Need foreach Help

[Sharif]

I am trying to create a string out of a array variable. Here is an example:

$var = array(0=> '', 1 => 'a', 2 => 'b', 3 => 'c', 4 => 'd');
$string = '';
foreach($var as $key=>$value)
{
   $string.= $value . '/';
}
echo 'www.mysite.com/' . $string;

And it comes out like this:
www.mysite.com//a/b/c/d/

And if I change $var to = array(0 => '');
It comes out like:
www.mysite.com//

How can I get the formatting right it shows up like:
www.mysite.com/a/b/c/d/

try

echo 'www.mysite.com' . $string;

Ok this is just not working. Basically I am trying to seperate values that are held in $PATH_INFO;

I want to be able to take those values, and add them onto the end of www.mysite.com/

How can I do this?

$var = array(0=> '', 1 => 'a', 2 => 'b', 3 => 'c', 4 => 'd');
$string = '';
foreach($var as $key=>$value)
{
if (!empty($value))
   $string.= $value . '/';
}
echo 'www.mysite.com/' . $string;
