PHP創建標簽雲函數

   PHP創建標簽雲函數,把標簽生成一系列鏈接效果,並大小不一,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?>
