Answer 1

You want to concatenate $content.

Change

foreach($orders as $order) {
   $content = ....
}

to

foreach($orders as $order) {
   $content .= ....   // here-> .= 
}

Answer 2

You are overwriting the value of $content until the foreach() loop ends.So for now it's only displaying the last value that was assigned to $content inside the foreach() loop.

There are two things that you can do basically.

1.Assign the values into an array.

foreach($orders as $order) {    
$content[] = "Qty Description\r" . $order->Quan . " " . " " . " " . $order->Description . "\r";
}

By this method all the values that you are getting from the loop will be stored inside the array.

2.concatenate the values in $content

foreach($orders as $order) {
     $content .= "Qty Description\r" . $order->Quan . " " . " " . " " . $order->Description . "\r";
  }

I hope this will help you.
