parsing string and cutting out chunk

[stephdumais]

Is there a way to parse a string value, that is, seperating it into different elements via a common seperator, and then take out the last chunk?

To be more specific, I am doing this for a url:

value:
website.com/subdir/subdir/subdir/

I need a function that will split this value by the "/" seperators and strip out the last part (if there is nothing after the last slash, remove the next item):

website.com/subdir/subdir/

Am I making any sense? Can anyone help?
Thanks!

You could use something like this:

<?PHP
$str = "website.com/subdir/subdir/subdir/test";
$val = explode("/",$str);
$newval = "";
for ($i=0; $i<count($val)-1; $i++) {
	$newval .= $val[$i]."/";
}
echo $newval;
?>

This works great, except for when there is a slash at the end. Is there a way to make it work by ignorin the last slash if there is nothing after it?

Ok, found it: substr($str, 0, -1);

You might find [man]trim/man or [man]rtrim/man useful so such stripping as well.

There I go missing the obvious...thanks!
