     Converte una stringa in un array. Se viene passato
     il parametro opzionale <parameter>split_length</parameter>, l'array
     restituito sarà composto da segmenti, ciascuno della lunghezza di
     <parameter>split_length</parameter> caratteri, in caso contrario ciascun segmento
     sarà lungo un carattere.
    </para>
    <para>
     &false; è restituito se <parameter>split_length</parameter> è minore
     di 1. Se <parameter>split_length</parameter> supera la lunghezza
     di <parameter>string</parameter>, sarà restituita l'intera stringa
     come primo (ed unico) elemento dell'array.
