PHPMaster.com:
Data Structures for PHP Devs Trees
July 08, 2013 @ 11:20:29

PHPMaster.com has posted their second article in their "data structures" series, this time focusing on trees - a structure for effectively storing related data in an easier to access format.

In a previous article I introduced two basic data structures: stack and queue. The article was well received so I've decided to share data structures in an intermittent on-going series here at PHPMaster. In this entry I'll introduce you to trees, another data structure used in software design and architecture.

He helps you get your head around the concept of trees using the idea of searching data, nothing that a stack or queue aren't exactly the right tools for the job. He talks about the basic concepts behind trees including "leaves" and "root nodes." He includes sample code showing how to make a simple node, insert some child nodes and "walking the tree" to find the information you're looking for.
