我的PHP文档说它有一个意想不到的结局

<?php
require('config.php');

if(isset($_post['submit'])){

//Perform Verification
$email1 = $_POST['email1'];
$email2 = $_POST['email2'];

if($email1 == email2) {
    $firstName = mysql_escape_string($_POST['firstName']);
    $lastName = mysql_escape_string($_POST['lastName']);
    $username = mysql_escape_string($_POST['username']);
    $email1 = mysql_escape_string($email1);
    $email2 = mysql_escape_string($email2);
    $phone = mysql_escape_string($_POST['phone']);


    $sql = mysql_query("SELECT * FROM `websiteAccount` WHERE `username`           = '$username'");
    if(mysql_num_rows($sql) > 0) {
    echo "Sorry, that usename is already in use.";
        exit();
    }

    mysql_query("INSERT INTO `websiteAccount` (`id`, `firstName`,   `lastName`, `username` `email`, `phone`) VALUES (NULL, '$firstName', '$lastName', '$username', '$email1', '$phone')");


 }else{ 
    echo "Emails do not match";
 }
     }else{
 $form = <<<EOT

When I tried to open this code in my PHP Server: I received a message saying Parse error: syntax error, unexpected end of file in /Applications/XAMPP/xamppfiles/htdocs/Web/register.php on line 48

Warning

It is very important to note that the line with the closing identifier must contain no other characters, except a semicolon (;).

You need to remove this extra space.
