PHP创建标签云函数，把标签生成一系列链接效果，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", $cloudTags ) . "\n";
20}
21?>
调用例子：
view sourceprint?
1<?php
2$arr = Array('CodeFans' => 35, 'Adobe' => 22, 'Background' =>43,
3'Blur' => 18, 'Canvas' => 33, 'Class' => 15, 'Design' => 8,'Encode' => 12, 'Encryption' => 30,
4'Extract' => 28, 'Filters' => 42);
5echo getCloud($arr, 12, 36);
6?>
