Hi all,

I've wasted two days trying to find this in the documentation. Google
is no help here either; they only index text.

While looking at some code using objects I came across this:

$this->{$spec}

The example works with or without the curly braces, but I know they
aren't there for just for decoration ;)

Will somebody be so kind as to point me where in the docs this syntax is
explained?

tia

It's documented here:
http://php.net/manual/en/language.variables.variable.php

It works for function and class names as well.

The style used above is superfluous since no additional operations are
being done within the braces and so the braces are redundant. This is
why it works either way.

Cheers,
Rob.
