Warning: mkdir(): File exists
提问by clien
The file transferring to my upload folder is working well but I have a warning in mkdir. It says file exist but the picture and folder generates own name. I don't know what warning is determining.
传输到我的上传文件夹的文件运行良好，但我在mkdir 中有警告。它说文件存在但图片和文件夹生成自己的名称。我不知道什么警告正在确定。

Warning is quite clear, you are creating directory which already exists. So, just change it to
警告很清楚，您正在创建已经存在的目录。所以，只需将其更改为
if (!file_exists($path)) {
mkdir($path, 0700);
}

Use PHP's is_dir($path_to_dir)for checking if a directory exists from before.
使用 PHPis_dir($path_to_dir)检查之前的目录是否存在。
