Currently I'm naming all my include files with the .php extension, but I heard this was bad practice as they will be parsed as individual scripts when they're not meant to be.
.inc files should be used, and I heard the safest way to use them would be to put them in a directory outside htdocs and change the include path in the php.ini file. However, I don't have access to that.
Is there any other way I can change the default include path?
