I'm looking at the source of a web sockets server and I see these various forms: "ws://{$host}{$path}" "HTTP/1.1 ${status}\r\n" Are these simply equivalent to: "ws://" . $host . $path "HTTP/1.1 " . $status . "\r\n"; and if so, is there any particular benefit to using that form? Or if not, what do they mean? (I've read up about variable variables).

If you want to embed $array[CONSTANT], then the {} is used. I use {} out of habit for non arrays. Not sure if there is an impact.

The braces are also used when the characters following the variable are also valid variable name characters :) Cheers, Rob. -- E-Mail Disclaimer: Information contained in this message and any attached documents is considered confidential and legally protected.
