php - curl_init 未定义？

Question

我正在将联系人从 gmail 导入到我的页面......

由于这个错误，进程不工作

'curl_init' is not defined

我得到的建议是

1. 取消注释 objective-c url.dll
2. 将以下库复制到 windows/system32 目录:ssleay32.dll 和 libeay32.dll
3. 复制php_curl.dll到windows/system32

在尝试了所有这些之后，我刷新了我的 xampp，但即使这样还是会出现错误。

这是我尝试导入 Gmail 联系人的页面:

<?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)
                            $tempArray['email_2']=$child->getAttribute('address');
                        elseif(strpos($child->getAttribute('rel'),'other')!==false)
                            $tempArray['email_3']=$child->getAttribute('address');
                    } break
                    ;
            }
        }
        if (!empty($tempArray['email_1']))$contacts[$tempArray['email_1']]=$tempArray;
        if(!empty($tempArray['email_2'])) $contacts[$tempArray['email_2']]=$tempArray;
        if(!empty($tempArray['email_3'])) $contacts[$tempArray['email_3']]=$tempArray;
    }
    foreach($contacts as $key=>$val) {

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

    ?>
<form action="<?=$PHP_SELF?>" method="POST">
    <table>
        <tr>
            <td>Email:</td><td><input type="text" name="Email" /></td>
        </tr>
        <tr>
            <td>Password:</td><td><input type="password" name="Passwd" /></td>
        </tr>
        <tr><td colspan="2" align="center">tutsmore don't save your email and password trust us.</td></tr>
        <tr><td colspan="2" align="center"><input type="submit" name="submit" value="Get Contacts" /></td></tr>
    </table>
</form>
    <?php
}
?>

此代码完全用于调试；如果需要任何优化，我会尝试优化代码。

要使用 php 安装 curl，只需键入命令

sudo apt-get install php5-curl

安装 php 之后
