Check if a file has been included before?

[D. Alvarado]

Hello,
I want my scripts to be warning and error free. Is it possible to
check is a file has already been included as part of a "require",
"require_on ce" or "include" call in the script? I guess I could just
include everything and turn warnings/errors off, but I'd prefer not to
do that. Much thanks -

if you use requre or include _once() then they should never be included
again.

I do not know if there is a way to check, but years ago, in C i would write
a constant in the include file and check if it was defined in the include if
not, would include itself, then define.

What about

if( !defined('INCLU DE_THEFILE'))
{
include( 'somefile.php' );
}else{
echo 'Already included'
}
....
....
// in somefile.php
defined('INCLUD E_THEFILE')

Might not be the best way...i didn't know that including a file more than
once could be a prob.

How about:
get_included_fi les () or get_required_fi les ()

They both return an array containing all included and required files.
They both do the same thing by the way (one is an alias of the other).

Yea thats it, then I started thinking, they should just use require/include
...._once(); then it hit me, instead of going through all the code, and
writing snippets to see if it was already include, just change all includes
to .._once().

OK, as I write this, I just got an idea, perhaps a small file that shows
something cool is included at several places, and they dont want to over do
it, so they need to check if it is included.

I presume it was like

#ifndef FOO_H
#define FOO_H
....
#endif

Why can't you just use include_once(.. .) and require_once(.. .) to include
all files if you know some will be included multiple times?
