Note Submitter: ---- little extension to handle a path like ".//aa/bb//////cc.gif" or an empty path "" for the realpath() function from lawrence@shanghaiguide.com function realPath($path) { $path = ereg_replace('/+', '/', $path); $patharray = explode('/', $path); $path = ''; $count = count($patharray); //We have multiple count($patharray) so a minor bit faster. for ($i=0; $i<$count; $i++) { if ( $patharray[$i] == '.' || $patharray[$i]== '..' || ( (($i+1) < $count) && ($patharray[$i+1]== '..')) ) { //If the current pos is a . ignore, if pos+1 == .. ignore, lastly if current = .. ignore. } else { $path .= $patharray[$i].'/'; } } //Trim trailing slash if (!empty($path)) $path = substr($path, 0, -1); return $path; } thank you, greetings bs-team
