$arraydiciottina=array(1,2,3,4,5,6,7,8,9,10,11,12, 13,14,15,16,17,18);

$elements = $arraydiciottina;

$array = generate($elements, 0);

print_r ($array);

il cod mi genera questo:

mentre io vorrei qualcosa di quest'altro tipo...

COPPIE con numeri componenti PARI E DISPARI

es. [0] => 1.2 ecc...

COPPIE con numeri componenti SOLO PARI

es. [22] => 2.8 ecc...

COPPIE con numeri componenti SOLO DISPARI

es. [1] => 1.3 ecc...

Di quale cod evrei bisogno per fare questo tipo di particolare "scrematura..." se lo sapete?

Grazie infinite
