Above example is a classic one where readability and maintainability deal well together. First of all everything works as expected but obviously you need to know what you need. It is ambiguous to write $$arr[3] ... what do you expect? Did you mean the variable derived by $arr[3]? echo "This works: {$$arr[3]}"; since curly brackets make the meaning of the expression explicit, it will be 3 indeed. What is the less ambiguous, readable, easy to maintain, way to obtain that result? echo "This works: {${$arr[3]}}"; If our aim is to get the variable with name equal to the value of $arr[3] Can you see now why I am talking about good practice? Zero ambiguity, and that's how I like to code Regards _________________________________________________________________ Windows Live: Friends get your Flickr, Yelp, and Digg updates when they e-mail you. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_3:092010
