[PHP] Sorting Arrays of Associative Arrays?

[azizny]

Greetings all,

I have an array of associative arrays:

<? 

$list[0]['name'] = 'Testname'; 
$list[0]['userid'] = '111'; 
$list[0]['age'] = '11'; 

$list[1]['name'] = 'Testname2'; 
$list[1]['userid'] = '222'; 
$list[1]['age'] = '22'; 

$list[2]['name'] = 'Testname3'; 
$list[2]['userid'] = '333'; 
$list[2]['age'] = '33'; 

$list[3]['name'] = 'Testname4'; 
$list[3]['userid'] = '444'; 
$list[3]['age'] = '44'; 
?> 

How would I go on sorting the list by userid or age?

I also tried to do bubble sort, but it passed the allowed excuation time, and when I try to allow more it keeps on going ang going and going infinte?

I appreciate any help,

Peace,

$list[0]['name'] = 'Testname';  

$list[0]['userid'] = '111';  

$list[0]['age'] = '11';  

$list[1]['name'] = 'Testname2';  

$list[1]['userid'] = '222';  

$list[1]['age'] = '22';  

$list[2]['name'] = 'Testname3';  

$list[2]['userid'] = '333';  

$list[2]['age'] = '33';  

$list[3]['name'] = 'Testname4';  

$list[3]['userid'] = '444';  

$list[3]['age'] = '44';  

foreach ($list as $value)
{
	$age_sorted_list[$value['age']] = $value;
}
ksort($age_sorted_list);
print_r($age_sorted_list);
