mail() php doesn't send in html format

Question

I tried questions already answered over here (this, this, this, and others...), but nothing get worked... i have this function to send an email:

function send_email($para, $assunto, $msg){
    $to      = $para;
    $subject = $assunto;

    $message = '<html><body>';
    $message .= str_replace("\\r\\n","<br/>",$msg);
    $message .= '</body></html>';

    $headers = 'From: [email protected]' . "\r\n";
    $headers .= 'Reply-To: [email protected]' . "\r\n";
    $headers .= 'X-Mailer: PHP/' . phpversion() . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
    $headers .= 'MIME-Version: 1.0' . "\r\n";

    return mail($to, $subject, $message, $headers);
}

And i'm calling this with something like that:

$var = "<p><strong>...blablabla...</strong></p>";

send_email("email@email", "lalala", $var);

I can send the email, but it ins't html formatted (and it contains the html tags, except for HTML and BODY). What am i doing wrong?

EDIT 1: The email is displayed like this (exactly the same content sent, except for HTML and BODY TAG):

BEGIN
<p><strong>...blablabla</strong></p>
END

When i get the full email (like this tutorial), shows up that the email was sent with TAGS html, body, etc... A piece of the email:

Delivered-To: [email protected]
...
To: [email protected]
Subject: aaaaaaaaaaaaaaaaaaaaa
From: [email protected]
Reply-To: [email protected]
X-Mailer: PHP/5.6.19

could you eventually also copy/paste here the resulting e-mail message with headers and all? — Dragos

Other then the headers being in incorrect order your code looks fine. Maybe there is a problem on the client side, which mail client are you using? — erikvimz

Try changing Content-type to Content-Type (upper case the T). — Ross

@PMateus E-mail, proper MIME encoding, and multi-part messages are an utter nightmare and you would be crazy to have to figure out all the quirks yourself. :-) Use an existing mail library that does this for you, such as PHPMailer or similar. — Brad

Not sure if this is an exact solution, but this solved html email problems I was having with Microsoft Outlook.

Replace all of the \r\n in the headers with PHP_EOL. I did this when I was having issues with sending html emails in PHP, and it seemed to solve my particular problems.

PHP_EOL changes its value depending on the platform you're using. If you run PHP on Windows, you'll get \r\n. If you run it on Linux, you'll get \n.
