正确地结束编码＆for twitter post

Question

当我的更新字符串中有一个&时，我对Twitter API的自动调用会导致问题。

在我使用CURL调用Twitter API之前，如何正确编码包含&的更新字符串$update？

// Set username and password for twitter API 
     $username = '***'; 
     $password = '***'; 

     // The twitter API address 
     $url = 'http://twitter.com/statuses/update.xml'; 

     // Alternative JSON version 
     // $url = 'http://twitter.com/statuses/update.json'; 

     // Set up and execute the curl process 
     $curl_handle = curl_init(); 

     curl_setopt($curl_handle, CURLOPT_URL, "$url"); 
     curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 10); 
     curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1); 
     curl_setopt($curl_handle, CURLOPT_POST, 1); 
     curl_setopt($curl_handle, CURLOPT_POSTFIELDS, "status=$update"); 
     curl_setopt($curl_handle, CURLOPT_USERPWD, "$username:$password"); 

     $buffer = curl_exec($curl_handle); 

     curl_close($curl_handle); 

     // check for success or failure 

     if (empty($buffer)) 
     { 
      echo 'error?!'; 
     } 

Answer 1

你有两个选择，urlencode()或http_build_query()

// Using urlencode() 
$update = 'this & that'; 
echo "status=" . urlencode($update); 

// Using http_build_query() 
$postFields = array(
    'status' => $update 
); 
echo http_build_query($postFields); 

Answer 2

运行它通过urlencode()或使用http_build_query()：

curl_setopt($curl_handle, CURLOPT_POSTFIELDS, "status=" . urlencode($update)); 

// or 

curl_setopt($curl_handle, CURLOPT_POSTFIELDS, http_build_query(array("status" => $update));
