复制代码 代码如下:
function getCloud( $data = array(), $minFontSize = 12, $maxFontSize = 30 )
{
$minimumCount = min( array_values( $data ) );
$maximumCount = max( array_values( $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
. href=# title=\ . $tag .
\ returned a count of . $count . >
. htmlspecialchars( stripslashes( $tag ) ) . </a>;
}
return join( \n, $cloudTags ) . \n;
}
