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?

Informations about the package one-to-many-iterator

One-to-many iterator

Helper iterator and generator for one-to-many joins.

Overview

When you want to fetch a one-to-many relation, you're probably using a JOIN to avoid the N+1 selects problem.

Though, it may be difficult to iterate over the result, especially when you need the whole "many" part of the relation loaded for a process.

This is why I created this tiny library. It takes a Traversable of arrays, having a common key to distinguish the "one" part of the one-to-many relation, and sorted on this key (so it can yield items in streaming, without loading the whole set in memory).

It will then aggregate the "many" part of the relation in a configurable key.

Installation

Examples

Your database result iterator, once converted into an array, looks like this (a typical JOIN):

But you'd like to iterate over something like this:

To achieve this, just pass your database result to Val\Iterator\OneToManyIterator or Val\Iterator\OneToManyGenerator, while configuring the common key (here, id), and aggregate key (here, children).

Assuming $result contains the raw SQL result iterator:

The difference between the iterator and the generator, is, well.. that the former implements a raw PHP iterator while the latter uses a PHP generator (available since version 5.5).
