Question

I have a PHP Object with an attribute having a dollar ($) sign in it.

How do I access the content of this attribute ?

Example :

echo $object->variable; // Ok

echo $object->variable$WithDollar; // Syntax error :-(

Answer 1

1. With variable variables:

   $myVar = 'variable$WithDollar';
   echo $object->$myVar;
   

2. With curly brackets:

   echo $object->{'variable$WithDollar'};
