本文介绍下，php实现云标签的一个简单例子，老外写的，很简炼。有需要的朋友，可以参考下人家的写法。php 云标签的例子，代码如下：
$value) { // calculate font-size // find the $value in excess of $min_qty // multiply by the font-size increment ($size) // and add the $min_size set above $size = round($min_size + (($value - $min_qty) * $step)); echo '' . $key . ' '; }}//调用示例$tags = array('weddings' => 32, 'birthdays' => 41, 'landscapes' => 62, 'ham' => 51, 'chicken' => 23, 'food' => 91, 'turkey' => 47, 'windows' => 82, 'apple' => 27);printtagcloud($tags);?>
