Vasiliy Krivoplyas
Vasiliy Krivoplyas's work was selected for the XERJ Corpus Hub, the open reference memory AI coding agents search before they write code. When an agent meets the same problem, it gets this implementation back as a worked example, with the author and the repository attached.
Totals across every corpus @tommyknocker appears in; a commit selected for two corpora counts once. Files and lines count the selected commits; each corpus indexes the whole repository at its pinned commit.
What an agent can do with the pdo-database-class corpus
tommyknocker/pdo-database-class: Framework-agnostic PHP database library with unified API for MySQL, MariaDB, PostgreSQL, SQLite, MSSQL, and Oracle. Query Builder, caching,
- Look up how pdo-database-class implements database-abstraction-layer, mysql, postgresql, with answers cited to file and line.
- Reuse a worked example: the commit “improve query reliability and PHP 8.5 support” (86 files · PHP).
- Answer from pdo-database-class's real PHP source instead of memory (Databases and storage engines).
- Where does pdo-database-class handle “improve query reliability and PHP 8.5 support”?
- How does pdo-database-class implement database-abstraction-layer?
- What does tests do in pdo-database-class?
