might be a cleaner, more elegant way to do it. In Java, you just
need to
implement the interface Comparable and provide a method called
compareTo (as
far as i remember) and then you can use one of the many sorting
algorithms
generically on objects that are comparable...
Anyway, I didn't find something like that for PHP. Since I'm using
symfony,
I had a bit of a play with the objects at hand and simply did a
sort($arrayOfObjects) and it did sort them by the id. Just wondering
where
it got the information on what to sort on (not quite) correctly for
my case?
I'm confused. The function you need is the one you mention in the
subject. All you need to do is create a function that compares two of
the objects, in whatever way you need it to, and returns -1, 0 or 1.
The pass that to the usort function - it doesn't care what type of
thing is in the array. Full details available at http://php.net/usort.
