sorting a 2d array

[Anon]

I have a 2D array which I would like to sort by the forst element of the inner array:

[[1,"stuff"],[3,"more stuff"],[2,"things"]]

And I need:

foreach($array as $element)
{
echo element[1]."<br>";
}

to print out:

stuff
things
more stuff

any ideas?

Well...just out of curiosity, why aren't you using a hash? You can just do this:

$myArray = array(2 => "More Stuff", 1 => "Stuff", 3 => "Even More");
sort($myArray);
foreach($myArray as $element)
echo $element . "<BR>\n";

By using a hash, you can specify a key to sort by, rather than using a multidimensional array.
