Yes, but looking for alternative array sorts in the manual will lead
you to arsort(). :-)


$a =3D array
(
1 =3D> '75',
2 =3D> '31',
3 =3D> '31',
4 =3D> '31',
5 =3D> '40',
);

$b =3D array
(
1 =3D> 'Personal Email',
2 =3D> 'Personal Phone',
3 =3D> 'Web site',
4 =3D> 'Text Message',
5 =3D> 'USPS mail',
);

$x =3D array_combine($b, $a);
var_export($x);
/*
array (
'Personal Email' =3D> '75',
'Personal Phone' =3D> '31',
'Web site' =3D> '31',
'Text Message' =3D> '31',
'USPS mail' =3D> '40',
)
*/

echo "\n";

arsort($x);

var_export($x);
/*
array (
'Personal Email' =3D> '75',
'USPS mail' =3D> '40',
'Text Message' =3D> '31',
'Web site' =3D> '31',
'Personal Phone' =3D> '31',
)
*/

?>
