Note that this bindParam needs a variable as the second parameter.
Use bindValue if you want to bind a value, such an array item.

If you use any function to put value into an array, and bind it to the statement, PHP will fill NULLs on the binded field.

eg:

$st=$db->prepare('insert into xxx(x1,x2,x3) values(?,?,?)');
$st->bindParam(1, $data[0], SQLITE3_TEXT);
$st->bindParam(2, $data[1], SQLITE3_TEXT);
$st->bindParam(3, $data[2], SQLITE3_TEXT);

$data=explode(',','php,sometimes,woofs');

This will completely fail, and NULLs will be inserted on the table.

You need to manually assign every variable on the array. Any other function which completes it, will fail and NULLs are inserted.

$temp=explode(',','php,sometimes,woofs');
$data[0]=$temp[0];
$data[1]=$temp[1];
$data[2]=$temp[2];

Note:

$stmt->bindParam(1, 'lol', SQLITE3_TEXT);

That would trigger a fatal error as you cannot pass argument 2 by reference as it is a value.
