How to get a Var only output in a php code CF8

Question

Hello

I used to use custom code in SF6 and get a var-only output. But I don't know how to get a var-only output in PHP code in CF8. The result of the PHP code is displayed onscreen.

Is there a way out?

Thanks

Ron

do not use "echo", just return whatever value in your PHP code and use {var:php_name} or $this->get("php_name") in another PHP code
