Regular Expression Help

Hi ya, I'm having some trouble with regular expressions using the eregi() function. I'm a newbie, not to php, but just to regular expressions in general. What I'm trying to do is print out an option list of only 777 'moded files with .php3 extensions. The "33279" is just what 0777 in octal(?) prints out as in base 10. I didn't have the energy to convert it, and it works fine. <?php if(!isset($requested_dir)) { $requested_dir = "."; } $current_directory = opendir($requested_dir); while ($entry_name = readdir($current_directory)) { if(is_file($entry_name)) { $chmod_number = fileperms($entry_name); if($chmod_number == "33279") { if(eregi("^[[:>:]]/.php3$", $entry_name)) { print("<option>$entry_name</option>\n"); } } } } print("</select>\n"); ?> As you can see, my regular expression is screwed up. I've looked in 2 books ( Core PHP and Programming Browser Based Applications in PHP3 ) and they both really glossed over the subject of regular expressions. Basically, I just need the regular expression code that would take a string ( test.php3 ) for example, and just check for the .php3 extension.
