What are the common issues with storing HTML in a database using PHP?

One common issue with storing HTML in a database using PHP is that special characters in the HTML code can interfere with the database query, causing errors or unexpected behavior. To solve this issue, you can use PHP's `mysqli_real_escape_string()` function to properly escape the HTML content before inserting it into the database. 

// Assuming $html contains the HTML content to be stored in the database

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Escape the HTML content
$escaped_html = $mysqli->real_escape_string($html);

// Insert the escaped HTML content into the database
$query = "INSERT INTO table_name (html_content) VALUES ('$escaped_html')";
$mysqli->query($query);

// Close the database connection
$mysqli->close();
