It appears SMOG is broken. Can anyone confirm this?
Yes. There seem to be many issues here.
public $normalise = false;

//$strText = utf8_decode($strText);
$strText = preg_replace('/([^\.\s]*[0-9][^\.\s]*)/', '', $strText); // Remove words with numbers
$strText = preg_replace('/\'/', '', $strText); // Remove ' symbol, dunno if helps.
$strText = preg_replace('` `', ' ', $strText); // Remove double spaces (because for some reason you calculate words based on number of spaces)
Now, I don't have an account on readability-score.com, but I tried with other online calculators:

SMOG | 16.96 | 23.2 | 16.4 | 9.4 | 17.7 |
I also tried with my own test text, which is a bit longer.

SMOG | 12.8 | 17.7 | 12.1 | 10.7 | 13.6 |
But, yeah, there still seem to be problems. For example now the Coleman-Liau index went up compared to the other calculators.
Hi,
Text: "June 23rd, 2015 How Cigna deal limits Anthem’s Blue Cross brand “When health plans operate using the Blue Cross and Blue Shield brand, they are generally limited to business in a specific state or region as part of a licensing agreement with their trade group, the Blue Cross and Blue Shield Association. So when Anthem (ANTM), a major operator of Blue Cross plans, made its $184-a-share offer for Cigna (CI) to grow both health insurance businesses, it created potential hurdles when it comes to Anthem’s valuable Blue Cross brands expanding."
On readability-score.com I'm getting value of 15.2 for SMOG, but with $textStatistics->smogIndex($input) only 9.4. This is big difference. Am I doing something wrong?
