CURL上传文件之ＰＨＰ版本

PHP版本不一样上传的方式也不同
1. PHP5.6以下

$fields['file'] = "@/tmp/test.log";
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);
2. PHP5.6+
$fields['file'] = new \CURLFile(realpath($tmp_name));
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
