Skipping items in a loop

Hello again; I have a directory that I am opening and reading to produce an array of contents; files and subdirectories. There are a number of subdirectories that I do not want to open and read the contents of, and others that I do want to open and read the contents of. This code is supposed to produce two arrays. One with directories and the other with files, including the path. This is so I can create the directories and copy the files. Certain files are specific to the source directory structure and I do not want them copied. The only way I can think of is to loop though the $dir_only array to see if it matches an item in the $dirs array so I can have the code by pass it. But that is in the middle of a while loop that is already in the middle of a loop. I have not been able to get it to work as I want. using php 5.1.2 Does anyone have a better suggestion (that will work in the context of this code, I do not want to do major rewriting if I can avoid it). Thanks in advance Jeff k The code follows:

                           $cont = array();
                           $dir_only = array();
                           $dir_only[0] = 'jk/collections';
                           $dir_only[1] = 'jk/extras';
                           $dir_only[2] = 'jk/group_info';
                           $dir_only[3] = 'jk/group_routes';
                           $dir_only[4] = 'jk/groups_in';
                           $dir_only[5] = 'jk/in';
                           $dir_only[6] = 'jk/log';
                           $dir_only[7] = 'jk/out';
                           $dir_only[8] = 'jk/requests';
                           $dir_only[9] = 'jk/store';
                          $dirs = array();
                          $dirs_a = array();
                          $files = array();
                          $cltag = '?'.'>'; // <- for php closing tag. If I do it literally, it screws up the syntax coloring in my code editor.
                          $rd = opendir('jk') or die("Could not open jk as source dir");
                          while($x = readdir($rd))
