新人求助，关于android上传图片，php作为服务器端接收图片问题

问题描述：android端向php端发送发送图片，php接收图片，将图片路径写入数据库，测试的两台服务器，其中一台正常，另外一台无法接收图片，现在不知道是不是服务器的问题，请各位大神帮忙看看，不胜感谢！！！
php端：

$sub_path = './' . time() . basename($_FILES['uploadedfile']['name']);
	if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $sub_path)) {
		echo json_encode('success');
	} else {
		echo json_encode('fail');
	}

android端：

将$_FILES打印到一个txt文件里面看一下有没有数据就知道了(file_put_contents，var_export)
一台服务器可以，一台不行，就有可能是路径的问题了，移动失败
