Sorting Multidimensional Arrays

Sorting multidimensional arrays

Help!

I am trying to analyse stored customer enquiries by month and country of origin. The total enquiries for each country and month are contained in an array in the format...

$country[$x][$z]

...where $x is the month (1-12) and $z is a country code (1-200).

I need to list the contents of the array by month, in ascending order, and by the value of the country column, in descending order.

I have spent a day trying to get my head around the various array sort functions and failed miserably.

HELP please! thanks in anticipation.

take a look at this

<?
$country[0] = array(5,98);
$country[1] = array(3,11);
$country[2] = array(2,199);
$country[3] = array(1,43);
$country[4] = array(4,126);

echo '<p><pre>before sort:<br>';
print_r($country);
echo '</pre>';

array_multisort($country,0);

echo '<p><pre>after sort:<br>';
print_r($country);
echo '</pre>';

?>
