本文實(shí)例講述了Zend Framework中Zend_Registry元件用法。分享給大家參考，如下：

1.物件登錄

入門(mén)案例：

<?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>";

? ?

結(jié)果為：

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

設(shè)定資料、取得資料

語(yǔ)法：

設(shè)定值Zend_Registry::set('index','value')

取得值Zend_Registry::get('index')

：效果等同於new的結(jié)果。

3.物件註冊(cè)表setInstance、getInstance

範(fàn)例：

<?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>";

? ?

結(jié)果：

<?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;

? ?

結(jié)果：

Mike
30
male

getInstance來(lái)取得值。

4.isRegistered()來(lái)實(shí)現(xiàn)索引是否有值的判斷。

案例：

<?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";
}

? ?

結(jié)果：

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

? ?

5.刪除靜態(tài)登錄

Zend_Registry::_unsetInstance()方法刪除靜態(tài)登錄

案例：

<?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";
}

? ?

刪除方法之後，之前的註冊(cè)資料就沒(méi)有了。

小結(jié)：

這就是Zend_Registry的幾個(gè)常用的方法與案例。透過(guò)註冊(cè)表可以實(shí)現(xiàn)許多普通變數(shù)無(wú)法實(shí)現(xiàn)的功能。

希望本文所述對(duì)大家基於Zend Framework框架的PHP程式設(shè)計(jì)有所幫助。
