On the MongoDB blog there's a new post starting off a series called "MongoDB for the PHP Mind", a look at using this popular NoSQL database from PHP. In this first post of the series, Mitch Pirtle covers things from a post-install and configure perspective.
We have covered a lot on the blog about MongoDB features, as well as many ways to utilize MongoDB from different languages. This is the first in a series of posts from the perspective of a PHP developer; and covers the gamut from getting started to advanced concepts.
He links to some guides for getting the database and the PHP extension installed and starts in to define some common terminology. He shows how to create queries to look for certain terms across multiple data points and how to port those over to the PHP side using the extension's features.
