FAQ
Example:
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 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.
Informations about the package enum
PHP Enum
THIS PACKAGE IS A FORK OF Spatie/Enum to allow for PHP 7.1 support.
This package offers strongly typed enums in PHP. We don't use a simple "value" representation, so you're always working with the enum object. This allows for proper autocompletion and refactoring in IDEs.
Here's how enums are created with this package:
And this is how they are used:
Installation
You can install the package via composer:
Usage
This is how an enum can be defined.
This is how they are used:
Creating an enum from a value
Override enum values
By default, the string value of an enum is simply the name of that method.
In the previous example it would be draft.
You can override this value, by adding the $map property:
Mapping values is optional.
Note that mapped values should always be strings.
Comparing enums
Enums can be compared using the equals method:
You can also use dynamic is methods:
Note that if you want auto completion on these is methods, you must add extra doc blocks on you enum classes.
Enum specific methods
There might be a case where you want to have functionality depending on the concrete enum value.
There are several ways to do this:
- Add a function in the enum class and using a switch statement or array mapping.
- Use a separate class which contains this switch logic, something like enum extensions in C#.
- Use enum specific methods, similar to Java.
This package also supports these enum specific methods. Here's how you can implement them:
By declaring the enum class itself as abstract, and using static constructors instead of doc comments, you're able to return an anonymous class per enum, each of them implementing the required methods.
You can use this enum the same way as any other:
Note that one drawback of this approach is that the value of the enum is always the name of the static function, there's no way of mapping it.
