php云标签的简单范例

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);
?>
