我不断对我的软件进行调整并将其上传到服务器.由于我的客户一直在使用我的在线软件,如果一个PHP文件被部分上传(假设需要3秒才能上传),当客户点击一个链接时(比如1秒标记),他们会收到一个错误,因为该文件还在上传......
Parse error: syntax error, unexpected $end in /inc/functions.php on line 475
因为我在澳大利亚,我们的互联网......好吧......"不是很快"是一种不错的方式.
上传文件时是否使用了任何技术,因此不会对使用该软件的客户造成错误？
我唯一可以做的就是上传文件说另一个目录,然后运行一个PHP脚本,复制文件超快速...但是有更好的解决方案吗？
最终代码
感谢Greg,我能够找到最好的办法.以为我会分享我的最终代码.这有点粗糙,但是诀窍......希望它有助于某人

如果您的服务器是Linux(或其他Unix变体),那么该mv命令是原子的,可以进行这种即时更新.首先将文件复制到临时名称(如file.php.new),然后登录到服务器并
mv file.php.new file.php
(这种方法即使file.php存在,也会被新的替换).
