FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Specification design pattern

This is my implementation of the "Specification" design pattern. It differs from the original one since i find it simpler and more straight forward.

It also allows the composition of multiple Specifications that takes in different types of parameters

The Goal of this pattern is to have separate classes of logic in order to do condition composition without rewriting and maintaining the conditions at different places.

Here is a detailed "how to" for thi package :

Creating a Specification

Create a class that implements the SpecificationInterface and that holds your logic :

Here is basic example of a list of specifications that checks differents things about products and customers

A class the checks if a product is available :

A class the checks if a product can be shipped to the customer :

A class the checks if a product is special (a special product is supposed to be (magically?) always in stock)

A class that checks if a customer is not blacklisted

All the available operators :

2.1 - isSatisfiedBy

One of the tree entry points of the specification pattern.
It Has to be used before any operator.
If used after an operator it will throw a WrongUsageException

Example :

2.2 - isSatisfiedByAll

the second possible entry point of the specification pattern.
Checks if all the Specifications sent are Valid ones (equivalent to chaining and operators)
It Has to be used before any operator.
If used after an operator it will throw a WrongUsageException

Example :

2.3 - isSatisfiedByAny

the third and last possible starting point of the specification pattern.
Checks if one of the Specifications sent is a Valid one (equivalent to chaining or operators)
It Has to be used before any operator.
If used after an operator it will throw a WrongUsageException

Example :

2.4 - and Operator

adds an '&&' condition to the previously set specifications
It can not be used first or else it will throw a WrongUsageException

Example :

2.5 - andNot Operator

adds an '&& !' condition to the previously set specifications
It can not be used first or else it will throw a WrongUsageException

Example :

2.6 - or Operator

adds an '||' condition to the previously set specifications
It can not be used first or else it will throw a WrongUsageException

Example :

2.7 - orNot Operator

adds an '|| !' condition to the previously set specifications
It can not be used first or else it will throw a WrongUsageException

Example :

2.7 - xor Operator

adds a 'xor' condition to the previously set specifications
It can not be used first or else it will throw a WrongUsageException

Example :

2.7 - xorNot Operator

adds a 'xor !' condition to the previously set specifications
It can not be used first or else it will throw a WrongUsageException

Example :

3- Composition

The specifications can be composed :

Example:
