PHP access object member as if array member

Question

Is it possible to access to object member as if array member?

for example

echo $a->b;

to

echo $a[b];

Would it be any php ini settings, or this is quite impossible in PHP?

Answer 1

I tried for a one-liner but:

$x = (array)$a;
echo $x['b'];

Or of course to convert the object: $a = (array)$a;

Answer 2

extends ArrayObject or implements ArrayAccess so you can access the object as array.
