标头（）；无法正常工作

Question

在标记此重复或标记之前，请注意我在网上找到的解决方案都没有解决我的问题。所以我试图在上传所有内容后将人们重定向到 /home.php。

<?php
    session_start();
    ini_set('display_errors',1);
    error_reporting(E_ALL | E_WARNING | E_NOTICE);
    include('head.php');
    $title = $_POST['title'];
    $title = stripslashes($title);
    $title = mysqli_real_escape_string($conn, $title);
    $preview = $_POST['preview'];
    $preview = stripslashes($preview);
    $preview = mysqli_real_escape_string($conn, $preview);
    $thumbnail = $_POST['thumbnail'];
    $thumbnail = stripslashes($thumbnail);
    $thumbnail = mysqli_real_escape_string($conn, $thumbnail);
    $category = $_POST['category'];
    $category = stripslashes($category);
    $category = mysqli_real_escape_string($conn, $category);
    $content = $_POST['content'];
    $content = stripslashes($content);
    $content = mysqli_real_escape_string($conn, $content);
    $content = str_replace('\r', '', $content);
    $content = str_replace('\n', '</p><p>', $content);
    $content = str_replace('</p><p> </p><p>', '</p><p>', $content);
    $content = str_replace('</p><p></p><p>', '</p><p>', $content);
    $content = str_replace('</p><p>\r\n</p><p>', '</p><p>', $content);
    $content = str_replace(' i ', ' I ', $content);
    //To capitalize I's.
    $author = $_SESSION['id'];

    if ($_SESSION['rank'] == 2) {
        $status = 1;
    }
    else {
        $status = 0;
    }

    $sql = mysqli_query($conn, "INSERT INTO article (title, preview, author, thumbnail, section, content, status) VALUES ('$title', '$preview', '$author', '$thumbnail','$category', '$content', $status)");
    if ($sql == true) {
        $section = strtolower($category);
        print $section;
        flush();
        header('location:/home.php');
    }
    else {
        print "Did not work.";
    }
?>
<style>
html {background: #FFFFFF;}
</style>

我知道这与 html 部分无关，因为在我添加之前代码无法正常工作。我已打开所有错误报告，所以我不知道我的代码有什么问题。

尝试在重定向下方添加exit;。

header('location:/home.php');
exit;
