When backend automation systems fail to release lock files, critical operations grind to a halt. Learn how we debugged a complex interaction between PHP 8.1 mysqli exceptions, CodeIgniter 4’s global error handler, and bypassed finally blocks to restore stability in a high-scale enterprise SaaS platform.

Upgrading legacy applications to PHP 8 introduces strict type enforcement challenges. During a recent logistics ERP modernization, our engineering team encountered critical TypeError crashes in CodeIgniter 3’s ODBC driver. Discover how we diagnosed and resolved the affected_rows() issue to ensure stable database operations without rewriting the data access layer.
