Correct way of php concatenation
<p>Hey is this the correct way to do concatenation? it does not seem to want to work for me!.</p>

<pre><code>        $driver1points = 0;
        $driver2points = 0;
        $driver3points = 0;
        $driver4points = 0;

        for($i = 1; $i &lt;= 4; $++){
            if(${"driver".$i} == $driverrace["fastestlap"]) {
                ${"driver". $i ."points"} += $driver_points_system["fastestlap"];
                $racepoints += $team_points_system["fastestlap"];
                break;
            }
         }
</code></pre>
