What are best practices for setting folder permissions when uploading files with PHP?

When uploading files with PHP, it is important to set appropriate folder permissions to ensure the security of your application. A common best practice is to set the folder permissions to allow the web server user (such as Apache or Nginx) to write to the folder, while restricting access to other users. This can be achieved by setting the folder permissions to 755, which gives the owner full access, and read and execute permissions to others. 

// Set folder permissions to allow the web server user to write to the folder
$folder = '/path/to/upload/folder';
chmod($folder, 0755);
