Zend Framework Introductory Tutorial Zend_registry component Usage _php examples

This example describes the usage of Zend_registry components in the Zend Framework. Share to everyone for your reference, specific as follows:

1. Object Registration Form

Getting Started case:

<?php
require_once ("zend/loader.php");
Zend_loader::loadclass (' zend_registry ');
$member = Array (
  "name" => "John", "
  gender" => "female",
  "age" => "," "
  occupation" => "student",
  "hobby" => "Play games",
  "Blood type" => "AB"
  );
$registry = new Zend_registry ($member);
echo "name is:";
echo $registry ["name"];
echo "<p>";
echo "Sex is:";
echo $registry ["gender"];
echo "<p>";
echo "Age is:";
echo $registry ["age"];
echo "<p>";
echo "Occupation for:";
echo $registry ["occupation"];
echo "<p>";
echo "Hobby for:";
echo $registry ["hobby"];
echo "<p>";

The results are:

The name is: John
sex is: The female
age is: The occupation is: the
student
hobby is: plays the game

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

Grammar:

Set value Zend_registry::set (' Index ', ' value ')
Get value Zend_registry::get (' index ')

Case:

<?php
require_once ("zend/loader.php");
Zend_loader::loadclass (' zend_registry ');
$member = Array (
  "name" => "John", "
  gender" => "female",
  "age" => "," "
  occupation" => "student",
  "hobby" => "Play games",
  "Blood type" => "AB"
  );
Zend_registry::set ("Registry", $member);
$registry = Zend_registry::get ("registry");
echo "name is:";
echo $registry ["name"];
echo "<p>";
echo "Sex is:";
echo $registry ["gender"];
echo "<p>";
echo "Age is:";
echo $registry ["age"];
echo "<p>";
echo "Occupation for:";
echo $registry ["occupation"];
echo "<p>";
echo "Hobby for:";
echo $registry ["hobby"];
echo "<p>";

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

3. Object Registry Setinstance, getinstance

Example:

<?php
require_once ("zend/loader.php");
Zend_loader::loadclass (' zend_registry ');
$registry = new Zend_registry ();
Zend_registry::setinstance ($registry);
$registry->name = "Mike";
$registry->age = "a";
$registry = Zend_registry::getinstance ();
echo $registry->name;
echo "<p>";
echo $registry->age;
echo "<p>";
$registry->sex = "male";
Echo $registry->sex;

Results:

Mike
Male

Note: By using the Setinstance method, you can set the value in the object's way, and then getinstance to get the value.

4.isRegistered () to realize whether the index has a value of judgment.

Case:

<?php
require_once ("zend/loader.php");
Zend_loader::loadclass (' zend_registry ');
Zend_registry::set ("name", "John");
if (zend_registry::isregistered ("name")) {
  Echo Object Registry name is already defined;
} else{
  echo "Object registry name is not defined";
}
echo "<p>";
if (zend_registry::isregistered ("Age")) {
  Echo Object Registry age is already defined;
} else{
  echo "Object Registry age is not defined";
}

Results:

Object Registry name already defined
Object Registry age not defined

Description

If it is defined, it can be detected.

5. Delete static registry

Zend_registry::_unsetinstance () method deletes the static registry

Case:

<?php
require_once ("zend/loader.php");
Zend_loader::loadclass (' zend_registry ');
Zend_registry::set ("name", "John");
echo "Before performing operation:";
echo "<p>";
if (zend_registry::isregistered ("name")) {
  Echo Object Registry name is already defined;
} else{
  echo "Object registry name is not defined";
}
echo "<p>";
if (zend_registry::isregistered ("Age")) {
  Echo Object Registry age is already defined;
} else{
  echo "Object Registry age is not defined";
}
Zend_registry::_unsetinstance ("name");
echo "<p>";
echo "After the operation:";
echo "<p>";
if (zend_registry::isregistered ("name")) {
  Echo Object Registry name is already defined;
} else{
  echo "Object registry name is not defined";
}
echo "<p>";
if (zend_registry::isregistered ("Age")) {
  Echo Object Registry age is already defined;
} else{
  echo "Object Registry age is not defined";
}

Results:

Before performing an action: Object registry
name has been defined
Object Registry age is not defined
after performing an action: Object registry
name does not define
object Registry age not defined

Note: After the deletion method is completed, the registration information is not.

Summary:

This is the zend_registry of several commonly used methods and cases. The registry allows you to implement functions that many ordinary variables cannot implement.
