Solution to PHP mkdir failure under Linux

I recently made a website, and the user needed to manually create folders in the background. After the website was written, it ran very well under Windows, but something went wrong as soon as the results were uploaded to the server. After manually creating When entering the folder, no error is reported, but when I enter that directory, I cannot see the corresponding folder created. There must be a problem with the code execution. The code is as follows:

mkdir($path,0777);
if(file_exists($path))
      echo "目录创建成功！";
else
      echo "创建目录失败！";

I suspected it was a permissions issue, so I logged in to the server and authorized the directory where the folder was to be created under root: chmod 777 parpath, and then ran the code, everything was ok!

Note: parpath is the parent directory and path is the subdirectory to be created.
