How to implement custom filters in Zend Framework

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){
  $badlist = array("梨","草莓","苹果");
  for($i = 0;$i<count($badlist);$i++){
   $value = str_replace($badlist[$i], "*", $value);
  }
  return $value;
 }
}
$filter = new MyFilter();
$temp1 = "桔子真好吃";
$temp2 = "我喜欢吃苹果";
$temp3 = "梨也不错，但我最喜欢吃的是草莓！";
echo "内容：".$temp1."<p>经过过滤后为：";
echo $filter->filter($temp1);
echo "<p>";
echo "内容：".$temp2."<p>经过过滤后为：";
echo $filter->filter($temp2);
echo "<p>";
echo "内容：".$temp3."<p>经过过滤后为：";
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.
