自昨晚以来，我仅在我的index.php页面上一直收到此错误。我已经清除了所有cookie，但是仍然无法在本地主机上访问index.php。我已经看过其他解决方案，但找不到答案。
我认为这与我的index.php代码有关，该代码将我重定向到同一页面进行登录。但是我不熟悉Web开发，所以我不确定如何解决该问题。下面，我提供了我的index.php和login.php的代码段。非常感谢您的帮助。
login.php
<?php
session_start();
// Change this to your connection info.
$DB_HOST = 'localhost';
$DB_USER = 'root';
$DB_PASS = '';
$DB_NAME = 'ecom';
// Try and connect using the info above.
$con = mysqli_connect($DB_HOST, $DB_USER, $DB_PASS, $DB_NAME);
if ( mysqli_connect_errno() ) {
// If there is an error with the connection, stop the script and display the error.
die ('Failed to connect to MySQL: ' . mysqli_connect_error());
}
// Now we check if the data from the login form was submitted, isset() will check if the data exists.
if ( !isset($_POST['username'], $_POST['password']) ) {
// Could not get the data that should have been sent.
die ('Please fill both the username and password field!');
}
if ($stmt = $con->prepare('SELECT id, password FROM users WHERE username = ?')) {
// Bind parameters (s = string, i = int, b = blob, etc), in our case the username is a string so we use "s"
$stmt->bind_param('s', $_POST['username']);
$stmt->execute();
// Store the result so we can check if the account exists in the database.
$stmt->store_result();
}
if ($stmt->num_rows > 0) {
$stmt->bind_result($id, $password);
$stmt->fetch();
// Account exists, now we verify the password.
// password_hash function in is used in registration file to store the hashed passwords.
if (password_verify($_POST['password'], $password)) {
// Verification success! User has loggedin!
// Create sessions so we know the user is logged in, they basically act like cookies but remember the data on the server.
session_regenerate_id();
$_SESSION['loggedin'] = TRUE;
$_SESSION['name'] = $_POST['username'];
$_SESSION['id'] = $id;
/*echo 'Welcome ' . $_SESSION['name'] . '!';*/
header('Location: index.php');
} else {
echo 'Incorrect password!';
}
} else {
echo 'Incorrect username!';
}
$stmt->close();
?>
index.php
<?php
// We need to use sessions, so you should always start sessions using the below code.
session_start();
// If the user is not logged in redirect to the login page...
if (!isset($_SESSION['loggedin'])) {
header('Location:index.php');
exit();
}
?>

在index.php上 这部分代码。
if (!isset($_SESSION['loggedin'])) {
header('Location:index.php'); // redirecting to same page.
exit();
}
如果用户未登录，您将重定向到同一页面，这就是为什么您进行无限重定向...您必须重定向到其他页面（如登录页面）。
