Class BaseErrorHandler
Base error handler that provides logic common to the CLI + web error/exception handlers.
Subclasses are required to implement the template methods to handle displaying the errors in their environment.
Properties summary
- $_config protected
arrayRuntime config
- $_configInitialized protected
boolWhether the config property has already been configured with defaults
- $_defaultConfig protected
arrayOptions to use for the Error handling.
- $_handled protected
bool - $logger protected
\Cake\Error\ErrorLoggerInterface|nullException logger instance.
Method Summary
- configShallow() public
Merge provided config with existing config. Unlike
config()which does a recursive merge for nested keys, this method does a simple merge. - increaseMemoryLimit() public
Increases the PHP "memory_limit" ini setting by the specified amount in kilobytes
- wrapAndHandleException() public
Checks the passed exception type. If it is an instance of
Errorthen, it wraps the passed object inside another Exception object for backwards compatibility purposes.
Method Detail
_configDelete() protected
_configDelete(string $key)
Deletes a single config key.

_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
$thisgetConfig() 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
mixedConfiguration 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
mixedConfiguration data at the named key
Throws
InvalidArgumentExceptiongetLogger() public
getLogger()
Get exception logger.
Returns
\Cake\Error\ErrorLoggerInterfacehandleError() 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
boolTrue 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
ExceptionWhen renderer class not found
