PHP Getting SUM of Array Values While Comparing - php

Question

I have an array of Information States And Totals. I want to see how to get the Total of all the Totals for each state.
I know I have to use a loop but I am not sure which - what would I do?
This is what I have so far. It's making the array from a database.
$WorkFind = mysql_query(
"SELECT Customers.State, WorkOrders.Total
FROM WorkOrders
INNER JOIN Customers
ON WorkOrders.CID=Customers.ID
WHERE WorkOrders.Type <> 'Warranty'
AND (WorkOrders.Status <> 'Closed'
OR WorkOrders.Status <> 'Cancelled')
AND WorkOrders.TransferID='0'
ORDER BY Customers.State ASC");
while ($Work = mysql_fetch_array($WorkFind)) {
}
The while loop has made the array but I'm unsure what to put into it.
I'm using PHP 5.3 and MYSQL 5.2

Try this:
$WorkFind = mysql_query("SELECT Customers.State AS State, WorkOrders.Total AS Total -- ...");
$total = array();
while ($Work = mysql_fetch_array($WorkFind)) {
$state = $Work['State'];
if (!isset($total[$state])) {
$total[$state] = 0;
}
$total[$state] += $Work['Total'];
}
// format as simple table
echo '<table><tr><th>State</th><th>Total</th></tr>';
foreach ($total as $state_name => $state_total) {
echo '<tr><td>' . $state_name . '</td><td>' . $state_total . '</td></tr>';
}
echo '</table>';
