array sorting

[anups]

How to sort PHP2d Array using upon key.  eg.

I have a array of

$users[0]['name'] = "abc"

$users[0]['age'] = "12"

$users[0]['sex'] = "M";

 

$users[1]['name'] = "xyz"

$users[1]['age'] = "15"

$users[1]['sex'] = "M";

 

$users[2]['name'] = "pqr"

$users[2]['age'] = "16"

$users[2]['sex'] = "F";

 

Now I have to sort in on age or 'sex',

Use usort to define a function that will perform the sorting logic:

 

 

function sortByAge($a, $b){    if ($a['age'] == $b['age'])    {        return 0;    }    return ($a['age'] < $b['age']) ? -1 : 1;}usort($users, 'sortByAge');
