if(!preg_match("/^(http)+(:\\/\\/)+[A-Za-z0-9\-_]+\\.+[A-Za-z0-9\.\/%&=\?\-_]+$/i", $company_web)) {
            $is_error = 1;
            $error_message .= '<li>you have typed an invalid company web address 1</li>';
            $error_count++;
        }

filter_var('example.com', FILTER_VALIDATE_URL);

Your current pattern also allows for httphttphttphttphttp://://://://://://://://://://://_.. as a "valid" URL. There have been many posts in this forum on the subject of validating URLs and my first suggestion would be to point you towards the search function, so you can see if anything already posted here will be useful to you.
