最后一行的PHP语法错误？

Question

<?php
if (!isset($_POST['ign'], $_POST['email'])) {
    if($_POST['ign'] && $_POST['email']){
    echo "Please fill out all of the fields!";
        die;
}

if (empty($_POST['ign']) || empty($_POST['email'])) { 
    echo ("Please enter all of the values!"); 
    die;
}

if(filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
    $email = $_POST['email'];
    echo ("Thanks, " . htmlentities($_POST['ign']) . ", you will recieve an email when the site is complete!");

}

else {
    echo "Your email was invalid!";
    die;
}
?>

我在最后一行收到语法错误,其中？>是..

另外,只是一个随机的旁注,任何人都可以教我如何将其插入我的代码？

$valid = (bool)preg_match('/^[a-zA-Z0-9]{1,30}$/', $_POST['username']);

它只是

if ($valid == TRUE) {
////////
}

或者声明变量已经运行了吗？
