以前使用uploadify上传文件都没有错误，最近做一个程序，使用uploadify上传log日志文件，大部分都能上传成功，包括formData的参数都能成功，但是有极个别的log文件上传的时候上传不成功。
在服务器端打印 $_POST 和 $_FILES，都为空。
日志文件名称都是统一格式的，日志也都是 utf-8编码，但是有些可以成功，有些不能成功，有哪位大神碰到过，请指点一下，谢谢！
以下是uploadify的debug信息

在服务器端打印 $_POST 和 $_FILES，都为空
是空白，还是空数组？
如果是空数组，则表示上传没有实际进行进行
如果是空白，则表示上传的文件大小超过了 post_max_size 的限定
