Class BaseErrorHandler

Base error handler that provides logic common to the CLI + web error/exception handlers.

  • bool

    Whether the config property has already been configured with defaults

  • $_defaultConfig protected
    array<string, mixed>

    Options to use for the Error handling.

  • $_handled protected
    bool
  • $logger protected
    Cake\Error\ErrorLoggerInterface|null

    Exception logger instance.

  • _logError() protected

    Log an error.

  • _stop() protected

    Stop the process.

    Returns the config for this specific key.

  • getLogger() public

    Get exception logger.

Parameters

int $code

Exit code.

Returns

void

configShallow() public

configShallow(array<string, mixed>|string $key, mixed|null $value = null): $this

Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.

Setting a specific value:

$this->configShallow('key', $value);

Setting a nested value:

$this->configShallow('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->configShallow(['one' => 'value', 'another' => 'value']);

Parameters

array<string, mixed>|string $key

The key to set, or a complete array of configs.

mixed|null $value optional

The value to set.

Returns

$this

getConfig() public

getConfig(string|null $key = null, mixed $default = null): mixed

Returns the config.

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

$this->getConfig('some.nested.key');

Reading with default value:

$this->getConfig('some-key', 'default-value');

Parameters

string|null $key optional

The key to get or null for the whole config.

mixed $default optional

The return value when the key does not exist.

Returns

mixed

getConfigOrFail() public

getConfigOrFail(string $key): mixed

Returns the config for this specific key.

The config value for this key must exist, it can never be null.

Parameters

string $key

The key to get.

Returns

mixed

Throws

InvalidArgumentException

getLogger() public

getLogger(): Cake\Error\ErrorLoggerInterface

Get exception logger.

Returns

Cake\Error\ErrorLoggerInterface

handleError() public

handleError(int $code, string $description, string|null $file = null, int|null $line = null, array<string, mixed>|null $context = null): bool

Set as the default error handler by CakePHP.

Use config/error.php to customize or replace this error handler. This function will use Debugger to display errors when debug mode is on. And will log errors to Log, when debug mode is off.

You can use the 'errorLevel' option to set what type of errors will be handled. Stack traces for errors can be enabled with the 'trace' option.

Parameters

int $code

Code of error

string $description

Error description

string|null $file optional

File on which error occurred

int|null $line optional

Line that triggered the error

array<string, mixed>|null $context optional

bool

handleException() public

handleException(Throwable $exception): void

Handle uncaught exceptions.

Uses a template method provided by subclasses to display errors in an environment appropriate way.
