Note that in C# the new "init" keyword is explicitly an extension of property accessors [1], and relates specifically to "object initializers", which PHP does not have; a proposal for them last year [2] was rejected. An existing "readonly" keyword [3] allows you to write a variable only in the constructor, and "init" is mostly needed because object initializers are run too late for this. C# 9.0 also has a bunch of features around immutable data structures in general, including a variant of object initializers called "with-expressions" [4] to solve the "modified clone" problem.
