The problem with this method is assuming the ~1 part. What if I have:
'My Directory' -> MYDIRE~1
'My DirectoryForPics' -> MYDIRE~2
Now if your path has 'My DirectoryForPics' it's going to translate that into
MYDIRE~1 which won't work.

Maybe this can get you started. I don't have access to a PHP parser
right now so this is completely off the top of my head, but maybe it
will help a bit.
The function below assumes that the path contains backslashes (not
forward slashes). It also does not verify that the path is legal in
the first place (i.e. that it doesn't contain illegal characters).
Additionally, it doesn't deal with filenames, just directory names.
Maybe you can extend to handle filenames. :)
One last thing. You can't really create a function like this without
accessing the filesystem that these files are going to be stored on.
For example, let's say you have a file called "my resume.doc" The DOS
equivalent to this would be "myresu~1.doc" UNLESS there was already
another file in the same directory that had that DOS name. So, let's
say there was already another file by the name of "my results.doc" in
the directory. Then your "my resume.doc" would be called
"myresu~2.doc" The function below does not account for this.
Come to think of it, maybe this isn't all that helpful. :-P
function fullpath2dospath ($fullpath) {
if(preg_match("/^([A-Za-z]:)(.*)$/",$fullpath)) {
$driveletter = $matches[1];
$fullpath = $matches[2];
}
$dirs = explode("\",$fullpath);
foreach($dirs as $index => $dir) {
/*
Directory only needs to be modified if it
contains spaces or is longer than 8
characters
*/
if(strlen($dir) > 8 || strpos($dir," ")) {
$dir = strtr($dir," ","");
$dir = substr($dir,0,6);
$dirs[$index] = $dir."~1";
}
}
$dospath = $driveletter.implode("\",$dirs);
return $dospath;
}
