I’m sending some data through xml code, problem is that in xml I want to send multiple with some data in it (It depends on product items quantity) have no idea what to do.

$number_array = $_POST['numbers'];
$name_array = $_POST['name'];
$quantity_array = $_POST['quantity'];
$price_array = $_POST['totprice'];

$output1 = ''.implode(' ',  $number_array).' ';
echo $output1;

$output2 = ''.implode(' ',  $name_array).' ';
echo $output2;

$output3 = ''.implode(' ',  $quantity_array).' ';
echo $output3;

$output4 = ''.implode(' ',  $price_array).' ';
echo $output4;

for ($i = 0; $i < count($name_array); $i++) {

$name = ($name_array[$i]);
$number = ($number_array[$i]);
$quantity = ($quantity_array[$i]);
$price = ($price_array[$i]);

}


$xml = '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
