Need help to understand a code

[Ashickur Rahman Noor <ashickur.noor@xxxxxxxxx>]

Hi all

I need some help to understand a code. The code is like this

$result = mysql_query($sSQL) or die("err: " . mysql_error().$sSQL);
>     if($row = mysql_fetch_array($result))
>                         {
>       foreach($row as $key =>$value){ $$key=$value;}
>     }
>

I don't get the code from the foreach loop.
