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

1. Object registry

Startup case:

<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass(&#39;Zend_Registry&#39;);
$member = array(
  "姓名"=>"張三",
  "性別"=>"女",
  "年齡"=>"13",
  "職業(yè)"=>"學(xué)生",
  "愛(ài)好"=>"玩游戲",
  "血型"=>"AB"
  );
$registry = new Zend_Registry($member);
echo "姓名為：";
echo $registry["姓名"];
echo "<p>";
echo "性別為：";
echo $registry["性別"];
echo "<p>";
echo "年齡為：";
echo $registry["年齡"];
echo "<p>";
echo "職業(yè)為：";
echo $registry["職業(yè)"];
echo "<p>";
echo "愛(ài)好為：";
echo $registry["愛(ài)好"];
echo "<p>";

Result For:

姓名為：張三
性別為：女
年齡為：13
職業(yè)為：學(xué)生
愛(ài)好為：玩游戲

2.set() method and get() method to set data and get data

Syntax:

Set the value Zend_Registry::set('index','value')
Get the value Zend_Registry::get('index')

Case:

<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass(&#39;Zend_Registry&#39;);
$member = array(
  "姓名"=>"張三",
  "性別"=>"女",
  "年齡"=>"13",
  "職業(yè)"=>"學(xué)生",
  "愛(ài)好"=>"玩游戲",
  "血型"=>"AB"
  );
Zend_Registry::set("registry",$member);
$registry = Zend_Registry::get("registry");
echo "姓名為：";
echo $registry["姓名"];
echo "<p>";
echo "性別為：";
echo $registry["性別"];
echo "<p>";
echo "年齡為：";
echo $registry["年齡"];
echo "<p>";
echo "職業(yè)為：";
echo $registry["職業(yè)"];
echo "<p>";
echo "愛(ài)好為：";
echo $registry["愛(ài)好"];
echo "<p>";

Explanation: The effect is equivalent to the result of new.

3. Object registry setInstance, getInstance

Example:

<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass(&#39;Zend_Registry&#39;);
$registry = new Zend_Registry();
Zend_Registry::setInstance($registry);
$registry->name = "Mike";
$registry->age = "30";
$registry = Zend_Registry::getInstance();
echo $registry->name;
echo "<p>";
echo $registry->age;
echo "<p>";
$registry->sex = "male";
echo $registry->sex;

Result:

Mike
30
male

Explanation: Through the setInstance method, you can set the value in the form of an object, and then obtain the value through getInstance.

4.isRegistered() to determine whether the index has a value.

Case:

<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass(&#39;Zend_Registry&#39;);
Zend_Registry::set("name","張三");
if(Zend_Registry::isRegistered("name")){
  echo "對(duì)象注冊(cè)表name已經(jīng)定義";
}else{
  echo "對(duì)象注冊(cè)表name沒(méi)有定義";
}
echo "<p>";
if(Zend_Registry::isRegistered("age")){
  echo "對(duì)象注冊(cè)表age已經(jīng)定義";
}else{
  echo "對(duì)象注冊(cè)表age沒(méi)有定義";
}

Result:

對(duì)象注冊(cè)表name已經(jīng)定義
對(duì)象注冊(cè)表age沒(méi)有定義

Description:

If defined, it can be detected.

5. Delete the static registry

Zend_Registry::_unsetInstance() method deletes the static registry

Case:

<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass(&#39;Zend_Registry&#39;);
Zend_Registry::set("name","張三");
echo "執(zhí)行操作前：";
echo "<p>";
if(Zend_Registry::isRegistered("name")){
  echo "對(duì)象注冊(cè)表name已經(jīng)定義";
}else{
  echo "對(duì)象注冊(cè)表name沒(méi)有定義";
}
echo "<p>";
if(Zend_Registry::isRegistered("age")){
  echo "對(duì)象注冊(cè)表age已經(jīng)定義";
}else{
  echo "對(duì)象注冊(cè)表age沒(méi)有定義";
}
Zend_Registry::_unsetInstance("name");
echo "<p>";
echo "執(zhí)行操作后：";
echo "<p>";
if(Zend_Registry::isRegistered("name")){
  echo "對(duì)象注冊(cè)表name已經(jīng)定義";
}else{
  echo "對(duì)象注冊(cè)表name沒(méi)有定義";
}
echo "<p>";
if(Zend_Registry::isRegistered("age")){
  echo "對(duì)象注冊(cè)表age已經(jīng)定義";
}else{
  echo "對(duì)象注冊(cè)表age沒(méi)有定義";
}

Result:

執(zhí)行操作前：
對(duì)象注冊(cè)表name已經(jīng)定義
對(duì)象注冊(cè)表age沒(méi)有定義
執(zhí)行操作后：
對(duì)象注冊(cè)表name沒(méi)有定義
對(duì)象注冊(cè)表age沒(méi)有定義

Explanation: After executing the deletion method, the previous registration information will be gone.

Summary:

These are several commonly used methods and cases of Zend_Registry. Many functions that cannot be achieved with ordinary variables can be achieved through the registry.

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