What's the difference between 2 classes?

[programming.name]

Hi,

 

There are two classes; a and b.

 

class a

{

private $a;

public function method_a($_a)

{

return $a = $_a;

}

}

$var = new a();

echo $var->method_a("Some value");

 

class b

{

private $b;

public function method_b($_b)

{

return $this->b = $_b; }

}

$var = new b();

echo $var->method_b("Some value");

 

What is the real difference between two classes?

 

Thanks

Nothing really, there both incorrectly returning a bool.

he uses = that doesn't return a bool rather the assigned value (in this case a string). See, VB is bad for your health.

In the second you assign the value to an internal class variable. Both return your input "Some value".

Oh, indeed it does. I would have assumed it would have returned a bool based on whether or not the assignment worked or not.
