Sorting a multi array

[Paul Kirby]

Hello All

I am trying to update me code to use arrays to store a group of information
and I have come up with a problem sorting the multiple array :(

Array trying to sort: (7 arrays put into an array) and I want to sort on
[count] Descending.
This is displayed using print_r() function.

Array
(
[czero] => Array
(
[game_type] => czero
[game_label] => Condition Zero
[count] => 2
)
[cstrike] => Array
(
[game_type] => cstrike
[game_label] => Counter-Strike
[count] => 3
)
[dod] => Array
(
[game_type] => dod
[game_label] => Day of Defeat
[count] => 1
)
[valve] => Array
(
[game_type] => valve
[game_label] => Half Life
[count] => 0
)
[gearbox] => Array
(
[game_type] => gearbox
[game_label] => Opposing Force
[count] => 0
)
[ricochet] => Array
(
[game_type] => ricochet
[game_label] => Ricochet
[count] => 0
)
[tfc] => Array
(
[game_type] => tfc
[game_label] => Team Fortress Classic
[count] => 1
)
)

Does anyone know how to do this ?
I have tried various array sorting functions without success :(

If you require more information, then let me know.

Thanks in advance

See www.php.net/uasort and associated functions.

Re: Sorting a multi array

I think I found a variant of this under the usort function:

$sorted_array = arfsort($array, 'count');
or
$sorted_array = arfsort($array, array('count')) ; // can pass secondary
sort field in the 2nd param..

to get descending:
$sorted_array = array_reverse(a rfsort($array,a rray('count'))) ;



//arfsort() - (AR)ray (F)ield Sort.
//Sort a multi-dimensional array according to a list of fields.
//preserves keys
function arfsort( $array, $fields ) {
debug('<B>arfso rt(</B><B>)</B> [1.00 - 2005/05/26]');
if ( !is_array($fiel ds) )
$fields = array($fields);
$GLOBALS['__ARFSORT_LIST __'] = $fields;
uasort( $array, 'arfsort_func' );
unset($GLOBALS['__ARFSORT_LIST __']);
return $array;
}
//Internal sorting function for arfsort()
function arfsort_func( $a1, $a2 ) {
foreach( $GLOBALS['__ARFSORT_LIST __'] as $f ) {
if ( isset($a1[$f]) && isset($a2[$f]) ) {
$strc = strnatcasecmp( $a1[$f], $a2[$f] );
return $strc;
}
}
return 0;
}

Thanks to both of you that helped a little, had to alter bits of their
examples to fit my needs :)
