Sorting a Two Dimensional Array

[StevePBurgess@gmail.com]

Hi. I have an array, thus:

Array (
[0] => Array ( [Freq] => 28 [Name] => Tomato )
[1] => Array ( [Freq] => 4 [Name] => Banana )
[2] => Array ( [Freq] => 54 [Name] => Orange )
[3] => Array ( [Freq] => 24 [Name] => Eggplant )
[4] => Array ( [Freq] => 5 [Name] => Courgette )
[5] => Array ( [Freq] => 4 [Name] => Apple )
)

I would like to be able to sort it either by the Frequency or the Name
of the fruit or vegetable.

I just can't seem to get it to work. I'm sorry - I realise that this is
probably really easy but my brain isn't working today and the examples
on php.net seem incomprehensibl e to me.

Many thanks, in anticipation

Steve

// $key = 'Freq';
$key = 'Name';

function callback($a, $b) {
global $key;
if ($a[$key] == $b[$key]) return 0;
return $a[$key] > $b[$key] ? 1 : -1;
}
uasort($array, 'callback');

First of all, you need to give people a chance to answer - at least 24 hours.
We're all volunteers and some only check in once a day.

To answer your question, no.

$xx=array(array (1,2),array(3,4 ));
echo $xx[0][0]; // prints 1
echo $xx[1][1]; // prints 4

Which also follows you can do this:

$xx[0][0]="X";
echo $xx[0][0];
