Php 如何从URL文件名中删除md5

我想更改我的网站表单：www.example.c*om/pictures/az12a322a1e54a6z5e46az

致：www.example.c*om/pictures/（picturename）

例如，当我上传一张名为（rose）的图片时，我希望链接变成：

www.example.c*om/pictures/rose

当我删除（md5功能）时，链接不起作用

配置文件是

}替换此代码的解决方案

            $md5name = md5($file);

            $md5name = basename($file);

根据这一准则

            $md5name = md5($file);

            $md5name = basename($file);

您是否询问过原始作者如何调整其脚本？如果删除md5（），则可能会遇到同名的黑白文件冲突。您确定这不会成为问题吗？如果您删除md5file，您还需要删除所有使用，解决方案是按basename（$file）更改md5（$file）
