Is there a lemmatizer for PHP?

Does anyone know of a lemmatizer in PHP? Or, at worst, some way to use a
lemmatizer in another language (python NLTK, for instance?) in a PHP
webapp?
I'm building a macro-etymological analyzer and I've encountered this issue
where the etymological database doesn't contain conjugated words. A
lemmatizer would correct this, I think, by giving me the word "say" when
the dictionary can't find "said," and returning "good" when the dictionary
can't find "better," etc.
