curl_init undefined？

Question

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();


    $doc=new DOMDocument();



    if (!empty($feed)) $doc->loadHTML($feed);


    $xpath=new DOMXPath($doc);


    $query="//entry";
    $data=$xpath->query($query);

    foreach ($data as $node) {


        $entry_nodes=$node->childNodes;


        $tempArray=array();


        foreach($entry_nodes as $child) {


            $domNodesName=$child->nodeName;

            switch($domNodesName) {
                case 'title' : { 
                        $tempArray['fullName']=$child->nodeValue;
                    } break
                    ;
                case 'email' : {
                        if (strpos($child->getAttribute('rel'),'home')!==false)
                            $tempArray['email_1']=$child->getAttribute('address');
                        elseif(strpos($child->getAttribute('rel'),'work')!=false)

        if(!empty($tempArray['email_3'])) $contacts[$tempArray['email_3']]=$tempArray;
    }
    foreach($contacts as $key=>$val) {

        echo $key."<br/>";
    }

Answer 1

to install curl with php, you just type the command

sudo apt-get install php5-curl

after your install php

Answer 2

Create a new php file - like temp.php - and just add:

phpinfo();

It should give you information of your entire PHP configuration. Scroll through the installed libraries and see if cURL is there. If not, hit the Manual - http://php.net/manual/en/book.curl.php - and get it setup. The instructions there are pretty good.

Answer 3

with linux: sudo apt-get install php5.6-curl (php5-curl is gone) then restart apache ( sudo service apache2 restart )

also for command line php, for composer and such, simply adding sudo apt-get install php-curl will work because I 'think' its acting on its active version

Answer 4

resource curl_init ([ string $url = NULL ] )

Does this really appear in your source code? If so, comment it out, as it's just documentation of curl_init's return type and arguments.

Now, if curl is still giving you trouble at this point, you need to check in php.ini and make sure extension=php_curl.dll does not have a ; in front of it. (I can't tell if that's what you meant by your first comment or not.) Then use XAMPP to restart Apache.

Answer 5

For xammp server, go to your php.ini file and remove the ; mark from the beginning of the below line -

;extension=php_curl.dll

restart your apache server, now its will work fine :)..

Answer 6

I use this code block to learn if a client's host/server has curl installed or not

$ci=@curl_version();
$cv=$ci["version_number"];
if($cv) echo "curl installed";
else echo "curl is not installed";
