All data containers used in Limb implement two interfaces: DataSource and Iterator.

}

Let's define a small array of data, create an ArrayDataSet using this array and iterate over it using Iterator interface.

$dataset = array (
  array ('username'=>'jdoe','email'=>'jdoe@hotmail.com'),
  array ('username'=>'rsmith','email'=>'rsmith@cure.org'),
  array ('username'=>'nclark','email'=>'nclark@yahoo.com'),
);
 
$rs = new ArrayDataSet($dataset);
 
$str = '';
for($rs->rewind(); $rs->valid(); $rs->next())
{
  $record = $rs->current();
  $str .= 'User: '. $record->get('username') . ' ';
  $str .= 'Email: '. $record->get('email') . "\n";
}

Since Iterator interface is builtin in php5 you can simplify «foreach» usage a bit:

$dataset = array (
  array ('username'=>'jdoe','email'=>'jdoe@hotmail.com'),
  array ('username'=>'rsmith','email'=>'rsmith@cure.org'),
  array ('username'=>'nclark','email'=>'nclark@yahoo.com'),
);
 
$rs = new ArrayDataSet($dataset);
 
$str = '';
foreach($rs as $record)
{
  $str .= 'User: '. $record->get('username') . ' ';
  $str .= 'Email: '. $record->get('email') . "\n";
}

The following example will display only two first records.

$dataset = array (
  array ('username'=>'jdoe','email'=>'jdoe@hotmail.com'),
  array ('username'=>'rsmith','email'=>'rsmith@cure.org'),
  array ('username'=>'nclark','email'=>'nclark@yahoo.com'),
);
 
$pager = new lmbPagerComponent();
$pager->setItemsPerPage(2);
 
$rs = new PagedArrayDataSet($dataset);
$rs->paginate($pager);
 
$str = '';
foreach($rs as $record)
{
  $str .= 'User: '. $record->get('username') . ' ';
  $str .= 'Email: '. $record->get('email') . "\n";
}
