I am developing a php site (ISP running Apache, PHP 5), and have a security related question. I call upon various "utility" php scripts from within html pages to carry out certain functions. While it is necessary for a given html page to invoke a given php script, I do not want a user to be able to execute the scripts that are being called directly, by typing in the url for the script.
For example, if my php scripts were installed in a directory called /fooscripts/ from the web root, I would like to prevent users from accessing the scripts via the browser by typing http://mysite.com/fooscripts/somescript.php
. However, if I have /foo.html from the webroot, I would like it to be able to invoke anything within /fooscripts/
I do not believe I can use .htaccess files as this would limit the scripts from being called from within my html pages. Any recommendations would be greatly appreciated.
