[PHP + MySQL] Salvare dei valori in un campo timestamp

[piero.mac]

Se il timestamp e' UNIX, campo formato INT(10) UNSIGNED :

$data = "$year"."$day"."$month";

$query = "INSERT INTO tabella (timestamp) 
          VALUES (UNIX_TIMESTAMP('$data') )";

Se invece e' timestamp MySQL, campo formato TIMESTAMP:

$data = "$year"."$day"."$month";

$query = "INSERT INTO tabella (timestamp) 
          VALUES ('$data') ";
