$_FILES为空php上传不了文件
||
$_FILES一直为空数组，enctype="multipart/form-data"也有，把post改成POST就行了，大小写很关键！
标准写法
<!-- 上传文件一定要写 enctype="multipart/form-data" -->
<form enctype="multipart/form-data" action="__URL__" method="POST">
<!-- Name of input element determines name in $_FILES array -->
Send this file: <input name="userfile" type="file" />
<input type="submit" value="Send File" />
</form>
