//This file has become useless for now
/*
* Find files in a directory matching a pattern
*
*
* Paul Gregg <pgregg@pgregg.com>
* 20 March 2004, Updated 20 April 2004
* Updated 18 April 2007 to add the ability to sort the result set
* Updated 9 June 2007 to prevent multiple calls to sort during recursion
* Updated 12 June 2009 to allow for sorting by extension and prevent following
* symlinks by default
* Version: 2.3
* This function is backwards capatible with any code written for a
* previous version of preg_find()
*
* Open Source Code: If you use this code on your site for public
* access (i.e. on the Internet) then you must attribute the author and
* source web site: http://www.pgregg.com/projects/php/preg_find/preg_find.phps

// 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
// PREG_FIND_FOLLOWSYMLINKS - Recursive searches (from v2.3) will no longer
// traverse symlinks to directories, unless you
// specify this flag. This is to prevent nasty
// endless loops.
//
// 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
// PREG_FIND_SORTEXTENSION - Sort based on the filename extension
// 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.
