echo "<pre>"; doesn't work

I follow this video by adding this code echo "<pre>;
$email_body =" "; $email_body .= "Name " . $name ; $email_body .= "Email " . $email ; $email_body .= "Details " . $details"; echo $email_body; echo "</pre>";

but the result does not have a line break as the tag <pre> should do. Why is that?

Hi nanchaporn krombas,

In this example I have noticed she is using "\n", which gives you a line break.

<?php
echo "<pre>";
$email_body =""; 
$email_body .= "Name " . $name . "\n"; 
$email_body .= "Email " . $email . "\n";
$email_body .= "Details " . $details . "\n"; 
echo $email_body; 
echo "</pre>";
?>

I recommend using the "<br />\n", on this topic though does it create a vulnerability not catching the tabs and sending a blind map of entry and exits in the source? I might be crazy enough if I had a malicious bone in my body, try to work out whats going on at these non-indented spaces. So do I use tabs or spaces? lol
