I have said some not very nice things about PHP on this blog, and I’m sure over time I’ll be adding more such criticisms. This time I’d like to highlight a handy little feature in PHP, one that is a great deal easier to use than it’s Java counterpart.

Shuffling the elements in an array is probably a programming exercise in every single 1st year computer science textbook, it’s easy enough to do, but because it’s been done roughly 100 million times before, it feels moronic doing it again. So it’s nice when programming languages offer it as standard language functionality. PHP does by way of the shuffle() function and Java does by Collections.shuffle() static method. Seems simple enough, except that an array is not a collection in Java. So you can’t take your int[] and shuffle the elements quite so easily.

If you have an Integer[] in Java you can just pass it into Arrays.asList(array), get the collection and shuffle it. Uh oh, I said Integer[] which sadly is not the same as an int[]! So the difference between the two means I’m going to need to convert all the elements of the int[] into a Integer[] before I can shuffle it, geez, if I have to iterate the list once to convert type, I may as well just not put them back where I found them!

So this is me admitting there is an advantage to a dynamic language. I maintain I’d still rather pay the upfront cost of a few extra lines of code here-and-there for type safety, try getting a PHP IDE to reliably autocomplete instance methods for you, when it doesn’t know the type of a variable! Perhaps I need to start using Eiffel…

Everyone with a Magento store will recently have seen the notification that a possible CSRF attack against the Magento admin interface has surfaced. I thought I would take this opportunity to give a quick overview to CSRF(Cross-site request forgery) attacks, particularly how they work against web administration panels such as Magento and ways to protect Magento and other web applications from these sort of attacks.

The CSRF Basics

The easiest way to explain the attack is to think about what is happening under the hood when you are navigating a web page. You browser makes requests to the remote server for content, and to manipulate data stored on the server. In a strict RESTful approach to web applications, your browser will make GET requests when you are reading information and POST or PUT requests when you are creating or updating information.
