If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Informations about the package yii2-xml-model-behavior

yii2-xml-model-behavior

Behavior and trait to serialize model as XML

Install

composer require nikserg/yii2-xml-model-behavior

Usage

Core functionality is $model->asXml(), which returns XML string, representating object. To successfully use this, the $model's class should satisfy conditions:

  1. Extends yii\base\Model
  2. Uses behavior nikserg\yii2\XmlModelBehavior\XmlModelBehavior
  3. Uses trait nikserg\yii2\XmlModelBehavior\XmlArrayableTrait
  4. Overrides fields() function to use underscore functionality (see in Explaining Example section).

Simple example better than long explaination

Result of calling $file->asXml():

Explaining example

As you can see, behavior adds only in root model. Trait should be added to root AND child models. Parameter rootElement can set the name of root XML element. In fields() function, those attributes, which names starts with underscore _, would be transformed into XML attributes of element. Other attributes would be children elements.

Behind the scene

nikserg\yii2\XmlModelBehavior\XmlModelBehavior provides $model->asXml() function. In fact, it's just a wrapper around Spatie\ArrayToXml\ArrayToXml\ArrayToXml::convert function, which is not very interesting. Interesting part starts with nesting models. To support unserscore functionality, you must override toArray() function, which is impossible in behavior. This is where trait comes in game.
