find('all', $params)

find('all') returns an array of (potentially multiple) results. It is in fact the mechanism used by all find() variants, as well as paginate. Below are a couple of simple (controller code) examples:

function some_function() {
   ...
   $allArticles = $this->Article->find('all');
   $pending = $this->Article->find('all', array('conditions' => array('Article.status' => 'pending')));
   $allAuthors = $this->Article->User->find('all');
   $allPublishedAuthors = $this->Article->User->find('all', array('conditions' => array('Article.status !=' => 'pending')));
   ...
}

1. function some_function() {
2. ...
3. $allArticles = $this->Article->find('all');
4. $pending = $this->Article->find('all', array('conditions' => array('Article.status' => 'pending')));
5. $allAuthors = $this->Article->User->find('all');
6. $allPublishedAuthors = $this->Article->User->find('all', array('conditions' => array('Article.status !=' => 'pending')));
7. ...
8. }

In the above example $allAuthors will contain every user in the users table, there will be no condition applied to the find as none were passed.

The results of a call to find('all') will be of the following form:

Array
(
    [0] => Array
        (
            [ModelName] => Array
                (
                    [id] => 83
                    [field1] => value1
                    [field2] => value2
                    [field3] => value3
                )

            [AssociatedModelName] => Array
                (
                    [id] => 1
                    [field1] => value1
                    [field2] => value2
                    [field3] => value3
                )

        )
)

There are no additional parameters used by find('all').
