title: Emailing print_r with PHP
body: <p>I'm trying to email <code>$msg = print_r($_POST, true);</code>. When I receive the email the array doesn't look nice. Instead of 5 lines it shows it on one line. What can I do?</p>
  
  <p>Edit: I can see in the email source that the print_r message is 5 lines. But not on the user interface (Gmail).</p>
