Plus, depending on how you are calling the file. Meaning if the file name
that you are calling is a static file name or dynamic file name
require() and require_once() will include a file before the php parser
starts its job, but this will only happen if the name isn't dynamic.
meaning that if you have this
require("myfile.inc"); //static
and
require($var. ".inc"); //dynamic
the first one will be included into the before parsing and the second will
wait until the parser comes along and defines the $var value.
if you call require() or require_once() with a variable in the file handler
name space, it will downgrade (in a way) to just working like an include()
or include_once()
with include() or include_once() it doesn't matter if the file handle name
has a variable in it. it will always include the file after the parser
starts its job.
