Fetch gmail contacts using google API, showing error account disabled - php

Question

I am using PHP. I want to fetch all gmail contacts of a user, i am using a PHP code that is calling google API through CURL. But, when i am doing this on localhost, it is doing well and giving me all contacts.
But when i am doing this on online server that server in US, it is giving me response "Account Disabled" and also receiving a security mail by same user from google.
i am using below code :
function getGmailContacts($user, $password) {
//========================================== step 1: login ===========================================================
$login_url = "https://www.google.com/accounts/ClientLogin";
$fields = array(
'Email' => $user,
'Passwd' => $password,
'service' => 'cp', // <== contact list service code
'source' => 'test-google-contact-grabber',
'accountType' => 'GOOGLE',
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL,$login_url);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS,$fields);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
$returns = array();
foreach (explode("\n",$result) as $line)
{
$line = trim($line);
if (!$line) continue;
list($k,$v) = explode("=",$line,2);
$returns[$k] = $v;
}
curl_close($curl);
//echo "<pre>";
//print_r($returns);exit;
if(!isset($returns['Error'])) {
//========================== step 2: grab the contact list ===========================================================
$feed_url = "http://www.google.com/m8/feeds/contacts/$user/full?alt=json&max-results=250";
$header = array(
'Authorization: GoogleLogin auth=' . $returns['Auth'],
);
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $feed_url);
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($curl);
curl_close($curl);
$data = json_decode($result, true);
//echo "<pre>";
//print_r($data);exit;
$contacts = array();
$i=0;
foreach ($data['feed']['entry'] as $entry)
{
//echo $i." ";
$entryElement = $entry;
if(isset($entryElement['gd$email'])) {
$gdEmailData = $entryElement['gd$email'][0];
//$contact->title = $entryElement['title']['$t'];
//$contact->email = $gdEmailData['address'];
$contacts[$gdEmailData['address']] = $entryElement['title']['$t'];
}
}
//var_dump($contacts);
//print_r($contacts);
return $contacts;
}
else {
if($returns['Error']=='BadAuthentication') {
//echo '<strong>User Name and Password is incorrect.</strong>';
$errorArr = array("Error"=>"User Name and Password is incorrect.");
//print_r($errorArr);
return $errorArr;
}
}
}
That mail contains that
"Someone recently tried to use an application to sign in to your
Google Account....Location: New York NY, New York, United States....."
.
I thing this error is occurring from location change.
can any one help me please? Thanks in advance.
