public function uploadImg($imgUrl){
 
  $TOKEN=$this->getAccessToken();
  $URL =&＃39;http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token=&＃39;.$TOKEN.&＃39;&type=image&＃39;;
  $data = array(&＃39;media&＃39;=>&＃39;@&＃39;.$imgUrl);
  $result = $this->curl_post($URL,$data);
  $data = @json_decode($result,true);
   
  return $data[&＃39;media_id&＃39;];
 }
 
 public function getAccessToken(){
 
  $url = &＃39;https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wxe574b1bd35d7d4da&secret=d4624c36b6795d1d99dcf0547af5443d&＃39;;
   
  $result = json_decode($this->curlGet($url),true);
 
  return $result[&＃39;access_token&＃39;];
 }
 
 function curl_post($url, $data = null)
{
 //创建一个新cURL资源
 $curl = curl_init();
 //设置URL和相应的选项
 curl_setopt($curl, CURLOPT_URL, $url);
 if (!empty($data)){
  curl_setopt($curl, CURLOPT_POST, 1);
  curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
 }
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
 //执行curl，抓取URL并把它传递给浏览器
 $output = curl_exec($curl);
 //关闭cURL资源，并且释放系统资源
 curl_close($curl);
 return $output;
}

调用uploadImg($imgurl) 传图片地址参数
返回结果

array (
 &＃39;type&＃39; => &＃39;image&＃39;,
 &＃39;media_id&＃39; => &＃39;W89mt3FEaxXOMOw0fLj2Cb6A8vfMjuXrj6XW59O3l9a7Tj_h2SjlBEr4dvp4Du2R&＃39;,
 &＃39;created_at&＃39; => 1464140301,
