Informations about the package feature-flags
ez-php/feature-flags
Simple feature flag evaluation for the ez-php framework. No external service required — flags are stored in a PHP file, a database table, or a plain array.
Installation
Register the provider in provider/modules.php:
Usage
Configuration
Add a config/flags.php to your application:
Drivers
| Driver | Config key value | Description |
|---|---|---|
file |
file |
Reads a PHP file returning array<string, bool> |
database |
database |
Reads a feature_flags table via PDO |
array |
array |
Empty in-memory driver (CI / test environments) |
File driver
Create config/flags.php in your application:
Database driver
Create the feature_flags table (example migration):
For per-context overrides (e.g. per-user beta rollouts), also create feature_flag_contexts:
When enabledFor('flag', $userId) is called, the driver checks feature_flag_contexts first; if no matching row exists, it falls back to the global feature_flags value. A missing feature_flag_contexts table is silently treated as "no overrides" — no migration is required for basic use.
Insert flags directly via SQL or through your own admin interface:
Behaviour
- Unknown flags default to
false—Flag::enabled('unknown')never throws. - Drivers never throw — all query/file failures are caught internally and result in
false. - The
Flagfacade throwsRuntimeExceptionwhen called beforeFeatureFlagServiceProviderhas been booted — this is a programmer error, not a runtime failure.
Testing
All tests run without external infrastructure (SQLite :memory: for the database driver, temp files for the file driver).
