A PHP JSON parser and validator with detailed error messages and configurable parsing options.
JSON Lint for PHP is a JSON parsing and validation library that provides detailed, human-readable error messages when JSON parsing fails. It solves the problem of PHP's native `json_decode()` returning generic errors by offering precise diagnostics with line numbers and context.
PHP developers who need robust JSON validation with clear error reporting, particularly those building APIs, data processing pipelines, or tools that handle user-provided JSON.
Developers choose this library because it offers superior error diagnostics compared to native PHP functions, configurable parsing options for edge cases like duplicate keys and comments, and seamless integration as a fallback validator alongside `json_decode()`.

Provides human-readable error messages with line numbers and context, unlike json_decode's generic errors, making debugging malformed JSON much easier.
Supports configurable handling of duplicate keys, allows comments in JSON, and can parse to associative arrays, offering more control than native functions.
Designed to complement json_decode by providing detailed errors only when parsing fails, as shown in the Composer integration example for efficient validation.
Can be installed via Composer and used as a command-line utility to lint JSON files directly, adding versatility beyond library usage.
Explicitly slower than PHP's native json_decode, as noted in the README, making it unsuitable for high-throughput or performance-sensitive scenarios.
Requires handling exceptions and configuring flags for advanced features, adding overhead compared to simple json_decode calls and error checks.
While it allows comments, it doesn't support full JSON5 or other non-standard JSON formats, which might require additional libraries or custom work.
