Fixed.

The naming is kinda misleading. The $this->encode() call is my helper. But I've renamed the other var so it should be easier to read.

assertEquals(mixed $expected, mixed $actual[, string $message = ''])

Updated the translations (need approval), and added one for 7.0. Should be what you're asking for.

This is a copy-paste of the 7.4 code.

Fixed. Removed logging that was making it slower.

It's something that came to mind, but for some reason I expect people to be honest when doing these.

Will update them. Means I have to re-implement the methods in the tests to be able to test the returned values are correct, because I don't think a simple decoded !== encoded will suffice, although it might.

As I said in your review, the tests are the same as the original ones. An example or explanation would be useful.

PHP 7.0

PHP 7.4

Do tell when you've looked again. I guess you simply missed them.

Hmm. Aren't sample tests there for the user to check his implementation? :)

Actual tests have random strings and random rails number.

Look for testRandom() in test cases.

PHP Translation awaiting approval.

Really good kata.
