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

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

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?>
