How do I fill an array inside a while loop and get new scope each iteration?

The problem is that I get only the last value comming from the Table. I think its because I am building the array while referencing its values to the same object, and it keeps changing. I know while loop doesnt create a new scope for each iteration which IS the problem.

What's the best way to get a new scope for each iteration?

Code:

    $namesArray= array();
        while ($row=mysql_fetch_array($result))
        {
        $nameAndCode->code = $row['country_code2'];
        $nameAndCode->name = $row['country_name'];           
        array_push($namesArray,$nameAndCode);


        } 
return $namesArray;

You need to create a new object on each iteration:

while ($row=mysql_fetch_array($result))
{
    $nameAndCode = new stdClass;
    $nameAndCode->code = $row['country_code2'];
    $nameAndCode->name = $row['country_name'];           
    $namesArray[] = $nameAndCode;
}

Otherwise you're referencing the same object over and over, and just overwriting its values.

You also can do this with arrays if you don't require objects:

while ($row=mysql_fetch_array($result))
{
    $nameAndCode = array();
    $nameAndCode['code'] = $row['country_code2'];
    $nameAndCode['name'] = $row['country_name'];           
    $namesArray[] = $nameAndCode;
}

Or more concisely:

while ($row=mysql_fetch_array($result))
{
    $namesArray[] = array( 
        'code' => $row['country_code2'],
        'name' => $row['country_name']
    );
}

I'd go with something like:

$namesArray=array();
while($row=mysql_fetch_array($result)){
  $nameAndCode=array("code"=>$row["country_code2"],
                     "name" => $row["country_name"]);
  array_push(&$namesArray,$nameAndCode);
};

I'd also try passing $namesArray by reference, like Viktor mentioned. My code makes completely new array to push each iteration, which makes sure you dpn't overwrite stuff. Also, if you want to add stuff to an array by accessing it via its index you should use this:

// This is the right way
$someArray["foo"]="bar";
$someArray["baz"]="quux";
// This is wrong, it's only for OOP
$someArray->foo="bar";
$someArray->baz="quux";
