Can a client view server-side PHP source code?

Question

I\'m developing a PHP application that has to respond to request from several clients, and I thinks \"Can any of the clients see the PHP code that I\'m writing?\".

Answer 1

No. Assuming you've installed a L/UAMP server properly, or aren't printing out (echo, print_r, etc.) and of the guts of your code, the PHP will be processed and the logic or HTML it's meant to output will be used on the page, not visible.

N.B. If there isn't an 'index' in a directory or a proper .htacess file, an Apache server will show a list of files in the directory, which can be downloaded and reviewed.
