following example, a Product
data model will be created and will extend from the Model
abstract class.
use TenQuality\Data\Model; class Product extends Model { }
Then instantiate your models like this:
$product = new Product;
Adding data
Very easy, simply add the data like an object property.
// Set data $product->price = 19.99; $product->name = 'My product'; $product->brandName = '10 Quality'; // Get data echo $product->price; // Will echo 19.99 echo $product->name; // Will echo My product echo $product->brandName; // Will echo 10 Quality
Creating aliases
Aliases are model properties that are set or get by class methods. This are defined in the model.
In the following example, an alias will be created in the model to display prices with currenty.
use TenQuality\Data\Model; class Product extends Model { /** * Method for alias property `displayPrice`. * Return `price` property concatenated with the $ (dollar) symbol */ protected function getDisplayPriceAlias() { return '$'.$this->price; } /** * Method for alias property `displayPrice`. * Sets a the price value if the alias is used. */ protected function setDisplayPriceAlias($value) { $this->price = floatval(str_replace('$', '', $value)); } }
Then use it like this:
$product->price = 19.99; // Get alias property echo $product->displayPrice; // Will echo $19.99 // Set alias property $product->displayPrice = 29.99; // Echo property echo $product->price; // Will echo 29.99 echo $product->displayPrice; // Will echo $29.99
You can also init the models with the construct method (passing properties as an array):
$product = new Product(['price' => 19.99]); // Echo property echo $product->price; // Will echo 19.99
Casting
Before using any casting options, the model needs to define which properties are visible and which are hidden. This is done by listing the visible ones like this:
use TenQuality\Data\Model; class Product extends Model { protected $properties = [ 'name', 'price', 'displayPrice', ]; }
Notice that both properties and aliases can be listed. Following the samples above, property brandName
will stay hidden from casting.
Cast the model like this:
var_dump($model->toArray()); // To array var_dump($model->__toArray()); // To array echo (string)$model; // To json encoded string echo $model->toJSON(); // To json encoded string echo $model->__toJSON(); // To json encoded string // You can force JSON casting to be encoded using different options and depth, as described in PHPs documentation // http://php.net/manual/en/function.json-encode.php echo $model->toJSON(JSON_NUMERIC_CHECK, 600);
Collections
This package also provides a Collection
class that will facilitate the use of multiple models or data records.
Collections behave like normal arrays would:
use TenQuality\Data\Collection; $collection = new Collection; // Add your models as you would normally do with arrays $collection[] = $product; $collection[] = $product; echo count($collection); // Thrown count var_dump($collection[0]); // Dumps first model added // Loop a collection foreach ($collection as $product) { // Do your stuff }
Collections can be sorted very easily:
use TenQuality\Data\Collection; $collection = new Collection; // Add your models as you would normally do with arrays $collection[] = new Product(['price' => 99.99]); $collection[] = new Product(['price' => 2.99]); // Loop a collection foreach ($collection->sortBy('price') as $product) { echo $product->price; // 2.99 will display first and then 99.99 } // Change sorting criteria // http://php.net/manual/en/array.constants.php print_r($collection->sortBy('price', SORT_NUMERIC));
Data in a collection can be grouped very easily:
use TenQuality\Data\Collection; $collection = new Collection; // Add your models as you would normally do with arrays $collection[] = new Fruit(['name' => 'Apple', 'color' => 'red']); $collection[] = new Fruit(['name' => 'Banana', 'color' => 'yellow']); $collection[] = new Fruit(['name' => 'Strawberry', 'color' => 'red']); $collection[] = new Fruit(['name' => 'Orange', 'color' => 'orange']); // Loop a collection foreach ($collection->groupBy('color') as $color => $fruits) { // This will group the data in sub arrays based on colors echo $color; foreach ($fruits as $fruit) { echo $fruit; // Fruit in the color grouped by. } }
Cast the colleciton like this:
var_dump($collection->toArray()); // To array var_dump($collection->__toArray()); // To array echo (string)$collection; // To json encoded string echo $collection->toJSON(); // To json encoded string echo $collection->__toJSON(); // To json encoded string // You can force JSON casting to be encoded using different options and depth, as described in PHPs documentation // http://php.net/manual/en/function.json-encode.php echo $collection->toJSON(JSON_NUMERIC_CHECK, 600);
