I'm proposing this change because it will remove duplicate functionality from the language. In PHP 4, "var" was the only way to declare a class member variable. PHP 5 introduced three new keywords for this purpose: public, protected, and private. "public" is functionally identical to "var". According to the docs: > Class properties must be defined as public, private, or protected. If > declared using var, the property will be defined as public. This is great for backwards compatibility from PHP 4, but it ultimately results in having two different keywords which do exactly the same thing. Does PHP 7 really need two keywords for declaring public class members? We're already removing PHP 4 style constructors in favor of the PHP 5 style ones, so why not also remove the PHP 4 "var" keyword in favor of the PHP 5 style keywords which explicitly state the visibility? For the small percentage of projects which still use "var", upgrading their code would be dead simple: just replace "var" with "public" everywhere you see it. I'm sure somebody can easily whip up a tool to automate that process. Because current usage of "var" seems low and the upgrade path is so simple, I don't think its a bad idea.
