When using CodeIgniter to manage database backups, what steps should be taken to verify that a backup file can be restored correctly and that the restored data matches the original source? Consider checking file integrity, running a test restore on a staging database, comparing row counts or checksums, and handling potential version mismatches. What built‑in
CodeIgniter 4 utilizes a driver-based caching system relying on Time-To-Live (TTL) for data expiration. While the framework supports various backends such as Redis, Memcached, and File, it lacks a native mechanism for tag-based invalidation or group cache clearing. When underlying database records are updated, the associated cache entries remain stale until
CodeIgniter 4 enables database-agnostic query construction through its Query Builder, allowing developers to run integration tests using an SQLite in-memory database via the DatabaseTrait . This approach facilitates testing CRUD logic without requiring production credentials or a live database server. The challenge arises when the application relies on datab
CodeIgniter's Database Query Builder provides limit() and offset() methods to abstract result constraints across different database drivers. This functionality is frequently used in conjunction with the Pagination class to manage large record sets by calculating the starting index and page size. While these methods ensure cross-database compatibility, the un
