curl_init undefined?

I am importing the contacts from gmail to my page .....

The process does not work due to this error

'curl_init' is not defined

The suggestion i got is to

1. uncomment destination curl.dll
2. copy the following libraries to the windows/system32 dir: ssleay32.dll and libeay32.dll
3. copy php_curl.dll to windows/system32

After trying all these, I refreshed my xampp, but even then error occurs.

This is my page where I am trying to import the gmail contacts:

<?php
resource curl_init  ([  string $url = NULL  ] )

$ch = curl_init();


curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);


curl_exec($ch);


curl_close($ch);
?>

<?php
echo "hi";

if($_POST['submit'] != '') {
    echo "hi";

    $clientlogin_url = "https://www.google.com/accounts/ClientLogin";


    $clientlogin_post = array(
    "accountType" => "HOSTED_OR_GOOGLE",
    "Email" => $_POST['Email'],
    echo "Passwd" => $_POST['Passwd'],
    "service" => "cp",
    "source" => "tutsmore/1.2"
    );


    $curl = curl_init($clientlogin_url);


    curl_setopt($curl, CURLOPT_POST, true);


    curl_setopt($curl, CURLOPT_POSTFIELDS, $clientlogin_post);


    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_ANY);


    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);


    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);


    $response = curl_exec($curl);



    preg_match("/Auth=([a-z0-9_\-]+)/i", $response, $matches);
    $auth = $matches[1];


    $headers = array("Authorization: GoogleLogin auth=" . $auth);


    $curl = curl_init('http://www.google.com/m8/feeds/contacts/default/full?max-results=10000');


    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);


    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);


    $feed = curl_exec($curl);


    echo "contacts".$contacts=array();
