<?php
// 连接数据库
$host = "数据库主机名";
$username = "用户名";
$password = "密码";
$dbname = "数据库名称";
$conn = mysqli_connect($host, $username, $password, $dbname);

if (!$conn) {
    die("连接数据库失败: " . mysqli_connect_error());

// 执行查询
$query = "SELECT long_text_field FROM table_name";
$result = mysqli_query($conn, $query);

if (!$result) {
    die("查询失败: " . mysqli_error($conn));
}

// 获取结果并显示长文本
while ($row = mysqli_fetch_assoc($result)) {
    $longText = $row['long_text_field'];
    echo "<p>" . $longText . "</p>";
}

// 关闭数据库连接
mysqli_close($conn);
