Why not like C#?

[Description("My Function")]
function my_function()
{}

Without the semicolon, this wouldn't be valid in any other context.

You may try to replace attribute syntax with @attr(...) (without semicolon)
into our PHP parser.
Note that we have LALR grammar + restrictions caused by semantic actions.
If you are able to do this, I'll add it into the RFC as an option.
