《PHP應(yīng)用：Zend Framework入門教程之Zend_Registry組件用法詳解》要點(diǎn)：
本文介紹了PHP應(yīng)用：Zend Framework入門教程之Zend_Registry組件用法詳解，希望對(duì)您有用。如果有疑問，可以聯(lián)系我們。
本文實(shí)例講述了Zend Framework中Zend_Registry組件用法.分享給大家供大家參考,具體如下：PHP應(yīng)用
1.對(duì)象注冊(cè)表PHP應(yīng)用
入門案例：PHP應(yīng)用
<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass('Zend_Registry');
$member = array(
"姓名"=>"張三",
"性別"=>"女",
"年齡"=>"13",
"職業(yè)"=>"學(xué)生",
"愛好"=>"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 "愛好為：";
echo $registry["愛好"];
echo "<p>";
結(jié)果為：PHP應(yīng)用
姓名為：張三 性別為：女 年齡為：13 職業(yè)為：學(xué)生 愛好為：玩游戲
2.set()方法和get()方法設(shè)置數(shù)據(jù)、獲取數(shù)據(jù)PHP應(yīng)用
語(yǔ)法：PHP應(yīng)用
設(shè)置值Zend_Registry::set('index','value')
獲取值Zend_Registry::get('index')PHP應(yīng)用
案例：PHP應(yīng)用
<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass('Zend_Registry');
$member = array(
"姓名"=>"張三",
"性別"=>"女",
"年齡"=>"13",
"職業(yè)"=>"學(xué)生",
"愛好"=>"玩游戲",
"血型"=>"AB"
);
Zend_Registry::set("registry",$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 "愛好為：";
echo $registry["愛好"];
echo "<p>";
說明：效果等同于new的結(jié)果.PHP應(yīng)用
3.對(duì)象注冊(cè)表setInstance、getInstancePHP應(yīng)用
例子：PHP應(yīng)用
<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass('Zend_Registry');
$registry = new Zend_Registry();
Zend_Registry::setInstance($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：PHP應(yīng)用
Mike 30 male
說明：通過setInstance方法,就可以用對(duì)象的方式設(shè)置其中的值了,然后通過getInstance來獲取值.PHP應(yīng)用
4.isRegistered()來實(shí)現(xiàn)索引是否有值的判斷.PHP應(yīng)用
案例：PHP應(yīng)用
<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass('Zend_Registry');
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沒有定義";
}
結(jié)果：PHP應(yīng)用
對(duì)象注冊(cè)表name已經(jīng)定義 對(duì)象注冊(cè)表age沒有定義
說明：PHP應(yīng)用
如果定義了,可以檢測(cè)出來.PHP應(yīng)用
5.刪除靜態(tài)注冊(cè)表PHP應(yīng)用
Zend_Registry::_unsetInstance()方法刪除靜態(tài)注冊(cè)表PHP應(yīng)用
案例：PHP應(yīng)用
<?php
require_once("Zend/Loader.php");
Zend_Loader::loadClass('Zend_Registry');
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沒有定義";
}
結(jié)果：PHP應(yīng)用
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沒有定義 執(zhí)行操作后： 對(duì)象注冊(cè)表name沒有定義 對(duì)象注冊(cè)表age沒有定義
說明：執(zhí)行完刪除方法之后,之前的注冊(cè)信息就沒有了.PHP應(yīng)用
小結(jié)：PHP應(yīng)用
這就是Zend_Registry的幾個(gè)常用的方法與案例.通過注冊(cè)表可以實(shí)現(xiàn)很多普通變量無法實(shí)現(xiàn)的功能.PHP應(yīng)用
