/*过滤器的简单使用方法及操作()*/

require_once("Zend/Loader.php");
//引入Filter的字符串转小写类 与 转大写类
Zend_Loader::loadClass("Zend_Filter_StringToLower");
Zend_Loader::loadClass("Zend_Filter_StringToUpper");
//实例化字符串转小写类 与 转大写类
$Filter = new Zend_Filter_StringToLower();
$Filter2 = new Zend_Filter_StringToUpper();
//设定需要转换的字符串
$Temp = 'ZHOUWUJIE     zhouwujie    ';
//转化方法filter();
$Result = $Filter -> filter($Temp);
$Result2 = $Filter2 -> filter($Temp);
echo $Result;
echo $Result2;
?>

复制代码 代码如下:

/*过滤器的使用方法及操作(过滤链)*/
require_once("Zend/Loader.php");
//过滤器的过滤链的使用载入过滤器和过滤器的方法类
Zend_Loader::loadClass("Zend_Filter");
Zend_Loader::loadClass("Zend_Filter_Htmlentities");
Zend_Loader::loadClass("Zend_Filter_StripTags");
//实例化过滤器后添加过滤器 addFilter(new 过滤器方法类名())
$Filter = new Zend_Filter();
$Filter //-> addFilter(new Zend_Filter_Htmlentities());
  -> addFilter(new Zend_Filter_StripTags());
$String = "链接";
$Result = $Filter -> filter($String);
echo $Result;
?>

/*自定义过滤器*/
require_once("Zend/Loader.php");
Zend_Loader::loadClass("Zend_Filter_Interface");
class MyFilter implements Zend_Filter_Interface
{
 public function filter($value)
 {
  $List = array('黄色','赌','毒');
  foreach ($List as $k => $v)
  {
   $value = str_replace($v, '*', $value);
  }
  return $value;
 }
}
$Filter = new MyFilter();
$String = '这条信息是黄色内容';
$String2 = '他今天去赌博了';
$String3 = '他今天去吸毒了';
echo "
