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.
Please rate this library. Is it a good library?

Installation

Install through Composer.

How to use

To use Northern\Serializer you need to import it:

You can now instantiate and run the serializer on any PHP object:

However, without having annotated $someObject's class, nothing will be serialized. Let's annotate the class of which $someObject is an instance:

We have now annotated our class and indicated that the $myProperty attribute must be serialized as an integer. When we now serialize $someObject (which is assumed to be an instance of SomeClass) the $array variable will contain the serialized data:

Easy as.

With Northern\Serializer you can also serialize methods. Usually a serialized method is a getter of some sort. Let's look at an example:

As the above demonstrates, by simply adding the correct annotation to the method, the output of the method will be serialized as the key set by the annotation name parameter, which is myValue in our example:

If the name attribute is not specified on the annotation then the name of the method will be used as the serialization key, e.g:

Which will produce:

Serializing properties and methods are of course very handy but what about a nested object? Can do too:

Notice the Serialize\Object annotation? Be careful with recursive references!

Reference

These are the available serialization types:

Type Description
Serialize\Bool Serializes a boolean value.
Serialize\Int Serializes an integer value.
Serialize\Object Serializes an object. Indicates recursion.
Serialize\Collection Serializes an iterable, e.g. an array of objects.
