When my app starts up, it discovers where it has been installed using:

$instdir = dirname (__FILE__);

Now, I have no control over where this might be in the file system, and
the user may well put it somewhere such that the path contains spaces.
I'm passing this round the app, and in the fullness of time may be doing
things like:

$fp = fopen ($instdir . "/wiggy", "r");

Does it matter to PHP filesystem functions if the filename contains
spaces?

But what's worse, I'll also be passing $instdir to shell scripts via
exec ().

Seems to me I can:

1) search/replace $instdir to escape spaces with backslash-space. But
does this mess up PHP filesystem functions?

2) leave $instdir as-is, but use escapeshellarg on it whenever I need to
pass it through exec().

Which is the better approach?
