note 73194 deleted from function.realpath by danbrown

Note Submitter: Patrice Vanneufville ---- the precedent function does not work all the time : servers sometimes put a slash '/' at the end of $_SERVER['DOCUMENT_ROOT'] // transforme un chemin d'image relatif en chemin html absolu function htmlpath($relative_path) { $realpath = str_replace("\\", "/", realpath($relative_path)); $root = preg_replace(',/$,', '', $_SERVER['DOCUMENT_ROOT']); if (strlen($root) && strpos($realpath, $root)===0) return substr($realpath, strlen($root)); $dir = dirname(!empty($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : (!empty($_SERVER['SCRIPT_NAME']) ? $_SERVER['SCRIPT_NAME'] : (!empty($_SERVER['PHP_SELF']) ? $_SERVER['PHP_SELF'] : str_replace('\\','/',__FILE__) ))); return canonicalize($dir.'/'.$relative_path); } // retourne un chemin canonique a partir d'un chemin contenant des ../ function canonicalize($address) { $address = str_replace("//", "/", $address); $address = explode('/', $address); $keys = array_keys($address, '..'); foreach($keys as $keypos => $key) array_splice($address, $key - ($keypos * 2 + 1), 2); $address = implode('/', $address); return preg_replace(',([^.])\./,', '\1', $address); }
