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. -- http://www.interjinn.com Application and Templating Framework for PHP
