fatal input in flex scanner

okay... I have a function that includes multiple files in a directory - it was working but I changed something and I'm now getting a "Fatal error: input in flex scanner failed" can anyone see where I messed up? cheers, jaxon ----------------------------------- function group_include($directory) { $handle=opendir("$directory"); while ($file = readdir($handle)) { //load files in $directory into array if ($file != ".." && $file != ".") { $files_to_include[count($files_to_include)] = $file; } } //clean up and sort closedir($handle); if (is_array($files_to_include)) { while (list ($key, $val) = each ($files_to_include)) { include "$directory/$val"; } } } //include common and page specific modules $common_include_dir="modules/common"; $page_include_dir="modules/page"; group_include($common_include_dir); group_include($page_include_dir);
