Whats the difference between require_once and include_once?
I been running into a problem, perhaps someone can help.
I require_once in a Pear database extension. Inside that pear database
extension
is a require_once("pear.php") and a require_once("db.php")
This file, Thomas Voxs' DbPage.php file, gets require_once inside yet
another
file (my file).
The problem is, my file brings in many require_once file's, some of which
require_once(db.php) inside of it. All I get redefinition problems all over
the place.
It appears to me that require_once doesn't work as advertised? For if it
did,
there should never be redefinition problems.
Why didn't all PHP code do like we do in C/C++ with
#define BLAH
if !defined(BLAH)
{
your code here.
}
I realize the #define trick works as I used it in my own PHP code... but
when
the basic PHP core files don't have this in them, it sort of makes
require_once
and include_once hacks! (that don't work)
Any ideas suggestions?
