Recalling random values from mysql table - php

Question

I'm fairly new to php and mysql and I'm on the home stretch of finishing my page but I've been banging my head on the keyboard all day trying to figure out how to fix this problem. I've set up a php script to run as a cron even every 24 hours. The script assigns a random number between 10 and 30 to each field in my table. That works fine and every time I load the script the values change.
The problem I'm having is when I try to use those values. The result keeps printing as the word Array instead of the number in the table. So I'll give you some snippets of the code I'm running here. This is the cron event.
?php
$con = mysql_connect("localhost","username","pass");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dbname", $con);
$random= rand(10, 30);
mysql_query("UPDATE winners SET pool= '$random'");
mysql_close($con);
And here is the script to call up the values.
php?
$db = mysql_connect('localhost','username','pass') or die("Database error");
mysql_select_db('dbname', $db);
$query = "SELECT pool FROM winners";
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($result))
if ( $row % 2 )
{
echo "<h4>Result 1</h4>";
echo "$row";
echo "<br />";
}
else
{
echo "<h4>Result 2</h4>";
echo "<br />";
}
I've tried every possible variation I can think of to this code but all I can get is it to echo either Array or Resource #9. Any insight into this would be greatly appreciated.

Answer 1

You do not want to echo the content of $row, which contains all data returned for the current line you've fetched from the database when calling mysql_fetch_array().
Instead, you want to access the content of $row's pool item :
echo $row['pool'];
You should probably take a closer look at the manual page for mysql_fetch_array(), and the examples it contains.
Note that you'll probably also want to modify the condition in the following line :
if ( $row % 2 )
You probably don't want the test to be done on $row, but on an item it contains.

Answer 2

$query = "SELECT pool FROM winners";
$result = mysql_query($query) or die(mysql_error());
while ($row = mysql_fetch_array($result))
{
if ( $row['pool'] % 2 )
{
echo "<h4>Result 1</h4>";
echo "$row['pool']";
echo "<br />";
}
else
{
echo "<h4>Result 2</h4>";
echo "<br />";
}
}
Hope this helps.
