Looks like there are some errors in your code. First, by setting $c to 0 by default and using that as an array index you are assigning the alphabetically first country to that slot, not USA. Worse still, when you actually reach the row with USA on it, you don’t add it to the existing array, instead you overwrite the array by assigning a new array.

I suggest that you don’t use $c at all. Instead start with an empty array, add USA to the front of the array, and all other countries to the end of the array. As for arranging the records, that is easiest to do with the SQL query. The below code assumes the column with the country name is called name – if it is not, you can fix this yourself.

<?php
require 'dbconnect.php';
// Create empty array
$message=array();

$query="SELECT * FROM phpfox_country ORDER BY name ASC";
$result=mysql_query($query);

if($result)
{
    while($row=mysql_fetch_row($result))
    {
        if($row[1]=="United States")
        {
            // Add to start of the array
            array_unshift($message, array("country_iso"=>$row[0],"name"=>$row[1]));
        }
        else
        {
            // Add to end of the array
            $message[]=array("country_iso"=>$row[0],"name"=>$row[1]);
        }
    }
}
else
{
    $message=array("message"=>"error in code");
}
echo json_encode($message);
?>
