Sorting a Multi-Dimensional Array with PHP. Every so often I find myself with a multidimensional array that I want to sort by a value in a sub-array.
I have an array that might look like this: //an array of some songs I like $songs = array( '1' => array('artist'=>'The Smashing Pumpkins', 'songname'=>'Soma'), '2' => array('artist'=>'The Decemberists', 'songname'=>'The Island'), '3' => array('artist'=>'Fleetwood Mac', 'songname' =>'Second-hand News') ); The problem is thus: I’d like to echo out the songs I like in the format “Songname (Artist),” and I’d like to do it alphabetically by artist.

It’s really no surprise either, as consuming REST APIs is so incredibly easy… in any language.

So, What on Earth is REST? Before we get into writing some code, I want to make sure everyone’s got a good understanding of what REST is and how its great for APIs.
Requests All APIs need to accept requests. Social Network Style Posting with PHP, MongoDB and jQuery - part 1. Post mechanisms similar to Facebook are nowadays very common within any application.

I’m guessing that if you are reading this post you have already encountered the problem of the same origin policy with regards to retrieving data with AJAX from urls in other domains than your’s (the requesting domain).
This policy, enforced by browsers, means you cannot fetch raw data from other domains with straight AJAX calls. The Problem I Was Trying To Solve (skip this paragraph if you just want the solution) Here’s the situation I ran into. At work, we have a timesheet entry program running on one subdomain, and Flyspray (bug-tracking software) on another subdomain.

The Problem Safari does not allow cross-domain cookies. In other words, if on X.com, you load an iFrame with contents of Y.com and set a cookie in the iFrame, Safari will not save the cookie. This problem also occurs in IE6/7 but can be resolved by sending a P3P header. The Solution I am not entirely sure why this works, but the cookie gets saved if a post is made to the iFrame.
Here is the code that goes on the remote domain: The contents for startsession.php would be as simple as: To make sure that your site is compatible with IE6/7, always output the following header: [PHP] Les ressemblances à ne pas confondre. Introduction Cette astuce présente plusieurs fonction ou astuces en php qui sont différentes alors que beaucoup de monde croit qu'elles agissent de la même façon. Concaténation ou paramètres ? Avec la fonction echo (ou print), on peut afficher plusieurs variables et chaines de caractères à la suite.
Exemple : Ici, on utilise la virgule entre la chaine de caractères et la variable. Lorsque l'on utilise des points, on apelle ça la concatenation. J'ai testé les deux méthodes, et le passage de plusieurs paramètres est assurément plus rapide. Voici d'ailleurs une page de test ou sont comparés les deux méthodes : Cependant, les virgules ne peuvent être utilisés qu'avec un echo ou un print, contrairement à la concaténation.
