// PREG_FIND_RECURSIVE   - go into subdirectorys looking for more files
// PREG_FIND_DIRMATCH    - return directorys that match the pattern also
// PREG_FIND_DIRONLY     - return only directorys that match the pattern (no files)
// PREG_FIND_FULLPATH    - search for the pattern in the full path (dir+file)
// PREG_FIND_NEGATE      - return files that don't match the pattern
// PREG_FIND_RETURNASSOC - Instead of just returning a plain array of matches,
//                         return an associative array with file stats
//
// You can also request to have the results sorted based on various criteria
// By default if any sorting is done, it will be sorted in ascending order.
// You can reverse this via use of:
// PREG_FIND_SORTDESC    - Reverse order of sort
// PREG_FILE_SORTKEYS    - Sort on the keyvalues or non-assoc array results
// The following sorts *require* PREG_FIND_RETURNASSOC to be used as they are
// sorting on values stored in the constructed associative array
// PREG_FIND_SORTBASENAME - Sort the results in alphabetical order on filename
// PREG_FIND_SORTMODIFIED - Sort the results in last modified timestamp order
// PREG_FIND_SORTFILESIZE  - Sort the results based on filesize
// PREG_FILE_SORTDISKUSAGE - Sort based on the amount of disk space taken
// to use more than one simply seperate them with a | character

// Search for files matching $pattern in $start_dir.
// if args contains PREG_FIND_RECURSIVE then do a recursive search
// return value is an associative array, the key of which is the path/file
// and the value is the stat of the file.
