Phpinfo() and Global Vars

How could I read all (each one) the vars displayed in phpinfo() ?
I found somewhere the reference to one or another .... but can't understand the exact difference between global var series.
Most of all, where find a complete reference of each global var accessible via PHP code (and hopefully echoable ... :pleased: ) Could I even redirect the output of phpinfo(parameter), for example ?

Note: I've already checked the PHP Manual: Predefined variables page, but it isn't complete, as itself said

Note: This list is neither exhaustive nor intended to be. It is simply a guideline as to what sorts of predefined variables you can expect to have access to in your script.

Even I got almost confused by the VBulletin management of those vars. Sometimes some are accessed by getenv() function, sometimes directly via a $HTTP_var constant.
What's the difference ???

Thanks

http://www.php.net/manual/en/function.phpinfo.php

example: phpinfo(2) will show you only the credits. ;)

To capture the output of phpinfo():

Code:

        ob_start();

        phpinfo();

        $phpinfo = ob_get_contents();

        ob_end_clean();

Thanks, Nakkid. But I wouldn't only be shown that page. For instance, I would use one by one those vars...

Thanks even to FF. Is this the usual PHP redirection method into an object ?

Bye

P.S.: I updated my original request with some more info, meanwhile...

It's called Output Buffering or Controlled Output, it's used to capture the output from going to the browser so you can do stuff with it.

Most of those vars can be accessed directly by using $HTTP_XXXXX. But to access those vars in a function, you need to use getenv("HTTP_XXXXX") or $GLOBALS["HTTP_XXXXX"], or declare them as global in the function.

Yes, thanks.
But what are the differences between ( in phpinfo() ):
- Apache variables
- Http header infos
- Php vars
and how each group of them could be accessed by php ?
(I mean with a $.... or associative array...)

Thanks again
