Hello... I need some help with my PHP email form!

can anyone help???

here's my code:

<?php

if($_POST['name'] == "") {
echo "Please Insert Name:";
} elseif($_POST['email'] == "") {
echo "Please Insert Email";
} else {

if(isset($_POST['submit'])) {
$to = "

$subject = "Form Solicito Informação";
$subject2 = "É Obrigação";
$name = $_POST['name'];
$email = $_POST['email'];

$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: $email\r\n";
$headers .= "Reply-To: $email\r\n";

echo "blarg!";
}
header("Location: thank_you.php");

Thank you however help´s...Goodbye

try adding a charset to your header:



$header .= 'MIME-Version: 1.0' . "\n" . 'Content-type: text/plain; charset=UTF-8'
