PHP & HTML - ricordare selezione <option>

[zUmBo!]

Salve a tutti!

in pratica sto cercando di far "ricordare ad uno script php" il valore di una selezione </option> da un form...


Per far ciò, avrei bisogno di creare un nome di variabile da un prefisso opt_ e dal valore di un'altra variabile, in questo caso il valore di $provincia ...

...facciamo così, vio posto il codice, così è tutto più chiaro...ovviamente la parte inserita tra i commenti è errata.

Voi, come fareste?

Codice PHP:

if (!$provincia){$opt_scegli="selected";
}/*else{$opt_$provincia="selected";}*/
                      <select name=\"provincia\" class=\"campiform\">
                        <option $opt_scegli>Scegli la provincia...</option>
