note 36726 added to function.realpath

After having tested Jose Miguel resolvePath() and seeing that doesn't works perfect, i've rewrite my own version using regular expresions. // This funcion performs ereg_replace iteratively until no changes is made. function iterate_ereg_replace ( $pattern, $replacement, $string) { $result = $string; do { $string = $result; $result = ereg_replace ($pattern, $replacement, $string); } while ($result != $string); return $result; } // This funcion performs the translation using regular expresions. function resolvePath2 ($dest, $orig) { if ($dest == "") return $orig; if ($orig == "") return $dest; if ($dest[0] == "/") return $dest; if ($orig[0] != "/") $orig = "/".$orig; if ($orig[strlen($orig)-1] != "/") $orig = dirname($orig)."/"; $path = $orig.$dest; $path = ereg_replace ("/+", "/", $path); $path = iterate_ereg_replace ("/\./", "/", $path); $path = iterate_ereg_replace ("/[^(/|\.)]+/\.\./", "/", $path); return $path; } Mario Carbonell. http://www.mariocarbonell.com ---- Manual Page -- http://www.php.net/manual/en/function.realpath.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+36726 Delete -- http://master.php.net/manage/user-notes.php?action=delete+36726&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+36726&report=yes Search -- http://master.php.net/manage/user-notes.php
