Getting a variable from an object with a string in PHP

Question

I have a Persons object. It has a variable name accessible by saying

$p = new Person('John');
echo $p->name;

Now I have a string.

$name = 'name';

I need to get $p->name using $p and $name. Something like

echo $p->[$name];

Wow. That's easy. Why would the {} be necessary? I mean in what case would they be?

If you want to go all out with something like $p->{functionA(functionB().$name)} but it's a bit excessive ;) I also find it easier to read. $p->$name looks too much like $p-$name.

echo $p->$name; may generates error if it contains special characters so following one is perfect

echo $p->{$name};
