Gmail contacts API connection

I created this class that connects to Gmail contacts, and enables you to add/edit/delete the contact.

I'm curious to see what others think of my code. If you see any areas for improvement, that would be awesome!

• The contact[] is purely for testing.

• I also realize that it could be more robust, but for my needs, this is all that I need.

```
$option = $value;
}

// LOGIN TO GMAIL
public function login()
{
if(!isset($this->email)) {
die("Email is not set");
}
if(!isset($this->password)) {
die("Password is not set");
}

$this->client = Zend_Gdata_ClientLogin::getHttpClient($this->email, $this->password, 'cp');
$this->client->setHeaders('If-Match: *');

$this->gdata = new Zend_Gdata($this->client);
$this->gdata->setMajorProtocolVersion($this->protocolVersion);
}

// Get contacts feed
public function getContacts($maxResults = 10)
{
try {

$query = new Zend_Gdata_Query('http://www.google.com/m8/feeds/contacts/default/full');
$query->maxResults = $maxResults;
$query->setParam('orderby', 'lastmodified');
$query->setParam('sortorder', 'descending');

$feed = $this->gdata->getFeed($query);

return $feed;

} catch (Exception $e) {
die('ERROR:' . $e->getMessage());
}
}

// Determine the schema type from Google
// Remove everything but the actual Schema
public function determineSchemaType($value, $format = 'remove')
{
if(!isset($value)) {
die("Schema is not set.");
}

$standard = "http://schemas.google.com/g/2005#";

if($format == 'remove') {
$schema = str_replace($standard, '', $value);

} else if ($format == 'add') {
$schema = $standard . $value;
}

return $schema;
}

// Parse Contacts Feed into simpler object

A few things to point out:

$feed = $this->gdata->getFeed($query);
        return $feed;

You can just return feed directly without initialising it.

public function determineSchemaType($value, $format = 'remove')
{
    if(!isset($value)) {
        die("Schema is not set.");
    }

    $standard = "http://schemas.google.com/g/2005#";

    if($format == 'remove') {
        $schema = str_replace($standard, '', $value);

    } else if ($format == 'add') {
        $schema = $standard . $value;
    }

    return $schema;
}

• You should be keeping consistent spacing after your ifs

• If the $format is not remove or add, $schema will return undefined/null

$results[] = $obj;
        }

        return $results;

Why are there so many extraneous empty lines?

$results = $this->gdata->insertEntry($xml, 'http://www.google.com/m8/feeds/contacts/default/full');
    echo $results->id;

What's wrong with combining them?

echo $this->gdata->insertEntry($xml, 'http://www.google.com/m8/feeds/contacts/default/full')->id;
