Segments
View the API Documentation for this class
At the moment, the Segment class is pretty dumb, but it is slightly easier than plain arrays.
You can get the name of the segment:
$name = $segment->getName();
And then you can access the content of the segment like so:
# Access simple string data
$segment->getElement(0);
# Or nested array content
$segment->getElement(1)[1];
If you just want all of the segments data you can retrieve it like so:
foreach ($segment->getAllElements() as $element) {
}
