Regular Expressions

Hello I have a list of websites which i wish to "prefix", by truncating them at the third occurence of '/' (including the 2 for http://)

 

so like:

 

$str = 'http://www.google.com/analytics/blah/blah.html';

function truncate($str)
{

}
echo truncate($str);
//would print http://www.google.com

 

 

thanks in advance.

You could do something like this:

$string = "http://www.google.com/analytics/blah/blah.html";
$pos = strpos($string, "/", 7);
$newstring = substr($string, 7, strlen($string)-7);

 

7 is how long the "http://" and if there is always going to be three, that will always be the there, right?
