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.

fusonic/linq
fusonic/linq is a lightweight PHP library inspired by the LINQ 2 Objects extension methods in .NET.
For a full introduction read my blog-post: http://www.fusonic.net/en/blog/2013/08/14/fusonic-linq-write-less-do-more/
LINQ queries offer three main advantages over traditional foreach loops:
-
They are more concise and readable, especially when filtering multiple conditions.
-
They provide powerful filtering, ordering, and grouping capabilities with a minimum of application code.
- In general, the more complex the operation you want to perform on the data, the more benefit you will realize by using LINQ instead of traditional iteration techniques.
Requirements
fusonic/linq is supported on PHP 5.5 and up.
Installation & Usage
The most flexible installation method is using Composer: Simply create a composer.json file in the root of your project:

The aggregate method makes it simple to perform a calculation over a sequence of values:
The chunk method makes it simple to split a sequence into chunks of a given size:

Simple, Consistent and Predictable
One important design goal was the principle of the least surprise. As PHP is a fully dynamic language with nearly no type-safety, it is common to shoot yourself into the foot because of accidentally mixing up incompatible types.
We protect you from these programing errors by asserting that every callback functions you supply to the library must return a correctly typed value. In addition, every supported aggregate function will throw an exception if you are accidentally mixing up incompatible types.
This means that we made this library totally predictable in what it does, and verified that every function has its defined exceptions which are thrown when certain operations fail, or if certain types are not correct.
