MySQL mysql num rows

0 votes

The variable: "$num_rows" is not even being set and has no value. 

$result2 = mysql_query("SELECT * FROM `mycity_vehicles` WHERE `id` = '$vehID'");
while($row2 = mysql_fetch_array($result2))
$num_rows = mysql_num_rows($result2);
{
    if(empty($num_rows)) {
        echo "empty";
    }
    else {
        echo $num_rows;
    }

Can someone please help me with this?
