Goodnight! I am very new in this (Stardog). There is any way use stardog with php? Thank you very much. Greetings from Argentina!
Welcome, there aren’t any PHP libraries specifically for Stardog that I’m aware of but Stardog supports standard SPARQL and has a Rest API https://stardog.docs.apiary.io/ that you should be able to use. I haven’t really worked with PHP so I’m not sure how up to date these are but you might want to look at http://www.easyrdf.org/
And even more Graphite, a PHP Linked Data Library http://graphite.ecs.soton.ac.uk/ from the same author.
