本文实例为大家分享了php微信上传临时素材的具体代码，供大家参考，具体内容如下

public function uploadImg($imgUrl){

  $TOKEN=$this->getAccessToken();

  $URL ='http://file.api.weixin.qq.com/cgi-bin/media/upload?access_token='.$TOKEN.'&type=image';

  $data = array('media'=>'@'.$imgUrl);

  $result = $this->curl_post($URL,$data);

  $data = @json_decode($result,true);

  return $data['media_id'];

 }

 public function getAccessToken(){

  $url = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wxe574b1bd35d7d4da&secret=d4624c36b6795d1d99dcf0547af5443d'; 

  $result = json_decode($this->curlGet($url),true);

  return $result['access_token'];

 }

 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 (

 'type' => 'image',

 'media_id' => 'W89mt3FEaxXOMOw0fLj2Cb6A8vfMjuXrj6XW59O3l9a7Tj_h2SjlBEr4dvp4Du2R',

 'created_at' => 1464140301,
