Shouldn't that be:
while($data=mysql_fetch_array($result))
{
//SSLT
}
NOTE: Added ) and changes $query to $result

Subject: [PHP] MySQL Query Result Question
I have the following query:
$query = "SELECT d.utilization, d.capacity_date, d.day, i.id,
i.interface, cd.date, cd.id ";
$query .= "FROM (capacity_data as d LEFT JOIN interfaces as i ON
d.interface = i.id) ";
$query .= "LEFT JOIN capacity_date as cd ON d.capacity_date=cd.id ";
$query .= "WHERE i.router = '$cmts[$i]' AND cd.date >= '$useDate'
";
$query .= "ORDER BY i.interface,cd.date DESC";
if(!$result = mysql_query($query)) die(mysql_error());
while($data=mysql_fetch_array($query)
{
//SSLT
}
The query itself runs just fine. However, I've run into a problem with
the loop I've created. During one of the iterations, the query returns
no data so during the subsequent loop the previous query's results is
used in it's place. I do not want this to happen. What is the best way
to destroy $result before I run the query?
