Introduction

Manipulating table, matrix or multidimensional data in most cases can be expressed as a collection. Collections in Eden is defined loosely and as a utility class to help managing data in a controlled and chainable format. The basic setup of a collection is described in Figure 1., _(*6)

Figure 1. Setup, _(*7)

$users = array(
    array(
        'user_name' => 'Chris',
        'user_email' => 'cblanquera@openovate.com',
        'user_location' => 'Manila, Philippines'
    ),

    array(
        'user_name' => 'Dan',
        'user_email' => 'dmolina@openovate.com',
        'user_location' => 'Manila, Philippines'
    ),
);

eden('collection', $users);, _(*8)

Collections do exactly the same thing as models except it manipulates multiple models instead. Collections can be iterable and access as arrays as well. Collections only hold model objects so if you wanted to use your own extended model, you would need to call ->setModel('Your_Model'). From here we can access properties in our collection as a method, property or back as an array. Figure 2 shows the ways to access data in action., _(*9)

**Figure 2. Accessing Collection, Models and Rows **, _(*10)

//set user name for all rows
$collection->setUserName('Chris');

// set or get any abstract key for all rows
$collection->setAnyThing();

//collections are iterable
foreach($collection as $model) {        
    echo $model->getUserName().' ';
    echo $model['user_email'];
}

//access as array
echo $collection[0]['user_name'];
//set as array
$collection[0]['user_email'] = 'my@email.com'; 

Some other utility methods not covered by th above examples are date formating and copying from one column to another. Figure 3, show how we would go about doing these things., _(*11)

Figure 3. Utility methods, _(*12)

//for each row, copy the value of post_user to the user_id column
$collection->copy('post_user', 'user_id');

//remove the row with the index of 1, reindexes all the rows
$collection->cut(1);

//returns the number of rows
$collection->count();

//adds a new row
$collection->add(array('post_title' => 'Hi'));

//returns a table array (no objects)
$collection->get();
