Sorting Array in array variable

Question

I have an array like this

$data = array(
    array(
    'name'=>'guguk',
    'nilai'=>3
    ),
    array(
    'name'=>'gogok',
    'nilai'=>7
    )
);

so, how should I do to sort array base on attribute 'nilai'?

Answer 1

You can use usort.

Try this

function cmp($a, $b) {
        return $a["nilai"] - $b["nilai"];
}
usort($data, "cmp");
echo '<pre>'; print_r($data); echo '</pre>';

Answer 2

you can create code like

    array_multisort($ar1, $ar2);
