the statement reads like:

^ match start of string
( I want the portion in brackets returned to me
.* anything
\/\/   then two slashes //
[^\/]*  anything that is not a slash
) end of the part I want returned
\/  then a slash

returns:  HTTP://website.com
<?php
$url = "HTTP://website.com/folder/folder/page.php?car=Ford&size=compact#top";
preg_match("/^(.*\/\/[^\/]*)\//",$url,$matches);
echo $matches[1];
//var_dump($matches);
?>

I am using php 5.3.3 in Ubuntu linux.  Works in a browser and on the command line.

Did it not return anything or did it return something that was not what you expected.

I do not understand what you mean by "anchor portion" but PHP has a built-in function to do this.
http://www.laprbass.com/RAY_temp_rgb192.php
Outputs something like:
Array
(
    [scheme] => HTTP
    [host] => website.com
    [path] => /folder/folder/page.php
    [query] => car=Ford&size=compact
    [fragment] => top
)
<?php // RAY_temp_rgb192.php
$url = 'HTTP://website.com/folder/folder/page.php?car=Ford&size=compact#top';
$arr = parse_url($url);
echo "<pre>";
print_r($arr);
