What are the common pitfalls when trying to save HTML-encoded text in a MySQL database with PHP?

When saving HTML-encoded text in a MySQL database with PHP, common pitfalls include not properly escaping the data before insertion to prevent SQL injection attacks, and not handling special characters that are part of HTML encoding. To solve this issue, you should use prepared statements with parameterized queries to safely insert HTML-encoded text into the database. 

// Assume $htmlEncodedText contains the HTML-encoded text to be saved

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare("INSERT INTO your_table (html_text) VALUES (:htmlEncodedText)");

// Bind the HTML-encoded text to the parameter
$stmt->bindParam(':htmlEncodedText', $htmlEncodedText);

// Execute the query
$stmt->execute();
