Removing part from a string

[crep]

I have a string which contains a path and I need to remove the last directory from the string. For example:

I have string which contains following path: /www/htdocs/folder/subfolder

And I need to get rid of /subfolder, so that final string would look like: /www/htdocs/folder

How can I do this?

And the 'subfolder' isn't static, it's chancing value.

Thanks for your help 🙂

hmm try this im sure these an easyer way but im tired

<?
$string = "/www/htdocs/folder/subfolder";
$split = array();
$split = explode("/", $string);
$int = sizeof($split);
$int2 = "$int" - "1";
$string = "";
for($i=1; $i<$int2; $i++){
$string .= "/$split[$i]";
}
/*you dont need to print it of cource you can continue using $string just like normal*/
echo "$string<br>";
?>

Another solution(a little simpler I quess):

$path ='/www/htdocs/folder/subfolder';
$len=strlen($path);
while ($path{$len}!="/") $len--;
$string=substr($path,0,$len);
