UPDATED

While()
{
$a[] = row[‘a’];

Can,i pass this in fql SELECT query?

Answer 1

No you can’t, but you can do something like:

$a = "";
while() {
    if ($a != "")
        $a .= row['a'];
    else
        $a .= "," . row['a'];
}

and pass that as a list in an IN clause.

Note that I have no idea what you want to do with it, and since your code looks like some kind of pseudo code, I’ve tried replying with the same syntax. I have no idea how you end that while loop or get anything but the same value from $row['a'].
