Alr raised as issue

I have the same failure error. There must be some issues at PHP language tests.
I will try to translate my code to another language and see what will happen.

Have exactly same problem (php).
1, 3, 4, 7, 9, 10, 13, 15, 19, 22 - 1st test, expected 22
1, 3, 4, 7, 9, 10, 13, 15, 19, 21, 22, 27, 28, 31, 39, 40, 43, 46, 58, 64 - 2nd test, expected 67 and at attempt expected 57 (with same n=20)!?!?

My implementation passed:

public function test30() { $this->assertEquals("Lorem ipsum dolor sit amet,\nconsectetur adipiscing elit.\nVestibulum sagittis dolor\nmauris, at elementum ligula\ntempor eget. In quis rhoncus\nnunc, at aliquet orci. Fusce\nat dolor sit amet felis\nsuscipit tristique. Nam a\nimperdiet tellus. Nulla eu\nvestibulum urna.

From insruction tab and passed base test.
Fails "Testing for width=15" with :"Line length is not equal
Failed asserting that 10 matches expected 15."
But i get source string and make conversion mannualy by rules from instructions tab and result with my implementation is same.

And there are no info about what exact no right, but seems in other languages there are expected length at least.
So i think there are invalid tests for php langauge.

Empty string.

it says "should work with empty array" what is the input of that test case then?
