Hi Everyone!
I'm new to the board, I found out about this sight earlier last week I've been coding PHP for about two months now but I thought i'd probably learn new things alot quicker by joining some kind of community!
I've just got a small problem with this PHP tag cloud code i'm working on. The font size for the links of the cloud were coming out huge, i've traced it down the source of the problem which is the '$range' variable which is responsible for subtracting the highest value in the 'counts' field from my db from the lowest which is 57 - 1 . However when I echoed out this value the number is '563236'! i've tried to use the ceil() and floor() functions but to no avail. Can someone tell me what i'm doing wrong?
Thanks in advance!
$query = "SELECT
item AS tag,
count AS count
FROM tags
GROUP BY item
ORDER BY item ASC";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result))
{
$tags[$row['tag']] = $row['count'];
}
$maxSize = 250;
$minSize = 100;
$maxQty = max(array_values($tags));
$minQty = min(array_values($tags));
echo $maxQty."<br/>";
echo $minQty."<br/>";
$range = floor($maxQty - $minQty);
echo "range: ".$range;
if(0 == $range)
{
$range = 1;
}
foreach ($tags as $key => $value)
{
$size = ceil($minSize + (($value - $minQty) * $range));
echo '<li><a href="#" class="tag" style="font-size:'.$size.'%">'.$key.'</a>';
echo ' <span class="count">('.$value.')</span></li>';
echo '</ul>';
}
