Question

I have this Associative Array :

$Fields = array("row0"=>"Yahoo ID", "row1"=>"MSN ID", "row2"=> "Gtalk ID");

on the other side, I have this SQL query :

SELECT YahooID, MSNID, GTalkID From UserTable WHERE Username = '$Username' LIMIT 1;

the result maybe vary, because some users only have Yahoo ID and some have others. for example if I have this result :

$row[0] = NONE //means YahooID = NONE
$row[1] = [e-mail]
$row[2] = [e-mail]

then how to have this as an output (echo) :

MSN ID = [e-mail]

Gtalk ID = [e-mail]

since Yahoo ID is not exist, then the result will be MSN and Gtalk only. ‘MSN ID’ and ‘Gtalk ID’ is variable from Associative Array, while ‘[e-mail]’ and ‘[e-mail]’ from SQL result.

thanks!

$Fields = array();
while ($row = $result->fetch_assoc()) {
    if (! empty($row[0])) $Fields['MSN ID'] = $row[0];
    if (! empty($row[1])) $Fields['GTalk ID'] = $row[1];
    if (! empty($row[2])) $Fields['Yahoo ID'] = $row[2];
}

foreach ($Fields as $k => $v)
{
    echo "$k = $v" . PHP_EOL;
}
