_displayError() abstract protected

_displayError(array $error, bool $debug)

Display an error message in an environment specific way.

Subclasses should implement this method to display the error as desired for the runtime they operate in.

Parameters

array $error

An array of error data.

bool $debug

Whether or not the app is in debug mode.

_displayException() abstract protected

_displayException(\Throwable $exception)

Display an exception in an environment specific way.

Subclasses should implement this method to display an uncaught exception as desired for the runtime they operate in.

Parameters

\Throwable $exception

The uncaught exception.

_logError() protected

_logError(mixed $level, array $data)

Log an error.

Parameters

int|string $level

The level name of the log.

array $data

Array of error data.

Returns

bool

_stop() protected

_stop(int $code)

Stop the process.

Implemented in subclasses that need it.

Parameters

int $code

Exit code.

configShallow() public

configShallow(mixed $key, mixed $value)

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

string|array $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 $key, mixed $default)

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

Configuration data at the named key or null if the key does not exist.

getConfigOrFail() public

getConfigOrFail(string $key)

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

Configuration data at the named key

Throws

InvalidArgumentException

getLogger() public

getLogger()

Get exception logger.

Returns

\Cake\Error\ErrorLoggerInterface

handleError() public

handleError(int $code, string $description, ?string $file, ?int $line, ?array $context)

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|null $context optional

Context

Returns

bool

True if error was handled

handleException() public

handleException(\Throwable $exception)

Handle uncaught exceptions.

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

Parameters

\Throwable $exception

Exception instance.

Throws

Exception
When renderer class not found
