Returns wrong sentiment for PHP 7

[sameerpanjwani]

This package used to work up well till we had PHP 5.6 but after we upgraded to PHP 7, phrases that were "neutral" are being returned as "positive". Not sure why?

All possible neutral phrases like:
"sample test line"
"maths in science"
"men and women in a line"

Any ideas
