How to implement custom filters in Zend Framework

This article describes the method of implementing custom filters by Zend Framework. Share it for your reference, as follows:

Create a custom filter

Code:

<?php
require_once 'Zend/Filter/';
class MyFilter implements Zend_Filter_Interface{
 public function filter($value){
  $badlist = array("pear","strawberry","apple");
  for($i = 0;$i<count($badlist);$i++){
   $value = str_replace($badlist[$i], "*", $value);
  }
  return $value;
 }
}
$filter = new MyFilter();
$temp1 = "Oranges are delicious";
$temp2 = "I like eating apples";
$temp3 = "Pears are not bad, but my favorite thing to eat is strawberries!";
echo "content:".$temp1."<p>Filtered as:";
echo $filter-&gt;filter($temp1);
echo "&lt;p&gt;";
echo "content:".$temp2."<p>Filtered as:";
echo $filter-&gt;filter($temp2);
echo "&lt;p&gt;";
echo "content:".$temp3."<p>Filtered as:";
echo $filter-&gt;filter($temp3);
echo "&lt;p&gt;";

result:

Content: Oranges are delicious

After filtering, it is: Oranges are delicious

Content: I like eating apples

After filtering, I like to eat*

Content: Pears are not bad, but my favorite thing to eat is strawberries!

After filtering, it is: * is not bad, but my favorite thing to eat is *!

analyze:

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.
