How to show php-files as plain text in Apache

Look at your httpd.conf file for the AddType of .php extension, and change it fortext/plain, and php_flag engine to the offvalue just as sait by Sam Bisbee.

But prefer do these change in the httpd.conf, the .htaccess are useless if you have a dedicated server, and lowing your perfs.

But you can also just change the extensions of your PHP scripts...

THE ANSWER:

in .htaccess-file type

php_flag engine off 
#This will prevent apache from executing *.php-files

AddType text/plain php
#this wil display php-files in browser (if not, browser will want to download file!)

My Godaddy setup wont allow me to edit the httpd.conf files, and the php_flag command doesn't work due to how they've implemented php for me.

I was able to use this in my .htaccess file:

SetHandler default-handler
AddType text/plain php

I put this in the directory above where my FTP user is allowed to access, which forces all PHP files in that directory, as well as all sub-directories to show php as plain text.

This will work for other file types as well. All you need to do is add another line with whatever extension of file you want to be forced to display in plain text. AddType text/plain cgi for example
