Andy -- ...and then Ns_Andy said... % % what's its use and how to use(Example)?
They're constants that identify where you are. I use __FILE__ so that I
don't have to keep tweaking my code when working in the development
environment:
# this will let us figure out where we are and then always source the right include
stuff!
# it does not work with symlinks (__FILE__ reports the *target*)
# you must have a full env tree in your devel tree; we now look exclusively in
$DEVELDIR if set
if ( ereg("/home/sites/\.php/",__FILE__) ) # are we *somewhere* in our
usual master tree?
{ $DEVELDIR = preg_replace("|/.*/home/sites/\.php(.*)/[^/]*$|","$1",__FILE__) ; }
# get the working dir
include("/home/sites/.php$DEVELDIR/includestuff.inc"); # include our various
files
Our repository is under /home/sites/.php and there are various
production, development, and test dirs under there. No more hard-coding
/home/sites/.php/test6/includestuff.inc
in the code -- and, worse, forgetting to take it out when promoting
to production! :-) [Yeah, I know that I should assign a variable
containing the "/home/sites/\.php/" string, but it's almost not worth
it in something that has to be self-contained like this and so I haven't
bothered :-]
