RE: [PHP] Require_once problem
Well, the way I've read it is that if you use require within control
structures then all files are included, regardless of whether the script
exits before it reaches its next if...elseif...else or case statement. With
include that does not happen. So the general rule of thumb would be to use
require() if you are not using it within these control structures, and use
include() if you actually do need to use include statements in your control
structures. Now, that said, I'm really not sure if that is true for the
require_once and include_once functions also. You might want to look into
that. Hope this helps a little.

Subject: [PHP] Require_once problem
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?

That's how it *used* to work (somewhere back around 4.0.3, if memory serves). Now, the only difference is that the require versions will produce a fatal error if the file is not present, whereas the include versions will only generate a warning. Cheers!
