Details

Note that some pages describe connectors not officially supported by the Tarantool team:

• https://www.tarantool.io/en/doc/latest/how-to/getting_started_php

Such topics can be dropped from docs. If necessary, a reader can find them in the 2.11 help.

Consider creating a new connectors directory inside https://github.com/tarantool/doc/tree/latest/doc/code_snippets/snippets. This directory might contain a single-instance application with sample data and a user with specific privileges used for remote connections (not guest with the super role!). Related PR: #4054.
