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.

_displayError() ¶ abstract protected
_displayError(array $error, bool $debug): voidDisplay 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.

-
bool$debug Whether or not the app is in debug mode.
Returns
void_displayException() ¶ abstract protected
_displayException(Throwable $exception): voidDisplay an exception in an environment specific way.

Implemented in subclasses that need it.
Parameters
-
int$code Exit code.
Returns
voidconfigShallow() ¶ public
configShallow(string|array $key, mixed|null $value = null): $thisMerge 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|null $key = null, mixed $default = null): mixedReturns 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): mixedReturns the config for this specific key.
The config value for this key must exist, it can never be null.

Parameters
-
int$code Code of error

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): voidHandle uncaught exceptions.
