前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
<div class="codetitle"><a style="CURSOR: pointer" data="87949" class="copybut" id="copybut87949" onclick="doCopy('code87949')"> 代码如下:
<div class="codebody" id="code87949">
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( $tag ) ) . '';
} return join( "\n",$cloudTags ) . "\n";
}
