Fixed it for you. Your looping is wrong, you need to look on $arr first to get each rows of data.

Try this:

<?php
// Your database configs here

$url = "http://demo.miliarta.com/cityapi/all/?dealerid=TEN000005&user=dealer&passwd=dealer&cityid=316";
$string = file_get_contents($url);
$arr = json_decode($string, true);

foreach($arr as $item){
    $cityid = $item['cityid'];
    $stateid = $item['stateid'];
    $cityname = $item['cityname'];
    $statename = $item['statename'];

    mysql_query("INSERT INTO city (cityid, stateid, cityname, statename) VALUES('$cityid', '$stateid', '$cityname', '$statename')") or die (mysql_error());
}
