My new job as a Developer Advocate with IBM means I get to play with databases for a living (this is the most awesome thing ever invented, seriously). On my travels, I spent some time with MongoDB which is a document database - but I ran into an issue with fetching a record by ID so here's the code I eventually arrived at, so I can refer to it later and if anyone else needs it hopefully they will find it too.

There's a new version of XHGui (well, a few months old) and it's fabulous! It's got a few new dependencies though so I thought I'd write down how I set up my version, in case it's helpful to anyone else (and so I feel like a pro next time I have to do this!). If you're not familiar with XHGui it's a fabulously easy and friendly way to profile your application; to understand which method calls in a page take the time and how many times they are made, so you can improve the performance of your application. All these instructions are for my 32-bit Ubuntu 12.10 system, hopefully they will work for you or you'll be able to adapt them as appropriate.
XHGui needs version numbers or fluffy animal names, because this is a really major release and quite different to what went before in both technology and in looks. In particular, it now uses MongoDB. If you're not familiar with MongoDB, it's a super-friendly NoSQL database that makes a really handy backend for this kind of unstructured data - because every run of every page will look different. Therefore you will need:
- MongoDB itself
- The pecl extension for mongo
- The xhprof pecl extension (

I'm enjoying working with MongoDB but as with any new technology, it can take a little while to find your way around all the tools related to that stack. In particular, I found myself wondering how do I
mysqldump for mongodb?
It should have come as no surprise that the command I wanted was called
mongodump, really! Continue reading
When I meet a new technology, I like to experience it "just as it comes". I'm happy at the command line and I like to type actual commands and see man pages before I use any wrappers or helper tools. So when I met MongoDB for the first time, I did exactly that. This post shows those first steps of creating a database, and inserting, reading, deleting and updating data.
