Exception

Framework base exception with JSON serialization support.

class Exception extends \Exception implements \JsonSerializable

Extends: Exception

Implements: JsonSerializable

Extends PHP's native exception to normalize default HTTP-style error codes, preserve context from chained exceptions, and expose a stable payload shape for API responses via JsonSerializable.

Properties

class

Class name captured from the previous exception, when available.

protected string $class

Type: string

trace

Standard stack trace.

protected array $trace

Type: array

Methods

__construct

Constructs a new exception instance.

public __construct(string $message, int $code = 500, ?\Throwable $previousException): void

The exception code doubles as the HTTP response status throughout the framework (see Hazaar\Controller\Error::setException), so it's constrained to the valid HTTP status range (100-599). Codes outside that range — e.g. a PDO SQLSTATE or driver error code passed through from a wrapped exception — are not valid HTTP statuses and would otherwise reach the response writer unchanged, which some SAPIs (e.g. FrankenPHP) treat as fatal rather than rejecting gracefully. Such codes are normalized to 500 and appended to the message so the original value isn't lost.

Parameters

Parameter	Type	Description
$message	string	the Exception message to throw
$code	int	the Exception code (defaults to 500 if not provided or outside the 100-599 HTTP status range)
$previousException	Throwable	the previous throwable used for exception chaining

jsonSerialize

Serializes the exception data to an array suitable for JSON encoding.

public jsonSerialize(): array

Returns: array

The returned array always includes:

• 'timestamp': The current Unix timestamp with microseconds.
• 'code': The exception code.
• 'message': The exception message.

If the 'display_errors' INI setting is enabled, the array also includes:

• 'file': The filename where the exception was thrown.
• 'line': The line number where the exception was thrown.
• 'class': The class name of the exception.
• 'trace': The stack trace as an array.

getClass

public getClass(): string

Returns: string

getStackTrace

Returns the stack trace as an array.

public getStackTrace(): array

Returns: array

If a previous exception was provided during construction, its stack trace is returned. Otherwise, the standard stack trace of this exception is returned.
