[PHP] include_once vs require_once From: mike cullerton (php-l <email protected>)
Date: 07/31/01

hey folks,

i'm wondering about the difference between include_once and require_once.
the manual says

  The require_once() statement replaces itself with the specified file

  The include_once() statement includes and evaluates the specified file

so, what is the difference? it's almost like one is a copy/paste and the
other is some kind of read. is there any different behavior we should expect
in scripts using one method vs another.

my first guess was that require_once wouldn't evaluate the file, but i can
execute code from within a file using either method.

thanks,
mike
