PHP design Pattern Series-builder mode

• What is Builder mode

The builder pattern is primarily designed to eliminate the complexity of other object creation processes.

• Design Scenarios

1. There is a user's UserInfo class, create this class, need to create user's name, age, money and other information in order to obtain the user specific information results.
2. Create a Userinfobuilder user builder class that encapsulates the UserInfo complex creation of names, ages, and money to simplify the creation of user classes

• Code: UserInfo class, creating a UserInfo class is complex and painful.

    //Builder mode, designed to eliminate the complexity of other object creation processes          /*describe a user's class, including the user's name, age, and money*/      classUserInfo {protected $userName= ' '; protected $userAge= ' '; protected $userMoney= ' ';  Public functionSetusername ($userName) {              $this->username =$userName; }                        Public functionSetuserage ($userAge) {              $this->userage =$userAge; }                        Public functionSetusermoney ($userMoney) {              $this->usermoney =$userMoney; }                     Public functiongetPeople () {Echo"The name of this person is:".$this->setusername. ', Age is: '.$this->userage. ', Money: '.$this-Usermoney; }      }      /*instantiation, and when creating this user, is very painful, need to set user name, age and Money*/      $peopleInfo=Array(          ' UserName ' = ' initphp ', ' userage ', ' usermoney ' = ' 100 '          ); $UserInfo=NewUserInfo; //below need step by step set user information, can get user details, process tangled and painful    $UserInfo->setusername ($peopleInfo[' UserName ']); $UserInfo->setuserage ($peopleInfo[' Userage ']); $UserInfo->setusermoney ($peopleInfo[' Usermoney ']); $UserInfo->getpeople ();

Code: Userinfobuilder User Information Builder class that encapsulates the UserInfo creation process and is comfortable for developers to use.

<?PHP//Builder mode, designed to eliminate the complexity of other object creation processes    include("userinfo.php"); classUserinfobuilder {protected $obj;  Public function__construct () {$this->obj =NewUserInfo; }                     Public functionBuildpeople ($peopleInfo) {              $this->obj->setusername ($peopleInfo[' UserName ']); $this->obj->setuserage ($peopleInfo[' Userage ']); $this->obj->setusermoney ($peopleInfo[' Usermoney ']); }                      Public functiongetPeople () {$this->obj->getPeople (); }      }            /*The creation process is encapsulated and the user is simple to use*/      $peopleInfo=Array(          ' UserName ' = ' initphp ', ' userage ', ' usermoney ' = ' 100 '          ); $UserInfoBuilder=NewUserinfobuilder; $UserInfoBuilder->buildpeople ($peopleInfo);//Direct a Build    $UserInfoBuilder->getpeople ();
