----
for some reason or another, i couldn't get realpath to work. so i made my own. it's very
simple, but it does work. it checks vs. the current directory (the one from which the script is
being run).

function myRealPath($path) {
// Check if path begins with "/".
if(strpos($path,"/")==0) {
$path = $_SERVER['DOCUMENT_ROOT'].$path;
} else {
// Strip slashes and convert to arrays.
$currentDir = preg_split("/\//",dirname($_SERVER['PATH_TRANSLATED']));
$newDir = preg_split('/\//',$path);
// Drop one directory from the array for each ".."; add one otherwise.
foreach($newDir as $dir) {
if($dir == "..")
array_pop($currentDir);
else
array_push($currentDir,$dir);
}
// Return the slashes.
$path = implode($currentDir,"/");
}
return $path;
}
