What does $rectorConfig->phpVersion(); do?

Hi,

i read the readme but this still confuses me. Say my computer is on PHP 8.1 and i have an open source project that support minimum PHP 7.3

in my rector.php file

do i define 7.3 or do i define 8.1?

$rectorConfig->phpVersion(PhpVersion::PHP_73);

or

$rectorConfig->phpVersion(PhpVersion::PHP_81);

You should use symbolic links.
By doing so, you can manage the development version separately from other working directories.

Hi,

this set PHP version syntax level for the Rector rules. E.g. if you set:

$rectorConfig->phpVersion(PhpVersion::PHP_74);

If there is a rule that completes type to a property, it will use the PHP 7.4 typed property:

-private $name;
+private string $name;

But if you set PHP 7.3:

$rectorConfig->phpVersion(PhpVersion::PHP_73);

Nothing will be changed there :)

Usually this version is resolved based on your composer.json, where the lowest PHP version supported is defined.
