/* Describe a user's class, 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;
}
}
/* instantiation, and when creating this user, is very painful, need to set user name, age and Money */
$peopleInfo = Array (
' UserName ' = ' initphp ',
' Userage ' = 28,
' Usermoney ' = ' 100 Yuan '
);
$UserInfo = new UserInfo;
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.
