Question

I wrote a PHP script that retrieves values from a MySQL Query. I used mysql_fetch_array to add the results to an array. I am trying to select a random value from the array, however array_rand doesn’t seem to work. My code is below:

<?php 
session_start();
ob_start();
require_once 'includes/db_connection.php';
require_once 'includes/contest.php';
require_once 'includes/survey.php';
require_once 'includes/poll.php';
require_once 'includes/clients.php';
require_once 'includes/user.php';
//Select All Entries from Contest and Save as Array
//Select 
mysql_connect(localhost,s2ktest_s2kuser, Bc33iyZYQWgUmguBehPI);
$dbname = 's2ktest_s2k';
mysql_select_db($dbname);
$contestid = 20;
$query = "SELECT UserID FROM Contest_Entered WHERE ContestID = $contestid";
//Save Result
$result = mysql_query($query) or die(mysql_error());
//Save All Contest Entries in Array
$entries = mysql_fetch_array($result) or die(mysql_error());

//Output all Rows
//While Each Entry in the Array is a Value
while($entries = mysql_fetch_array($result))
{
echo $entries;
echo "</br>";
}
echo array_rand($entries);
//mysql_free_result($result);
?>

Maybe because you don’t have any array…
The while is only generating one row at the time.

while($entries = mysql_fetch_array($result))
 {
  echo $entries;
  $arr[] = $entries;
  echo "</br>";
 }
 echo array_rand($arr);
