PHP代码停止下面的代码[重复]

I have this PHP code:

<?php
$redirectURL = 'contests-representative-of-the-year-thankyou.php';
$email_to = 'alex@theadamgrp.com';
$subject = 'Submission Form';
#### DO NOT EDIT BELOW THIS LINE ####
require_once dirname(__FILE__) . '/securimage.php';
$securimage = new Securimage();
$captcha = (isset($_REQUEST['ct_captcha'])) ? $_REQUEST['ct_captcha'] :
'';

if ($securimage->check($captcha) == false)   {
    die ('<p style="margin:30px 0 0 0; font-weight:bold; font-size:16px;">Invalid security code entered. Please <a href="javascript:history.go(-1);">click here</a> to go back.</p>');
}

$message = 'This form submission was received at '.date('n/j/Y g:i A').': '."

";
foreach ($_POST as $key=>$value){
    $message .= "

".str_replace('_', ' ', $key).": 
".$value;
}

$message .= "

IP: ".$_SERVER['REMOTE_ADDR'];
mail($email_to, $subject, $message, 'From: no-reply@email.com');
?>

When I insert this into my web page, it "deletes" the rest of my code below. I'm suppose to have a footer below it with links and everything. This is what I have below it:

</div>
</div>
<?php include("subpage-bar.php"); ?>
</div>
</div>
</div>
<?php include("footer.php"); ?>
</body>

Is there any reason why my PHP code above would delete everything else I have coded below it? Here is a link to view the source, if you want to visually see what O mean. I can't figure out what the problem is. Any help is appreciated.

</div>

change die() into echo

So change

die ('<p style="margin:30px 0 0 0; font-weight:bold; font-size:16px;">Invalid security code entered. Please <a href="javascript:history.go(-1);">click here</a> to go back.</p>');

into

echo '<p style="margin:30px 0 0 0; font-weight:bold; font-size:16px;">Invalid security code entered. Please <a href="javascript:history.go(-1);">click here</a> to go back.</p>';

(so echo without the parens ())

edit

For the working catha change this:

if ($securimage->check($captcha) == false)   {
    die ('<p style="margin:30px 0 0 0; font-weight:bold; font-size:16px;">Invalid security code entered. Please <a href="javascript:history.go(-1);">click here</a> to go back.</p>');
}

$message = 'This form submission was received at '.date('n/j/Y g:i A').': '."

";
foreach ($_POST as $key=>$value){
    $message .= "

".str_replace('_', ' ', $key).": 
".$value;
}

$message .= "

IP: ".$_SERVER['REMOTE_ADDR'];
mail($email_to, $subject, $message, 'From: no-reply@email.com');

into this:

if ($securimage->check($captcha) == false)   {
    echo '<p style="margin:30px 0 0 0; font-weight:bold; font-size:16px;">Invalid security code entered. Please <a href="javascript:history.go(-1);">click here</a> to go back.</p>';
} else {
    $message = 'This form submission was received at '.date('n/j/Y g:i A').': '."

";
    foreach ($_POST as $key=>$value){
        $message .= "

".str_replace('_', ' ', $key).": 
".$value;
    }

    $message .= "

IP: ".$_SERVER['REMOTE_ADDR'];
    mail($email_to, $subject, $message, 'From: no-reply@email.com');
}
