復制代碼 代碼如下:
<?php
/*過濾器的簡單使用方法及操作()*/
require_once("Zend/Loader.php");
//引入Filter的字符串轉小寫類 與 轉大寫類
Zend_Loader::loadClass("Zend_Filter_StringToLower");
Zend_Loader::loadClass("Zend_Filter_StringToUpper");
//實例化字符串轉小寫類 與 轉大寫類
$Filter = new Zend_Filter_StringToLower();
$Filter2 = new Zend_Filter_StringToUpper();
//設定需要轉換的字符串
$Temp = 'ZHOUWUJIE zhouwujie ';
//轉化方法filter();
$Result = $Filter -> filter($Temp);
$Result2 = $Filter2 -> filter($Temp);
echo $Result;
echo $Result2;
?>
復制代碼 代碼如下:
<?php
/*過濾器的使用方法及操作(過濾鏈)*/
require_once("Zend/Loader.php");
//過濾器的過濾鏈的使用載入過濾器和過濾器的方法類
Zend_Loader::loadClass("Zend_Filter");
Zend_Loader::loadClass("Zend_Filter_Htmlentities");
Zend_Loader::loadClass("Zend_Filter_StripTags");
//實例化過濾器后添加過濾器 addFilter(new 過濾器方法類名())
$Filter = new Zend_Filter();
$Filter //-> addFilter(new Zend_Filter_Htmlentities());
-> addFilter(new Zend_Filter_StripTags());
$String = "<a href='#'>鏈接</a>";
$Result = $Filter -> filter($String);
echo $Result;
?>
復制代碼 代碼如下:
<?php
/*自定義過濾器*/
require_once("Zend/Loader.php");
Zend_Loader::loadClass("Zend_Filter_Interface");
class MyFilter implements Zend_Filter_Interface
{
public function filter($value)
{
$List = array('黃色','賭','毒');
foreach ($List as $k => $v)
{
$value = str_replace($v, '*', $value);
}
return $value;
}
}
$Filter = new MyFilter();
$String = '這條信息是黃色內容';
$String2 = '他今天去賭博了';
$String3 = '他今天去吸毒了';
echo "<hr>過濾內容<br>";
echo $Filter -> filter($String) . "<br>";
echo $Filter -> filter($String2) . "<br>";
echo $Filter -> filter($String3) . "<br>";
?>
