I was wondering how I could remove a certain part of a url using PHP.
This is the exact url in questions:
http://www.mysite.com/link/go/370768/
I'm looking to remove the number ID into a variable.
Any help would be great, Thanks!

There are many (many!) ways of extracting a number from a string. Here's an example which assumes the URL starts with the format like http://www.mysite.com/link/go/<ID> and extracts the ID.
$url = 'http://www.mysite.com/link/go/370768/';
sscanf($url, 'http://www.mysite.com/link/go/%d', $id);
var_dump($id); // int(370768)

Use explode()
print_r(explode("/", $url));

You could use mod_rewrite inside of your .htaccess to internally rewrite this URL to something more friendly for PHP (convert /link/go/370768/ into ?link=370768, for example).

I suspect that you are using some kind of framework. There are two ways to check the $_GET variables:
print_r($_GET);
or check the manual of the manual of the framework and see how the GET/POST is passed internally, for example in CakePHP you have all parameters save internally in your controller you can access them like that:
$this->params['product_id'] or $this->params['pass']
There is another solution which is not very reliable and professional but might work:
$path = parse_url($url, PHP_URL_PATH);
$vars = explode('/', $path);
echo $vars[2];
$vars should contain array like this:
array (
0 => link
1 => go
2 => 370768
)

$_GET is internall PHP array that contains all variables sent in the URL: php.net/manual/en/reserved.variables.get.php
mod_rewriteto alter your URL to something nicer.
