References in PHP

The use of references in PHP is still relatively good, you can avoid some of the return values or the processing of the values that need to be modified

Like what:

$users = Array (

Array ("name" = "KIVMI", "Age" =>20, "sex" = "male", "attribute" and "single"),

Array ("Name" = "Girl", "Age" =>18, "sex" = "female", "attribute" = "single")

);

Class combine{

Private $users;

Public function __construct ($users) {

$this->users = $users;

}

Public Function changeattr () {

foreach ($this->users as & $user) {

$user [' attribute '] = "married";

}

return $this;

}

Public Function getusers () {

return $this->users;

}

}

$COM = new Combine ($users);

$COM->changeattr ()->getusers ();

You will magically discover that the current user's attribute is no longer a single, but a married. Isn't that funny?
