php5.6+上传公众号素材，由于php版本不同，导致curl也得有变化

php5.5上下的php版本的CURL有差异

php5.5版本(包含)以下:

 1 public function upload_temporary_material($type, $file)
 2     {
 3         if (PHP_OS == "Linux"){        //Linux
 4             $data = array("media"  => "@".dirname(__FILE__).'/'.$file);
 5         }else{                        //WINNT
 6             $data = array("media"  => "@".dirname(__FILE__).'\'.$file);
 7         }
 8         $url = "https://api.weixin.qq.com/cgi-bin/media/upload?access_token=".$this->access_token."&type=".$type;
 9         $res = $this->http_request($url, $data);
10         return json_decode($res, true);
11     }
12 protected function http_request($url, $data = null)
13     {
14         $curl = curl_init();
15         curl_setopt($curl, CURLOPT_URL, $url);
16         curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
17         curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
18         if (!empty($data)){
19             curl_setopt($curl, CURLOPT_POST, 1);
20             curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
21         }
22         curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
23         $output = curl_exec($curl);
24         curl_close($curl);
25         return $output;
26     }

5.5的会报一个让你用CURLFile()来代替，但是不影响使用

php5.5版本以上:

 1     public function upload_temporary_m($type, $file)
 2     {
 3         $url = "https://api.weixin.qq.com/cgi-bin/media/upload?access_token=".$this->access_token."&type=".$type;
 4         $res = $this->http_request1($url, $file);
 5         return json_decode($res, true);
 6     }
 7     
 8     protected function http_request1($url,$path){
 9         $curl = curl_init();
10  
11         curl_setopt($curl, CURLOPT_SAFE_UPLOAD, true);
12         $data = array('file' => new CURLFile(realpath($path)));//
13         curl_setopt($curl, CURLOPT_URL, $url); 
14         curl_setopt($curl, CURLOPT_POST, 1 ); 
15         curl_setopt($curl, CURLOPT_POSTFIELDS, $data); 
16         curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
17         curl_setopt($curl, CURLOPT_USERAGENT,$_SERVER['HTTP_USER_AGENT']); 
18         $result = curl_exec($curl);
19         return $result;
20     }
