Hey all,

Nevermind this. I just solved it myself.
I found out it does not matter when you decalre a variable as global (other 
than I guess before you use it)
So I made my function this way.
function key_value ( $mysql  )  {
         if ( $sao_row = $mysql -> fetchRow() )  {
                 do {
                         global ${"$sao_row[0]"};
                         ${"$sao_row[0]"} = $sao_row[1]; // Create a 
variablle to pull the radio variable name
                 }       while ( $sao_row = $mysql -> fetchRow() );
         }
}

and it works like a charm.
