    That's because you're concatenating.  When appending to a
variable, you can't use constructs and conditions, unless using

. (!empty($beefolives) && is_numeric($beefolives) ? 'Order: beefolives
'.$beefolives : null)

    However, for readability and ease of management, you might want to
try something like this.  It makes at least two assumptions: you're
using a form post, and you understand that it's untested (as I'm just
typing it here into the body of this email).

// If we've posted our order
if (isset($_POST) && is_array($_POST['order'])) {

        // Instantiate the $order variable
        $order = null;

        // Iterate the order quantities
        foreach ($_POST['order'] as $k => $v) {

                // If the field is set and the amount is a number
                if (isset($v) && is_numeric($v)) {

                        $order .= 'Order: '.$k.': '.$v.PHP_EOL;

         * Note: in your example, you used single (literal)
         * quotes and included the variables.  That would
         * literally print $fname and $lname.
        $msg  = 'Name: '.$_POST['fname'].' '.$_POST['lname'].PHP_EOL;
        $msg .= 'Phone: '.$_POST['phone'].PHP_EOL;
        $msg .= 'Email: '.$_POST['email'].PHP_EOL;
        $msg .= PHP_EOL;
        $msg .= $order;

        // And then handle the rest of your processing.  Here, we just echo.
        echo '<pre>'.PHP_EOL.$msg.'</pre>'.PHP_EOL;
