如何将curl_init设置为变量？

Question

我想创建这样一条线，在PHP中：

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

我这样做，所以我可以为$卷曲设置选项...

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 

为什么不能我设置了$ cURL（它给了我一个错误），有没有办法绕过它？

curl_init之前，不要使用$：

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