note 29484 added to function.dirname

Here's a lil' code I cooked up to figure out the base directories, as far as filesystem vs. URLs. This is very helpful for, say an image that you want to use getimagesize(); on, but only have the URL oriented directory. You can then use str_replace(); or preg_replace(); and swap the values out easily! Note that in order for it to work, you must include the pointer ($big = &$y), rather than simply copying ($big = $y). // separate each dir into array elements $x = explode('/', dirname($_SERVER['SCRIPT_FILENAME'])); $y = explode('/', dirname($_SERVER['SCRIPT_NAME'])); $countX = count($x); $countY = count($y); $max = max($countX, $countY); $min = min($countX, $countY); $dif = $max-$min; if (isset($x[$max-1])) { // $x is the biggest $big = &$x; // make $big a pointer to $x $lil = &$y; // make $lil a pointer to $y } else { // $y is the biggest $big = &$y; // make $big a pointer to $y $lil = &$x; // make $lil a pointer to $x } for($i=$max-1;$i>=$dif; $i--) { if ($big[$i]==$lil[$i-$dif]) { // path matches unset($big[$i], $lil[$i-$dif]); // erase any common elements } } // all that's left is uncommon elements, join array(s) $root_dir = join('/', $x).'/'; $root_url = join('/', $y).'/'; -- http://www.php.net/manual/en/function.dirname.php http://master.php.net/manage/user-notes.php?action=edit+29484 http://master.php.net/manage/user-notes.php?action=delete+29484 http://master.php.net/manage/user-notes.php?action=reject+29484
