How can one selectively hide or protect only .class files in a directory while still allowing access from PHP scripts?

To selectively hide or protect only .class files in a directory while still allowing access from PHP scripts, you can use the following method: You can create a .htaccess file in the directory where your .class files are located and add the following code to deny access to any files with the .class extension. This will prevent direct access to the .class files while still allowing PHP scripts to access them.

<FilesMatch "\.class$">
    Order allow,deny
    Deny from all
</FilesMatch>
