The example in this article describes the usage of Zend Framework front-end controller. Share it with everyone for your reference, the details are as follows:

Common methods

1.getInstance()

Function: Used to obtain the front-end controller instance.

$front = Zend_Controller_Front::getInstance();

Executing the above code will create a front-end controller instance.

$dire = $front->getControllerDirectory();

Environment accessor method

1.resetInstance()
Function: Clear all current settings

2.(set|get)DefaultControllerName()

3.(set|get)DefaultActionName()

Front-end controller parameters

1.setParam(name,name,value)
Function: Set a single parameter value with value A single parameter name

2.setParams(array $params)
Function: Set multiple parameters at once through an associative array

3.getParam($name)
Function: Get a single parameter through the $name identifier

4.getParams()
Function: Get the entire parameter list at one time

5.clearParams()
Function: Clear a parameter (pass Enter a single string), multiple parameters (pass in an array), all parameters (no parameters)

Example:

<?php
require_once &#39;Zend/Controller/Front.php&#39;;    //加载Zend_Controller_Front类
$front = Zend_Controller_Front::getInstance();  //获取前端控制器实例
$front->setParam(&#39;name&#39;,&#39;张三&#39;);        //设定前端控制器参数
$name = $front->getParam(&#39;name&#39;);        //获取设定的参数
echo $name;
echo "<p>";
$array = array(
  &#39;g_n&#39;=>&#39;联想&#39;,
  &#39;g_c&#39;=>&#39;5000&#39;,
  &#39;g_a&#39;=>&#39;北京&#39;,
  &#39;g_p&#39;=>&#39;联想集团&#39;
);
$front->setParams($array);
$g = $front->getParams();
foreach($g as $k=>$v){
  echo $k."的值为:".$v;
  echo "<p>";
}
$front->clearParams();
$last = $front->getParams();
foreach($last as $k=>$v){
  echo $k."的值为:".$v;
  echo "<p>";
}

The result is:

张三
name的值为:张三
g_n的值为:联想
g_c的值为:5000
g_a的值为:北京
g_p的值为:联想集团

Because the parameters are cleared, no data is output during the second call.

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