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.

  • 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.

Informations about the package eloquent-exists-relation

DESCRIPTION

Add an attribute that indicates whether there is an element indicated by the relation specified when acquiring to the Eloquent Model using a subquery. It is similar to withCount, which finds the number of elements of a relation, but it differs in obtaining only whether it exists without counting.

INSTALL

This package is compliant with Package Discovery so no additional configuration is required.

In case of Lumen

Register EloquentExistsRelationProvider as follows in bootstrap/app.php.

USAGE

If you want to know wheather results from a relationship exists without actually loading them you may use the withExists method, which will place a {relation}_exists column on your resulting models. For example:

You may add the "exists" for multiple relations as well as add constraints to the queries:

You may also alias the relationship exists result, allowing multiple exists on the same relationship:

TIPS

Since the value of EXISTS may not be a boolean value (for example, 0 or 1 in mysql), it is convenient to cast it explicitly when you want to treat it as a boolean value.
