The example in this article describes how Zend Framework implements custom filters. Share it with everyone for your reference, the details are as follows:

Create a custom filter

Code:

<?php
require_once &#39;Zend/Filter/Interface.php&#39;;
class MyFilter implements Zend_Filter_Interface{
 public function filter($value){
  $badlist = array("梨","草莓","蘋果");
  for($i = 0;$i<count($badlist);$i++){
   $value = str_replace($badlist[$i], "*", $value);
  }
  return $value;
 }
}
$filter = new MyFilter();
$temp1 = "桔子真好吃";
$temp2 = "我喜歡吃蘋果";
$temp3 = "梨也不錯，但我最喜歡吃的是草莓！";
echo "內(nèi)容：".$temp1."<p>經(jīng)過過濾后為：";
echo $filter->filter($temp1);
echo "<p>";
echo "內(nèi)容：".$temp2."<p>經(jīng)過過濾后為：";
echo $filter->filter($temp2);
echo "<p>";
echo "內(nèi)容：".$temp3."<p>經(jīng)過過濾后為：";
echo $filter->filter($temp3);
echo "<p>";

Result:

Content: Oranges are so good Eat

After filtering: Oranges are so delicious

Content: I like to eat apples

After filtering: I like to eat *

Content : Pears are also good, but my favorite is strawberry!

After filtering: * is also good, but my favorite food is *!

Analysis:

After inheriting the interface, implement the filter method. Then instantiate this class and call this method. You can complete the content you want to filter.

I hope this article will be helpful to everyone’s PHP programming based on the Zend Framework framework.
