How can FTP users access folders created by PHP with different user permissions?

FTP users can access folders created by PHP with different user permissions by setting the correct permissions on the folders using the chmod() function in PHP. By setting the appropriate permissions, FTP users can be granted access to the folders based on their user permissions.

// Create a new directory with specific permissions
$dir = 'new_folder';
mkdir($dir, 0777); // 0777 grants full permissions to all users

// Set permissions for the directory
chmod($dir, 0755); // 0755 grants read and execute permissions to all users and write permissions to the owner
