I'm delighted to announce that my new video course on Object-Oriented PHP is now available on Learnable! It's very much an introduction, aiming to cover WHY objects are so cool as well as how to declare and use one. The course is a mix of video (filmed in my kitchen, welcome to my home everyone!), screencast, a couple of exercises for you to try, and also plenty of sample code to download. If you are just looking to get started with OOP, or know someone who is, then hopefully this will help you out.
On a related note, I'm also doing a Sitepoint "Talk with the Experts" session on 11th April (early morning UK time, as a special treat for everyone in Europe and further east, that doesn't happen often!). There are more details here: http://www.sitepoint.com/forums/showthread.php?1012242-Talk-Object-oriented-PHP-with-the-Experts and I hope you can join me then.
Quick post because this tripped me up the other day: When you use a vanilla ubuntu 12.10 "Quantal Quetzal" installation, it will come with PHP 5.4, which is excellent news. However the default php.ini doesn't set the timezone, so you will see an error like:
It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.
These have been warnings in earlier versions of PHP, but as of PHP 5.4, the
date.timezone ini setting must be set correctly, using the continent and place - for me that's "Europe/London", like this:
date.timezone = "Europe/London"
If you see these errors, don't panic, just add the line above to your php.ini.
In case you haven't been following, FOSDEM is a Free Software/Open Source weekend event held every year in Brussels - it's free to attend and it's huge! It's actually a network of smaller events, and this year that includes a whole day of PHP on the Saturday (2nd February 2013). Our schedule is excellent, taking in frameworks, extensions (tutorial from Sara Golemon!), nginx, APIs and a few other goodies. Also, this lovely one-day PHP conference is in the wider context of an event that is packed full of otehr excellent open source technology sessions - see the full schedule for what else is on offer. I love these open source events for the opportunity to dip into not-PHP topics, and I hope to see you in Brussels! Come along, be geeky, and bring your friends :)
This post forms part of a series of articles about using PHP to do objected oriented programming, or OOP. They were originally published elsewhere but are no longer available at that location, so I'm reposting them here. Previously in the series was an introduction to OOP in PHP, in two parts
The title is a bit of a red herring as PHP has more than 9 magic methods, but these will get you off to a good start using PHP's magic methods. It might be magic, but no wands are required!

This post follows an earlier entry introducing the basics OOP and what that looks like in PHP. This time around we'll look at some more advanced concepts and some more practical examples of building code, covering use of constructors and how to add access modifiers in to control how calling code can operate on your objects. We'll also show off how to create static methods and properties and, perhaps more importantly, illustrate applications of these features.
There's an excellent open source conference that happens every year in Brussels in February, called FOSDEM. It consists of some main tracks, plus a series of sub-rooms, where various technical communities are given some space to use for whichever talks they choose; the schedules are centralised so that people can pop in and visit any talks in any room that looks interesting. This year, for the first time, this includes a "PHP and Friends" room - I'll be organising this and I'm looking for your input, please.
Basically, we need to get some great submissions, so that when we come to choose the schedule (and it is only one track, one day, there's only a few slots available), we can put together something really fitting to showcase PHP for a wider audience than a PHP conference. Selection will be done on the basis of talk topic, abstract and length in the first instance - we'll only take into account the actual speakers when we're curating the final list.
Key things you need to know:
- link to call for papers form (google forms)
- Event is 2nd (and 3rd, but the PHP room is on the 2nd) of February 2013, at ULB campus Solbosh in Brussels, Belgium
- No expenses will be covered by the event
- There's also a Call for Stands if you have a project that you would like to represent there
- If you're not speaking, come and join us anyway!

Since the introduction of PHP 5 in 2004, PHP has had an object model worthy of that description and became a truly modern language for use on the web. Earlier PHP scripts would have been of the kind where, to quote from Alice's Adventures, you would "Begin at the beginning, and go on till you come to the end: then stop." Nowadays that very procedural approach is less common in PHP, so this article takes a look at some of the basic object oriented features available in the language and shows some examples of using them with code examples.
As with most tools that work really well, I know very little about PEAR. I mean, I use it all the time, and I love it for getting all the extensions installed that I need for the work I do. But I've never made a PEAR package, or channel, and I've been happy to leave all those things in the hands of the smart people who have created what we have today.
However I'm now in a situation where I might need to install PEAR packages with a connection that may or may not be working, and I'm not sure exactly which packages I might need, so I wanted to know whether I could use PEAR as my packaging tool even when I wasn't able to reach the usual channels. And guess what? I can! Continue reading
I had an issue this week on a system which has been working fine for a while, but stopped fetching some data from google's user account API. I was getting a 403 response from the API, which seemed odd. Luckily I was logging
OAuth::getLastResponse() to my error logs (this is PHP code, and you need to call
OAuth::enableDebug() before you make the request to get this output) so I could see that I was getting the following back from Google:
SSL is required to perform this operation.
Closer inspection shows that for one of the google endpoints, I had a prefix of
http:// rather than
https://. Those single-character bug fixes that take hours to find are my favourite!
