How should my rector.php look like in a php 7.3 project?

[ziming]

Currently if we look at the generated rector.php template, it seem to use language features above php 7.3

https://github.com/rectorphp/rector/blob/main/templates/rector.php.dist

Other than removing the void keyword, how should i modify it so that the rector.php file is PHP 7.3 valid? and still work?

it uses language features above php 7.3

What exact features do you mean? The void is available since PHP 7.1. https://www.php.net/manual/en/migration71.new-features.php

What error do you get when you run Rector with this config?

my bad, i saw the github action error message wrongly.

but just curious, this is valid in php 7.3?

return static function ...

What is the result you get from your PHP version when you run it?

[samsonasik]

static function exists since PHP 5.4 https://3v4l.org/MAeXLi#v5.4.45

thanks for the site. as I said earlier I see wrongly from github action.

nice to know I can just write return outside of any class or function in a file.
