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.

Informations about the package scalar

Wrapping object for scalar (or null) only

Build Status

PHP provide scalar type hinting since PHP 7.0, but no native function is able to protect us against value lost on cast.

For that reason, if we want to be sure about scalar type, a scalar converter and optionally a type-checking class are the only chance.

Warning: The converter and so the wrapper class does not cast null - it remains null.

Why the NULL remains NULL by default? Because it is the lesser evil, to do not force a type to an unknown value (which NULL is - the "unknown"). If you want to be sure about scalar type, use StrictScalar instead. But still, the NULL to scalar cast have to be done by you.
