private $attribute is not used anywhere. I try to pass one parameter the first function get, past two parameters the function set but it is not working what is the differents between get and set
I have this two but doesn't works
$a->attribute("albert",38);
$a->attribure = 5;

class classname {
    private $attribute;

    function __get($name){
        return $this->$name;
    }
    function __set($name,$value){
        $this->$name = $value;
    }
}
$a = new classname();
/*$a->__get("albert");
$a->__set("albert",38);
$a->attribute("albert",38);*/
$a->attribure = 5;

    You don't actually call the __set() or __get() directly. Rather, they are used if you try to access a class property that is not public. So if you try to access $a->attribute, PHP will internally call the __get() or __set() as applicable. I've historically used only the __get(), so that I could make a property effectively read-only. After all, if you want to allow internal code to both read and set a property, why not just declare it as public?

    Also, as of PHP 8.1, you can now declare a class property as public readonly, getting rid of the need to use __get() for it in those cases. (See https://www.php.net/manual/en/language.oop5.properties.php#language.oop5.properties.readonly-properties)

      For a start, you've written attribure, not attribute. When you evaluate $a->attribure = 5;, __set gets called with a name of attribure and a value of 5, and tries to set $this->attribure to 5. And the class doesn't have an attribute named attribure. Starting in PHP 8.2 you'd get a deprecation notice about this, but either way your $a object now has a new property named attribure with a value of 5.

      class classname {
    private $attribute;

    function __get($name){
        return $this->$name;
    }
    function __set($name,$value){
        $this->$name = $value;
    }
}
$a = new classname();
/*$a->__get("albert");
//$a->__set("albert",38);
//$a->attribute("albert",38);*/
$a->attribure = 5;

echo $a->attribure;

      I pass only one parametr to __set and they are two parameters $name,$value and with __get I pass any parameter to $name.
      I don't understand $a->attribute = 5, I suppose I pass the parameter to private $attribute

      You don't have $a->attribute = 5. If you look at the code you've actually written you have $a->attribure = 5.
      If it did say $a->attribute = 5; then things would happen. The attribute named $attribute is marked private so it's not visible outside the class. So when you try to set it, the attribute isn't found. When that happens, __set is run instead and, because it is inside the class, it can see the attribute to set it.

      Like NogDog said, this is generally better handled by using readonly. __set is better for creating virtual attributes that aren't stored explicitly but recalculated each time, or for adding extra consistency checks on what is being stored.
