Do you mean

echo "${array[$key]}"; // Works

should be errror?
This form is common in shell scripting.

http://tldp.org/LDP/abs/html/parameter-substitution.html

I'm using it regularly. I guess many users expect following forms to work.

 $obj->${array[$key]}; // Syntax error
 $obj->${key}; // E_NOTICE. Does not work

What others expect?

Regards,
