    [uri] => /dir/index.php
    [filename] => /home/htdocs/dir/index.php
    [args] => var=value

Apparently on PHP 4.2, this function returns an array instead of an object.

That being the case, the example code above would translate to:

<?php
$info = apache_lookup_uri('index.php?var=value');
print_r($info);

if (file_exists($info['filename'])) {
   echo 'file exists!';
}
?>

A means of making this transparent so that the object syntax works, is left as an exercise for the reader. ;-)

A useful feature is that if you have content negotiation on (Options MultiViews) Apache will resolve the negotiation for you if possible.  Thus www.example.com/blah will resolve to /base/blah.php or /base/blah.html or even /base/blah.en.html as appropriate.
