Is $options a reserved variable?

[Jonathan Lahijani]

The PageRender module provides you with an "options" variable that provides some useful information, such as filename, pageStack, etc.

Does that mean you should avoid redeclaring a variable of your own called $options?

No, you don't have to avoid using a variable called $options, because it $options is only used in a local scope, in this example it's used in the local scope of the method "renderPage()". It's not a global ProcessWire API variable like $page, $pages or $config, for example - you should avoid redeclaring these. Read more about these API variables here.

Yeah $options is a template var. If you need it you shouldn't overwrite it.
