accessing member variable in class

[programming.name]

Hi,

Please consider the following code:

<?php
class a
{
     public function f()
     {
          $name = 'John';
     }
}

$name = new a()

echo $name->f()->$name;

 

By doing this, I thought I could echo the name John, but it displays nothing. Where did I make a mistake?

 

Thanks

Firstly, you would need to make $name a public property. Secondly, your f() method would need to return an instance of itself in order to be chainable.

 

<?php
class a
{
    public $name;

    public function f()
    {
        $this->name = 'John';
        return $this;
    }
}

$name = new a;
echo $name->f()->name;

Maybe it's just me, but using chaining in this way smells.

It sure does, besides I believe the OP actually isn't aware of __set($key, $value), __get($key), __isset($key), and __unset($key) or ArrayAccess.

Seems like he's just starting. Give him time
