我如何检查文件是否完全上传... ??? [英] how can i check if a file is completely uploaded...???
问题描述
亲爱的，
我为客户创建了一个应用程序，客户可以将
..csv文件上传到指定的ftp -目录。在服务器上，一个由cronjob触发的php脚本，
读取所有数据，将其导入mySQL数据库
并删除.csv文件后导入。
到目前为止，非常好。
但在某些情况下，当文件不完整时，cronjobs开始运行
已上传。所以数据的一部分被截断了。 :-(
是否有任何方法在PHP中检查文件是否完全通过ftp上传
或不？我没有找到任何关于这在php.net上会很棒，如果
有人可以帮我解决这个问题。
提前多多感谢，
dino
dear all,
i''ve created an application for a customer where the customer can upload
..csv-files into a specified ftp-directory. on the server, a php-script,
triggered by a cronjob, reads all the data, imports it into a mySQL database
and deletes the .csv-file after the import.
so far, so good.
but in some cases the cronjobs starts running when the file is not completely
uploaded. so a part of the data is truncated. :-(
is there any method in php to check if a file is completely uploaded via ftp
or not? i didn''t find anything about this on php.net and it would be great if
someone could help me with this problem.
thanks a lot in advance,
dino
推荐答案
嗯也许你可以查看文件大小？使用php函数....
我也有过与你相同的经历......我所做的是手动完成
cronjonb两次..所以它会确保文件完成ftp
首先..
可能是我们需要更多经验的php用户来帮助解决这个问题..

你好，
感谢你的投入，问题是，那个文件大小改变
关于.csv文件中行数的不同。
i想到了2种可能的解决方案，但它们有点便宜 br />
变通办法而不是一个干净的解决方案：
第一个想法：我要求客户在.csv的底部添加额外的一行
，例如" ### endoffile ###" ;.在php cronjob开始之前
工作它检查.csv是否存在此
end-of-document-flag。
第二个想法：我要求客户上传另一个带有
特殊文件名的小文件，例如" startjob.txt" _AFTER_上传主
文件。如果php conjob没有找到这个文件，它会立即退出。
（导入后的课程 - 两者都会自动删除）
虽然这可能有用，我不认为这是
所有的完美解决方案。也许有人在这里有一个原生的方法检查文件是否已完成上传。
最好的问候，

hello,
thanks for your input, the problem is, that the filesizes changes
depandant on the number of line in the .csv file.
i thought about 2 possible solutions, but they are kind of "cheap
workarounds" instead of a clean solutions:
1st idea: i ask the customer to add an additional line at the bottom
of the .csv, e.g. "###endoffile###". before the php cronjob starts
working it checks the .csv for the existance of this
"end-of-document-flag".
2nd idea: i ask the customer to upload another small files whith a
special filename e.g. "startjob.txt" _AFTER_ the uploading of the main
file. if the php conjob does not find this file, it exits immediately.
(after the import -of course- both will will be deleted automatically)
although this may work, i don''t think it''s the perfect solution at
all. maybe someone here has a "native" method to check if a file is
completey uploaded.
best regards,
dino
