使用php显示包含来自数据库的html标签的内容

Table name : Post, column name : content say, below data along with the html tag and style is stored in content column

<h1 style="color:red">test</h1>

I'm using below php code to display it

<?php
$sql = "SELECT content FROM post where id = 1";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
    // output data of each row
  while($row = $result->fetch_assoc()) {

    ?>
    <?php echo htmlspecialchars($row['content'], ENT_QUOTES); ?>
    <?php
  }
}
else {
echo "0 rasdesults";
}
$conn->close();
?>

expectation : test in red color but output : only "test"
