Create a blank HTML page. Add this code to it.
<!DOCTYPE HTML PUBLIC "-//W3C/DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>Contact Me</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<!-- you can put other meta tags here if you wish -->
</head>
<body>
<p>You may contact me using the below form.</p>
<form method="post" action="process.php">
<dl>
<dt>Name:</dt>
<dd><input type="text" name="name"></dd>
<dt>Email Address:</dt>
<dd><input type="text" name="email"></dd>
<dt>Message:</dt>
<dd><textarea name="message"></textarea></dd>
<input style="display: block;" type="submit" value="Submit">
</dl>
</form>
</body>
</html>
Then, make a blank PHP page. Save it as process.php then add this code to it:
<?php
$name = $_POST['name'];
$email = $_POST['email'];
$message = $_POST['message'];
$to = "YOUR EMAIL ADDRESS HERE"; // the email address to send it to
$re = "Comment submitted from your web site"; // The subject of the email that will appear in your inbox
$msg = " Name: $name \n
E-mail: $email \n
Message: $message ";
mail( $to, $re, $msg );
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>Message Sent!</title>
</head>
<body>
<h1>Message Sent!</h1>
</body>
</html>
If that doesn't work, search Google (http://www.google.com/search?biw=1163&hl=en&q=PHP+contact+form&btnG=Google+Search) for PHP contact forms.
