Felix Geisendorfer has a quick little sorting example posted today showing on way to sort a multi-dimensional array.

Quick challenge, lets say you have an array and you want to iterate through your products by [the key of each subarray in $products] Product.ordering ASC. Whats the fastest way to do this?

His solution involves using an array_flip call on the extracted information (using Set::extract), ordering it with ksort and pushing the values back into the $product array in the right order.

Check out the comments for more examples including ones that make use of array_multisort.

On the HowToForge website, there's a new tutorial that teaches one of the fundamentals of working with PHP (or any language for that matter) - looping.

Let's move towards our today's lecture which is about Loops. There are certain conditions in which you need to execute the same block of code again and again. For example if you want to print ten consecutive equal signs in three lines to make a separator then you could do it with different methods.

The tutorial covers:

• Basic Concept Of Loops
• Types Of Loops (for, while, do/while, and foreach)
• Assignment
• some Related Articles

Code examples are given for all, and a good overview of working with the loops is given.
