Google Analytics API: problems extracting some data - google-analytics

Question

How do I use this API? I can extract some data, but not all of it... I'm a bit lost and I can't find any examples in the documentation. I'm using gapi.class.php.
I have code such as:
$ga = new gapi('user','pwd');
$ga->requestReportData('id',array('browser'),array('pageviews','visits', 'timeOnSite'));
var_dump($ga);
foreach($ga->getResults() as $result)
{
print_r($result);
echo '<strong>'.$result.'</strong><br />';
echo 'Pageviews: ' . $result->getPageviews() . ' ';
echo 'Visits: ' . $result->getVisits() . '<br />';
echo 'Time On site: ' . $result->getTimeOnSite() . '<br />';
}
echo '<p>Total pageviews: ' . $ga->getPageviews() . ' total visits: ' . $ga->getVisits() . '</p>';
The above is working, but then I also want to get other data such as goals... I see this: http://code.google.com/intl/es-ES/apis/analytics/docs/gdata/dimsmets/dimsmets.html
but I'm not really sure how to call each function, or property... I'm really lost, any examples would be appreciated!

GAPI uses magic get methods. You put in the dimensions and metrics that you want and get them using the magic get methods.
For example:
$ga = new gapi('user','pwd');
$ga->requestReportData('id',array('browser'),array('pageviews','visits', 'timeOnSite'));
foreach($ga->getResults() as $result)
{
print_r($result);
echo '<strong>'.$result.'</strong><br />';
echo 'Pageviews: ' . $result->getPageviews() . ' ';
echo 'Visits: ' . $result->getVisits() . '<br />';
echo 'Time On site: ' . $result->getTimeOnSite() . '<br />';
}
echo '<p>Total pageviews: ' . $ga->getPageviews() . ' total visits: ' . $ga->getVisits() . '</p>';
array('browser') is the dimension and array('pageviews','visits', 'timeOnSite') are the metrics. $result->getPageviews() is the magic get method for the pageviews metric.
So, refer to the list and put in the dimensions and metrics you want then return them using the magic get methods of getYourdimension or getYourmetric. Note that get is lowercase and the dimension or metric begins with a capital letter.
See the documentation for more information:
Access metrics and dimensions using magic get methods
With GAPI, when data is returned from Google it is automatically converted into a native PHP object, with an interface to allow the 'get' the value of any dimesion or metric.
For example, if you request the metric 'uniquePageviews' and the dimesion 'pagePath' you can do the following:
foreach($ga->getResults() as $result)
{
echo $result->getUniquePageviews();
echo $result->getPagePath();
}
