curl发送文件

通过PHP的CURL,可以的发送文件:
// URL on which we have to post data
$url = "http://localhost/tutorials/post_action.php";
// Any other field you might want to catch
$post_data['name'] = "khan";
// File you want to upload/post
$post_data['file'] = "@c:/logs.log";

// Initialize cURL
$ch = curl_init();
// Set URL on which you want to post the Form and/or data
curl_setopt($ch, CURLOPT_URL, $url);
// Data+Files to be posted
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
// Pass TRUE or 1 if you want to wait for and catch the response against the request made
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// For Debug mode; shows up any error encountered during the operation
curl_setopt($ch, CURLOPT_VERBOSE, 1);
// Execute the request
$response = curl_exec($ch);

// Just for debug: to see response
echo $response;

发送多个文件也一样:
$post_data['alian_error_log'] = "@c:/alian_app_error.log";
$post_data['myapp_error_log'] = "@c:/myapp_error.log";
