Try this:
-----------
$mi_boston = 645; //would be a calculation I guess
$mi_ny = 886; //would be a calculation I guess
$mi_chicago = 423; //would be a calculation I guess
$mi_la = 1087; //would be a calculation I guess
$arr_places = array(
'0' => array(
'City' => 'Boston',
'State' => 'Massachusett' ,
'ZipCode' => '11111' ,
'mileage' => $mi_boston ,
),
'1' => array(
'City' => 'New York',
'State' => 'New York' ,
'ZipCode' => '11221',
'mileage' => $mi_ny ,
),
'2' => array(
'City' => 'Chicago',
'State' => 'Illinois' ,
'ZipCode' => '33333',
'mileage' => $mi_chicago ,
),
'3' => array(
'City' => 'Los Angeles',
'State' => 'California' ,
'ZipCode' => '99999',
'mileage' => $mi_la ,
),
);
//echo AS IS - just shows what it looks like before the mileage sort
while ( list($key, $val) = each($arr_places) ) {
echo "<p>$val[mileage] - $val[City], $val[State]
$val[ZipCode]</p>\n";
}
reset ( $arr_places );
echo "\n<p> </p>\n\n"
//echo with a multisort
//(Make the sort array out of the "mileage"
while ( list($key, $val) = each($arr_places) ) {
$sortarray[] = $val[mileage];
}
reset ( $arr_places ); //probably not necessary but we'll do it anyway
//sort ascending numerically by the "mileage" $sortarray
array_multisort($arr_places,SORT_ASC,SORT_NUMERIC,$sortarray);
while ( list($key, $val) = each($arr_places) ) {
echo "<p>$val[mileage] - $val[City], $val[State]
$val[ZipCode]</p>\n";
}
