Get all entries from a channel
You would do that using an ElementCriteriaModel:

$criteria = craft()-&gt;elements-&gt;getCriteria(ElementType::Entry);
$criteria-&gt;section = 'mySectionHandle';
$criteria-&gt;limit = null;

$entries = $criteria-&gt;find();


You can read all about how to work with ElementCriteriaModel’s in the Working with Elements guide in the Craft docs.
