Apparently, PEAR is not correctly installed when I snag php5.1.1 and
dump it into c:\php5.1.1 and run CLI. Since I seldom use PEAR, I've
never noticed this before.

I'm fairly confident that var_dump($_ENV) did not output any key/value
that had anything useful to my needs -- I scoured that pretty
carefully, as it's where I expected my answer to be. Ditto for
$_SERVER.

Sounds like you actually know how to do this... :-)

Would such an extension be cross-platform to all PHP installs, or
Windows-only?

And is this some trivial thing that the PHP Devs just havent' had time
to do, or some monumental task of goofy OSes that nobody wants to
touch?

I'm happy to take a shot at it if it's easy, but if it's something the
PHP Devs don't want to touch, I know I ain't got a shot at it! :-)

I should have been more clear

If/when there are any $args, then $argc/$argv are set:
$ /cygdrive/c/php5.1.1/php.exe -q argv.php
array(1) {
[0]=>
string(8) "argv.php"
}

C:\Documents and Settings\rlynch>c:\php5.1.1\php.exe -q
K:\pizzahut\argv.php
array(1) {
[0]=>
string(20) "K:\pizzahut\argv.php"
}

But $argv does not contain the path of the binary PHP running -- it
has everything AFTER that in the command line.

I've not looked at the CLI SAPI at all yet, so I don't know if it gets
put anywhere, but the SAPI main() function will get what you want passed
to it. I guess now's as good a time as any...

Hey, whaddya know, it does. Check out [1]. Not sure how you'd get to
that in an extension, but it's there. Since it's not linked that's a
pretty good sign that that particular member of the struct is not used
anywhere. In fact, looking at the usage of that var [2] it may not be
available outside the SAPI code.

However, looking a bit further [3] it's defined as a static var in
php_cli.c, so you may be able to get at it with an extern declaration.
You should get the full path to the binary from the CLI module, looks
like it's NULL for any SAPI that doesn't set it. However, it was never
going to be that simple. It looks like that struct has a different name
in each SAPI, so you may need to do something to mod the code if it's
not building the CLI SAPI.

Should be able to knock something up armed with that. And yes, it should
be the same code for all platforms. I'd love to have a go at this myself
(just for fun), but unfortunately I don't have a great deal of spare
time at the moment. Let me know how you get on.

Just a thought: var_dump(ini_get('register_argc_argv')) ?
