在php中阻止highlight_file函数

Question

I'm having many websites installed on the same webserver. What i wanna do, is to be able to include a same file from different websites as

<?php include '/home/site/www/path/to/file.php'; ?>

and in the same time block functions like highlight_file and file so using the following code won't displays my files content

<?php echo hightlight_file('/home/site/www/path/to/file.php'); ?>

Any help will be appreciated.

If you want your PHP files to be runnable but be safe from being read, your best option is to encode them.

Take a look at IonCube PHP Encoder and SendGuard , they are both very popular options to protect source code.

Blocking PHP function can work, but you'll never be safe because you can forget functions (can you reall list them all? What if there's one you actually need?), or new functions could be added in the future and if you do not block them you'd be exposed.
