PHP Design Pattern Series - Builder Pattern_PHP Tutorial

What is Builder Mode
The builder pattern is mainly to eliminate the complex creation process of other objects.
Design scene
There is a user's UserInfo class. To create this class, you need to create the user's name, age, money and other information to obtain the user's specific information results.
Create a UserInfoBuilder user builder class. This class encapsulates the complex operations of creating UserInfo such as name, age, money, etc., simplifying the creation process of user classes

//Builder pattern, the purpose is to eliminate the complex creation process of other objects

/* Class that describes a user, including user name, age, money */
class UserInfo {

protected $userName = '';
protected $userAge = '';
protected $userMoney = '';

Public function setUserName($userName) {
$this->userName = $userName;
}  
       
Public function setUserAge($userAge) {
$this->userAge = $userAge;
}  
       
Public function setUserMoney($userMoney) {
$this->userMoney = $userMoney;
}  
       
Public function getPeople() {
echo "This person's name is: " . $this->setUserName . ', Age is: ' . $this->userAge . ', Money: ' . $this->userMoney;
}  
}
/* It is very painful to instantiate and create this user. You need to set the user name, age and money*/
$peopleInfo = array(
'userName' => 'initphp',
'userAge' => 28,
'userMoney' => '100 yuan'
);
$UserInfo = new UserInfo;
//You need to set the user information step by step below to get the user details. The process is tangled and painful
$UserInfo->setUserName($peopleInfo['userName']);
$UserInfo->setUserAge($peopleInfo['userAge']);
$UserInfo->setUserMoney($peopleInfo['userMoney']);
$UserInfo->getPeople();
Code: UserInfoBuilder User information builder class, which encapsulates the creation process of UserInfo, making developers feel comfortable when using it
[php]
//Builder pattern, the purpose is to eliminate the complex creation process of other objects
include("UserInfo.php");
class UserInfoBuilder {
protected $obj;
       
Public function __construct() {
$this->obj = new UserInfo;
}  
       
Public function buildPeople($peopleInfo) {
            $this->obj->setUserName($peopleInfo['userName']);
           $this->obj->setUserAge($peopleInfo['userAge']);
           $this->obj->setUserMoney($peopleInfo['userMoney']);
}  
       
Public function getPeople() {
$this->obj->getPeople();
}  
}

/* The creation process is encapsulated, making it easy for users to use */
$peopleInfo = array(
'userName' => 'initphp',
'userAge' => 28,
'userMoney' => '100 yuan'
);
$UserInfoBuilder = new UserInfoBuilder;
$UserInfoBuilder->buildPeople($peopleInfo); //Directly build
$UserInfoBuilder->getPeople();
