PHP Error Handling

Priority: P0 (CRITICAL)

Structure

src/
└── Exceptions/
    ├── {Domain}Exception.php
    └── Handler.php

Implementation Guidelines

Exception-Driven: Favor throwing exceptions over returning false or null for error states.
Throwable Interface: Always catch Throwable for both PHP 7/8 Errors and Exceptions.
Custom Exceptions: Extend RuntimeException or LogicException for domain-specific errors.
Multi-Catch: Use Union types in catch blocks: catch (DomainException | InvalidArgumentException $e).
Global Handler: Use set_exception_handler and set_error_handler for top-level logging and cleanup.
Finally: Always use finally for resource cleanup (e.g., closing file handles, DB connections).
PSR-3 Logging: Implement Psr\Log\LoggerInterface for structured error reporting.
Production Guard: Ensure display_errors=Off and log_errors=On in production php.ini.

Anti-Patterns

No @ error suppression: Handle or log errors explicitly.
No empty catch blocks: Log or rethrow all caught exceptions.
No exceptions for control flow: Reserve for unexpected errors only.
No display_errors in production: Log to file; never show users.
