php curl上传微信素材图片，关于php版本差异

由于我用的是php7.0.12  所以要把最重要的改成$data = array('media' => new \CURLFile($fileurl));注意PHP5.6以下才支持@,$data = array('media' => '@'.$fileurl);

$ch = curl_init();
curl_setopt($ch , CURLOPT_URL , $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,2);
curl_setopt($ch , CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch , CURLOPT_POST, 1);
$data = array('media' => new \CURLFile($fileurl));
curl_setopt($ch , CURLOPT_POSTFIELDS,$data);
$output = curl_exec($ch);
curl_close($ch);
return $output;
