mysql 怎么存储富文本格式

CREATE TABLE articles (
    id INT AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(255) NOT NULL,
    content LONGTEXT NOT NULL
);

$content = mysqli_real_escape_string($conn, $content);

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 准备富文本内容
$content = "<p>This is a <strong>rich text</strong> example.</p>";

// 转义特殊字符
$content = mysqli_real_escape_string($conn, $content);

// 插入数据
$sql = "INSERT INTO articles (title, content) VALUES ('Rich Text Example', '$content')";

if ($conn->query($sql) === TRUE) {
    echo "新记录插入成功";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
