如何在php中打印包含特殊字符的列的内容

<?php
// 连接到数据库
$servername = "数据库主机名";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名称";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// 执行查询
$sql = "SELECT special_column FROM your_table";
$result = $conn->query($sql);

// 获取结果并打印内容
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $specialContent = htmlspecialchars($row["special_column"]);
        echo $specialContent . "<br>";
    }
} else {
    echo "没有结果";
}

// 关闭数据库连接
$conn->close();
?>
