[php] ottenere i contatti da gmail

Anche se ci sono centinaia di script che permettono di importare i contatti Gmail, quello che vi proponiamo oggi è davvero semplice e facile da estendere.
Nel tutorial di oggi imparerete come creare una classe PHP che recupera i contatti Gmail.

< ?php
ini_set("display_errors","2");
error_reporting(E_ERROR | E_WARNING | E_PARSE);
require_once(‘mvc/controllers/GmailController.php’);
$GmailController = new GmailController(‘email@gmail.com’,‘xxxx’);
$contacts = $GmailController->getContacts();
if($contacts){
print ‘
‘;
print_r($contacts);
print ‘

‘;
} else {
print ‘did not work’;
}
?>

< ?php
class GmailController {
private $FEED_URL = “http://www.google.com/m8/feeds/contacts/default/full”;

$this->username = $gUsername;
$this->passwd = $gPassword;

“accountType” => “HOSTED_OR_GOOGLE”,
“Email” => $this->username,
“Passwd” => $this->passwd,
“service” => “cp”,
“source” => “my_source”
);

//initialize the curl object
$curl = curl_init($this->LOGIN_URL);
//set the curl options
$this->set_curl_options($curl, CURLOPT_POST, true);
$this->set_curl_options($curl, CURLOPT_POSTFIELDS, $this->postData);

$this->set_curl_options($curl, CURLOPT_SSL_VERIFYPEER, false);
$this->set_curl_options($curl, CURLOPT_RETURNTRANSFER, 1);

//following variable contains the responses
$response = curl_exec($curl);

//check if the user has logged in sucessfully
//and save auth key if logged in
preg_match(“/Auth=([a-z0-9_\-]+)/i”, $response, $matches);
$auth = $matches[1];
if( !empty($auth)) {
$headers = array(“Authorization: GoogleLogin auth=”.$auth);

//make the request to google contacts feed with the auth key maximum contacts is 10000
$curl1 = curl_init($this->FEED_URL);

//passing the headers of auth key
$this->set_curl_options($curl1, CURLOPT_HTTPHEADER, $headers);
//return the result in a variable
$this->set_curl_options($curl1, CURLOPT_RETURNTRANSFER, 1);

$doc = new DOMDocument();

//check the entry tag
