关于PHP上传的问题
move_uploaded_file 函数
上传文件
现在的要求是可以上传任意个文件
但是总的文件的大小不能超过5M
该怎么做呢？？
回复讨论(解决方案)
上传文件大小的限制一般在php.ini和httpd.conf配置文件里有修改，比如php.ini里有
upload_max_filesize = 8M
post_max_size = 10M
memory_limit = 20M
这类的设置，在httpd.conf里有
LimitRequestBody 10485760
这类设置
不过你在PHP文件里可以直接判断上传文件大小，比如判断$_FILES["file"]["size"]如果大于5M就不move_uploaded_file 移动。

总的文件大小~~不是单个，好像不对吧
上传的同时记录相应的文件上传信息（按照用户，用数据库或文件 记录上传文件的总大小或用户上传每个文件的大小）
之后做相应判断不是可以？
确认 php.ini 中
session.upload_progress.enabled = on
session.upload_progress.cleanup = off
你可以在
$_SESSION["upload_progress_laruence"]["content_length"]
中得到上传文件的总大小
我想你不会排斥 php 5.4 吧？

说的有道理，但是似乎我这需求可能无解，主要是上传附件用来发送邮件的，一次这么多，
比如第一次你可以总共传19M
第二次依旧可以总共传19M
就算放在数据库也不好判断

算了，php版本自己不能改的~客户的服务器~
你应该是单个用户的上传总大小吧，在数据库中记录比较好，每个用户加个上传总大小字段，每次对比和更新。

也就是每次发送邮件的附件不能大于5M，很好判断啊，数据库记录上传总大小，不能大于5M，每次发送文件后清空为0重新计算。
楼主位内容说错了，不是5M，是一次发送邮件的附件总大小不得超过20M~

那也总不至于加法也不会做了吧？
