creating a model object

Yii 1.1 General Discussion

Could anybody please tell me what’s the diference between creating an object with new Model and Model::model()? For example:




$post = new Post;

$post2 = Post::model();

How are $post and $post2 any diferent?

Thanks

This




$post1 = new Post;

$post2 = new Post;

$post3 = new Post;

creates 3 different instances of an object.

This




$post1 = Post::model();

$post2 = Post::model();

$post3 = Post::model();

creates only one instance of an object to where the other variables point.

$post = new Post;

With this call you create a new instance of the Post object. So every public property/function in this class is available via $post->something.

But you couldn’t do something with e.g. ActiveRecord like find() with this class cause it is only a “normal” class.

$post = new Post::model();

With this call you create an ActiveRecord instance which is "useless" in this form until you call an AR function like find(), findAll() or findByPk().

Read the capture AR - Reading Record in the guide.

Edit: …and of course yodel’s description
