I can't rebuild documentation for PHP 7.1. I haven't enough knowledge to do this. This
documentation was available as tar.gz, one html, many html, zip files to download. I thought, that
there are some archive with older documentation. Thank You very much for help, Your assistance.

There is no readily downloadable or viewable documentation for PHP
7 only. However, you can checkout an older revision of the doc
repo[1], and build the documentation yourself[2].

I understand. I'm preparing for Zend Certified PHP Engineer exam, which bases on PHP 7.1. It is
possible to read or download old documentation for this version? Thank You very much in advance.

This argument is no longer optional as of PHP 8.0.0[1].

Let's look at crypt function:
crypt ( string $string , string $salt ) : string # current documentation
and look at previous documentation:
crypt ( string $str [, string $salt ] ) : string # in this case we know that second argument is
optional. In current version we don't know.

Actually, this case is not related to the mentioned PR, but rather
because variable-length argument lists[1] can be empty.
