Parse Error in unexpected T_Variable. Subscription Mail Form - php

Question

So I have this form.
Its a very simple mail/newsletter form.
<form action="http://localhost/website/subscribe.php" method="POST" id="signup_form">
<label for="email"><p id = "subText">Subscribe</p></label>
<input type="text" name="email" size="30" class="required email txtEmail" placeholder = "Enter Email Address">
<input type="submit" value="Go" name="submit" class = "goButton"/>
</form>
and I have this subscribe.php file.
<?php
if(isset($_POST['email']))
{
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "email#email.com";
$email_subject = "Subscription";
function died($error)
{
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if( !isset($_POST['email']))
{
died('We are sorry, but there appears to be a problem with the form you submitted.');      
}
$email_from = $_POST['email']; // required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from))
{
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
if(strlen($error_message) > 0)
{
died($error_message);
}
$email_message = "Form details below.\n\n";
function clean_string($string)
{
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "Email: ".clean_string($email_from)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
#mail($email_to, $email_subject, $email_message, $headers); 
?>
<!-- include your own success html here -->
Thank you for contacting us. We will be in touch with you very soon.
<?php
}
?>
That I found here, I just edited it a bit to fit my form. I'm really new to PHP and I'm still in the practice phase.
The error I get is
PHP Parse error: syntax error, unexpected T_VARIABLE in /home/techstars05/www/website/subscribe.php on line 6, referer: http://localhost/website/index.html
I'm using sublime text 2 to edit the codes and I noticed that "if(isset($_POST['email']))"'s 'if' is of a different color from the other ifs from the subscribe.php file. Its pink while the others are violet-ish. I'm not really sure what does mean, I tried tracing the code but to my newbie eyes it looks quite fine.
TIA

give this a try :
<?php
if(isset($_POST['email'])) {
//email is set
$email_from = $_POST['email'];
$email_exp = '/^[A-Za-z0-9._%-]+#[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(preg_match($email_exp,$email_from)) {
//email data
$email_from = $_POST['email'];
$email_to = "email#email.com";
$email_subject = "Subscription";
//create body
$email_message = "Form details below.\n\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
// create email headers
$headers = 'From: '.$email_from."\r\n".
$headers .= 'Reply-To: '.$email_from."\r\n" .
$headers .= 'X-Mailer: PHP/' . phpversion();
if(mail($email_to, $email_subject, $email_message, $headers)){
echo "email sent successfully";
exit();
}else{
echo "email failed to send";
}
}else{
echo "email is not valid";
}
}else{
echo "email is not set";
}
function clean_string($string){
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
?>
