使用mysql_fetch_assoc获取数组

Question

$query = mysql_query("SELECT Name from lottery");
// Make All Lotteries Into An Array
$queryarray = mysql_fetch_array($query);
// For Each Lottery, Store the Name of It in $lottery
foreach ($queryarray as $lottery) {
    // Select IDs of Tickets in Current Selected Lottery ($lottery)
    $ticketquery = mysql_query("SELECT id FROM tickets WHERE lottery='$lottery'");
    // Create an Array from the IDS
    $ticketarray = mysql_fetch_assoc($ticketquery);
    // Select A Random ID, This Is Our Winner Ticket
    $winner = $ticketarray[array_rand($ticketarray)];
}

When I run this, however, I get this error:

---

"Warning: array_rand() [function.array-rand]: First argument has to be an array in public_html/php/lotterypick.php on line 25"

---

I have tried to replace mysql_fetch_assoc with mysql_fetch_array and that hasn't helped much either. Just given me the same error. Any ideas? Thanks.

Line 25: $winner = $ticketarray[array_rand($ticketarray)];

Answer 1

Writing the code as:

while($lottery = mysql_fetch_array($query)){...}

would solve the problem.
