如何將curl_init設置爲變量？

Question

我想創建這樣一條線，在PHP中：

$cURL = $curl_init('http://mysite.com/2'); 

我這樣做，所以我可以爲$捲曲設置選項...

curl_setopt($cURL, CURLOPT_PROXY, $proxy); // proxy 
curl_setopt($cURL, CURLOPT_PROXYPORT, $port); // proxy port 
curl_setopt($cURL, CURLOPT_HTTPAUTH, CURLAUTH_ANY); // use authentication 
curl_setopt($cURL, CURLOPT_HTTPHEADER, $headers); // send the headers 
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, 1); // We need to fetch something from a string, so no direct output! 
curl_setopt($cURL, CURLOPT_FOLLOWLOCATION, 1); // we get redirected, so follow 
curl_setopt($cURL, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($cURL, CURLOPT_SSL_VERIFYHOST, 1); 
curl_setopt($cURL, CURLOPT_UNRESTRICTED_AUTH, 1); // always stay authorised 
$wrong = curl_exec($cURL); // Get it 
curl_close($cURL); // Close the curl stream 

爲什麼不能我設置了$ cURL（它給了我一個錯誤），有沒有辦法繞過它？

curl_init之前，不要使用$：

$cURL = curl_init('http://mysite.com/2');
