There is a doubt that I find interesting and would like to post here.
How do you usually use methods whose functionality is to set and retrieve attributes in a class ?
They use this way:
public function setNome($nome)
Or with magic methods? So:
public function __set($attr,$valor)
I ask this for the fact of seeing in other codes, despite having many magic methods do not use.
Nothing prevents you from using both forms, this can even be of great value. When I use PHP , I use get/set and the name of the fields, like this:
<?php
class Cliente {
private $id;
private $nome;
public function __construct($id = 0, $nome = NULL){
$this->id = $id;
$this->nome = $nome;
}
public function getId(){
return $this->id;
}
public function getNome(){
return $this->nome;
}
public function setId($value){
$this->id = $value;
}
public function setNome($value){
$this->nome = $value;
}
public function __set ($name,$value){
$this->$name = $value;
}
public function __get ($name){
return $this->$name;
}
}
$cliente = new Cliente();
$cliente->id = 1;
$cliente->nome = "Fulano 1";
echo $cliente->getId() . " " . $cliente->getNome();
Notice that the private $id and private $nome are being set with magic methods and in getId() and getNome() I'm taking values, that is, they can work together to allow this type of implementation.
Example: Ideone
> Another important factor is that you can work with this code of set in the default Fluent in this way;
<?php
class Cliente {
private $id;
private $nome;
public function __construct($id = 0, $nome = NULL){
$this->id = $id;
$this->nome = $nome;
}
public function getId(){
return $this->id;
}
public function getNome(){
return $this->nome;
}
public function setId($value){
$this->id = $value;
return $this;
}
public function setNome($value){
$this->nome = $value;
return $this;
}
public function __set ($name,$value){
$this->$name = $value;
}
public function __get ($name){
return $this->$name;
}
}
$cliente = new Cliente();
$cliente->setId(2)
->setNome("Fulano 2");
echo $cliente->id . " " . $cliente->nome;
Example Ideone
> Shortly after being called the setId method, you call setNome (successively if you have more methods Fluent ), which is the logic of this pattern. So there is a flexibility that magic methods do not provide, but public% methods can have it.
As reported, nothing prevents you from working together on PHP. They are magical methods:
