I don't do PHP but here's the programming approach I'd start with:

1.  Replace all instances of '/./' with '/'
2.  Break the string into an array using '/' as the delimiter.
3.  Loop through the array once and append '/' to the end of every element
unless the next non-empty element is '..', in which case you clear the array
element and the next non-empty element (which should be '..').
4.  Rejoin the array into a single string ensuring that the empty string is
used as the delimiter.

Good luck,
