Ever see those sections on websites where some links are bigger than
others? This is that! Simply passs an associative array of strings, and
"weight", then echo the result.
<?php
function gettaCloud( $data = array(), $minFontSize = 12, $maxFontSize = 30 )
{
$minimumCount = min($data);
$maximumCount = max($data);
$spread = $maximumCount - $minimumCount;
$cloudHTML = '';
$cloudTags = array();
$spread == 0 && $spread = 1;
foreach( $data as $tag => $count )
{
$size = $minFontSize + ( $count - $minimumCount )
* ( $maxFontSize - $minFontSize ) / $spread;
$cloudTags[] = '<a style="font-size: ' . floor( $size ) . 'px'
. '" class="tag_cloud" href="#" title="\'' . $tag .
'\' returned a count of ' . $count . '">'
. htmlspecialchars( stripslashes( $tag ) ) . '</a>';
}
return join( "\n", $cloudTags ) . "\n";
}
