Re: Hidden include_path Fall Back?

The default of php.ini starts with '.' in the first place, I think, so unless you go out of your way to change it, you'll get '.' from a fresh install anyway. I personally would not rely on the behaviour of the code unless you can find Documentation on http://php.net that says it will work this way. It cannot be that hard to append/prepend '.:' yourself to the include_path... On Wed, August 8, 2007 4:05 am, imacat wrote: > Dear all, > > Hi. I'm new to this list.
