PHP，__ get（）方法和数组参数

Question

I want to achieve this effect:

class Foo {
   public $bar; // array('aaa' => array('bbb' => 'ccc'))
   public function __get($value)
   {
      return $this->bar[...][key($value)]; // don't know what to implement here
   }
}

$obj = new Foo();
$obj->aaa['bbb']; // should return 'ccc'

Is this possible? How can I do this?

How can I get to the 'ccc' value from the Foo::$bar array from the inside of the __get() method if I want to call it this way?

Answer 1

Try this:

<?php
class Foo {
    public $bar = array('aaa' => array('bbb' => 'ccc'));
    public function __get($value) {
        return $this->bar[$value];
    }
}

$obj = new Foo();
echo $obj->aaa['bbb'];

will return:

ccc

Answer 2

class Foo {
   public $bar = array('aaa' => array('bbb' => 'ccc'));
   public function __get($value)
   {
      return $this->bar[$value];
   }
}

$obj = new Foo();
var_dump($obj->aaa['bbb']);

Got what you wanted after your edit.

Answer 3

<?php

class Foo 
{
    // note you had: array('aaa' => array('bbb', 'ccc'));
    // so `bbb` and `ccc` were values, not keys.
    public $bar = array('aaa' => array('bbb' => 'ccc'));

    public function __get($name)
    {
        return $this->bar[$name];
    }
}

$obj = new Foo();
echo $obj->aaa['bbb']; // should return 'ccc'

// output: ccc

Answer 4

Not sure from how you phrased the question, but I think this might be what you're looking for?

<? 
class Foo {
    function __construct(){
        $bar = array(
            'aaa' => array('bbb' => 'ccc'),
            'zzz' => array('yyy' => 'xxx'),
        );
        foreach($bar as $key => $value){
            $this->{$key} = $value;
        }
    }
    public function __get($value){
        // return $this->bar[...][key($value)]; // don't know what to implement here
    }
}

$obj = new Foo();
echo $obj->aaa['bbb']; // ccc
echo $obj->zzz['yyy']; // xxx
