Unique Violation Detector Laravel Package

mpyw/unique-violation-detector is a tiny PHP utility that tells you whether a database exception was caused by a unique constraint violation. Instead of scattering driver-specific error-code checks throughout your code, you hand it a caught exception and get a simple boolean answer.

It normalizes the quirks of MySQL, PostgreSQL, and SQLite error responses, so the same logic works across drivers and in both raw PDO and Laravel applications.

• Driver-agnostic detection of duplicate-key errors
• Works with PDO and Laravel query exceptions
• No configuration or service provider required
• Ideal for safe "insert or ignore" and retry logic
• Zero dependencies, framework-light footprint
