Class variable interpolation

[August Karlstrom]

Hi,

Does anyone know the correct syntax to interpolate a class variable, $x
say, inside a string? I tried

"{self::$x}"

but it produces the string

{self::x}

Here it will produce '{self::}', and a notice $x isn't set.
AFAIK, with static variables, one has the same 'problem' as with
constants: no interpolation possible, just use temporary variables or
concatenation.

If that is the case it was probably overlooked by the language
developers. I see no reason why static variables could not be
interpolated with the syntax above.

Right, but it is kind of clumsy.

Using sprintf() and its ilk is also viable, and, IMO, can be easier on
the eyes than relying on variable interpolation, anyway.

For shorter strings, yes, but probably not with 50 lines of HTML in a
heredoc.

A heredoc is your case for code legibility? :^)
