PHP Build a Basic PHP Website (2018) Adding a Basic Form Redirecting After a Form Submission

Header Function Question

In the video, Alena reminds us that there must be no output before header function for the redirect to work. However, if we look at the code:

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

    //To Do: Send Email

Shouldn't the echo of $email_body and </pre> mess up the header function, stopping the redirect from happening?
