第 6 行的 PHP 解析错误......似乎这是我忽略的简单事情。

Question

我在创建简单的登录表单时遇到问题。谁能解释为什么SQL在第6行说"解析错误：语法错误，C：\xampp\htdocs\Easy Grade 2000\login.php中意外的'$username'（T_VARIABLE）"以及如何修复它？

谢谢

<?php
include 'connect.php'
// username and password sent from form 
$username = $_POST['u_name']; 
$password = $_POST['p_word']; 
$sql="SELECT * FROM $db_name WHERE u_name='$username' and p_word='$password'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword"); 
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>

您忘记了包含以下内容后面的分号：

include 'connect.php';
