How to access object property when property name contains - (hyphen)

Question

I need an escape sequence for - or the minus sign for php. The object has a name-value pair where the name happens to be having - between 2 words.

I can't do this using \ the standard escape sequence (- isn't anyways documented).

I can store the name in a $myvariable which can be used but out of curiosity is it possible to do the following?

$myobject->myweird-name

This gives an Error because of -

Answer 1

This is what you need:

$myobject->{'myweird-name'};
