# [RFC] [Discussion] Minimum supported versions for PHP 8.6

**[externals.io](https://daily.dev/sources/externals)** · 5 min read · 0 upvotes · 0 comments

## Summary

A PHP internals RFC discussion proposes minimum supported version requirements for PHP 8.6, specifically requiring autoconf when building from source, and MySQL 5.7.3 or MariaDB 10.2.4 for persistent database connections. The RFC introduces COM_RESET_CONNECTION support to PDO and mysqlnd, which makes persistent connection behavior more predictable. Discussion touches on ecosystem impact: users on older MySQL/MariaDB versions using PDO::ATTR_PERSISTENT may face breaking changes or silent fallback to non-persistent connections when upgrading to PHP 8.6.
