Informations about the package fallback
DEPRECATION NOTICE: this package has been moved and improved at grizz-it/fallback
Ulrack Fallback
This package contains an implementation for implementing a fallback system within a PHP application.
Installation
To install the package run the following command:
Usage
A single fallback consists of one FallbackStack with multiple Fallbacks.
Creating a Fallback
A fallback can be created by providing it with a callable, a (optional) validator and a (optional) set of parameters. The callable will be executed when it is reached inside the stack. The validator (see package: ulrack/validator) will be used to verify the output of the callable. The parameters are variadic and will override the parameters send by the stack.
An implementation would look like:
The fallback stack can be created after this. The fallback stack takes a
validator as an argument. The function addFallback is used to add the fallback
to the stack. This function takes the Fallback and a position as its arguments.
The stack can then be invoked with a set of parameters.
