Write a synonymizer script

Good afternoon! The services of a web programmer are required. It is necessary to write a script synonymizer of text using the phpMorfy library (knowledge of MyStem, Porter stemmer is welcome) with further preparation of the text for randomization.
The main point is that in the text when you click on a word, a drop-down list appears, from which words are selected, which are substituted instead of the original and framed into specified tags.
Detailed description of the technical task in personal correspondence.
