regex match help please

[sde]

i'm making a script that walks through directories..

i have it going up through directories and reading fine, .. but the problem is coming back down.

../ is not an option in this script.

what i need to do is use regular expressions 'preg_replace()' to take off the last directory of the path string.

PHP Code:

<?
$path="./path/to/somwhere/";

// here i need a function to modify the path
// to be: ./path/to/
?>

a regular expression would do the trick, but i'm not sure how to approach matching the last part of the string.

this looks like a job for strrpos() and substr() to me.

i dont' think the matching capabilities are there for that combination. i've used strstr,strpos,&substr extensivily in other scripts, .. but i need to cut everything after the second to last forward slash out.

that is why i thought i needed regext .. so i could match the end of the string to the second slash back.

you've got all the tools. just put them together.
untested, off the top of my head:

PHP Code:

<?
  $s = "/the/path/removeme/";

  $s = substr($s, 0, strrpos($s, "/"));  // removes last slash
  $s = substr($s, 0, strrpos($s, "/") + 1);  // removes "removeme"

?>
