我不断地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,如果当客户单击链接(例如在 1 秒标记处)时部分上传了 PHP 文件(假设上传需要 3 秒),他们会收到错误,因为文件还在上传中……

Parse error: syntax error, unexpected $end in /inc/functions.php on line 475

当我在澳大利亚时,我们的互联网......嗯......“不是很快”是一种很好的表达方式。

上传文件时是否使用了任何技术,以免客户使用该软件时出错?

我唯一能做的就是上传文件到另一个目录,然后运行一个 PHP 脚本,以超快的速度复制文件……但是有更好的解决方案吗?

最终代码

感谢下面的格雷格,我能够找出做事的最佳方式。以为我会分享我的最终代码。这有点粗糙,但可以解决问题......希望它可以帮助某人

如果您的服务器是 Linux(或其他 Unix 变体),那么该mv命令是原子的并且可以进行这种即时更新。先将文件复制到一个临时名称(如file.php.new),然后登录服务器并

mv file.php.new file.php

(即使file.php存在也有效,它将被新的取代)。
