Log
This project is a standardized specification for logging APIs in PHP. It defines a common logging interface and a set of severity levels to ensure ecosystem-wide compatibility between different logging implementations.
The project focuses on PHP library interoperability by providing a vendor-neutral interface. This allows various software packages to record application events consistently without being tied to a specific logging vendor, adhering to the PSR-3 implementation standard.
The specification covers architectural primitives for logging abstractions, including implementation-agnostic designs and standardized method signatures. It enables context-aware message passing and fixed-level severity mapping to maintain consistent importance ranking across different libraries.
Features
- PHP Standard Interface Implementations - Implements the PSR-3 standard interface to ensure logging compatibility across the PHP ecosystem.
- Interface-Based Abstractions - Implements interface-based abstractions to decouple logging calls from specific storage or transport implementations.
- Implementation-Agnostic APIs - Separates the logging API definition from the actual logic used to write logs to various targets.
- Interoperability Specifications - Provides an interoperability specification that allows various PHP packages to share a single logging implementation.
- Logging APIs - Provides a standardized API for recording application events through consistent method signatures and severity levels.
- Application Logging - Defines a common set of logging levels and interfaces for consistent application-level event recording.
- Log Level Mappings - Defines standardized log level mappings to ensure consistent importance ranking across different PHP logging libraries.
- Logging Interfaces - Establishes a common set of logging interfaces and levels to ensure interoperability between PHP implementations.
- API Signature Standards - Enforces specific argument types and return values for logging methods to guarantee interchangeable library compatibility.
- Structured Logging - Provides a mechanism for passing associative arrays as context alongside log messages for structured logging.
