Hi there, I am not a core PHP language developer, just a regular PHP programmer, and cannot speak for the whole community, so I'll just share my opinion.
I believe a new language feature suggestion should contain not only its description, but also motivation: i.e. what are we trying to achieve with it. Will the development experience be worse without it, or maybe it disallows some sneaky bugs to appear in your code, or maybe it acts as a native documentation for your code etc. Personally it's hard for me to see what kind of improvement will restricting a type of a variable bring. It may prevent repurposing the variable with the same name for a different use somewhere down the function, which can lead to bugs if a function is large enough. However, for such cases I think better idea would be to introduce `const` variables like in JavaScript - which can only be set once and cannot be reassigned later. This way you'll also guarantee the type of the variable will be preserved. > We can add types in a lot of places, but we still don't have a way to add types to inline variables. > int $value = 10; > $value = 'foo'; // TypeError Can you describe some use cases where this feature will be useful? I see it's coming from statically typed / compiled languages like C++, but in such languages compiler must know variable type in order to manage memory properly. As PHP is an interpreted language, it doesn't have this problem. Regards, Illia / someniatko
