Operating system: 
PHP version:      Irrelevant
Package:          Documentation problem
Bug Type:         Documentation Problem
Bug description:function parameter ?t $v not described

Description:
------------
---
From manual page: https://php.net/functions.arguments
---
The manual page says no single word about function parameters declared
as

   ?<type> $<param-name>

where <type> is the data type of the parameter 
and <param-name> is the name of the parameter.

What is the meaning of such a parameter declaration?
