PHP創(chuàng)建標(biāo)簽云函數(shù)

    PHP創(chuàng)建標(biāo)簽云函數(shù)，把標(biāo)簽生成一系列鏈接效果，并大小不一，看上去有意思。
    01<?php
    02function getCloud($data = array(),$minFontSize = 12,$maxFontSize = 30 )
    03{
    04$minimumCount = min( array_values( $data ) );
    05$maximumCount = max( array_values( $data ) );
    06$spread = $maximumCount - $minimumCount;
    07$cloudHTML = '';
    08$cloudTags = array();
    09$spread == 0 && $spread = 1;
    10foreach( $data as $tag => $count )
    11{
    12$size = $minFontSize + ( $count - $minimumCount )
    13* ( $maxFontSize - $minFontSize ) / $spread;
    14$cloudTags[] = '
    16'' returned a count of ' . $count . '">'
    17. htmlspecialchars( stripslashes( $tag ) ) . '';
    18}
    19return join( "n", $cloudTags ) . "n";
    20}
    21?>
    調(diào)用例子：
    view sourceprint?
