Question

I’m trying to email $msg = print_r($_POST, true);. 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?

Edit: I can see in the email source that the print_r message is 5 lines. But not on the user interface (Gmail).

You’re probably getting it as HTML, in which case you need to surround it with a proper HTML tag:

$msg = '<pre>' . print_r($_POST, true) . '</pre>';

Where <pre> is the preformatted text tag.

An alternative to this is to use nl2br() on the $msg, but it still won’t look quite right as you want a monospaced font, which <pre> already gives you.
