How can PHP developers avoid issues with special characters like '|' when storing chat messages in a database?

Special characters like '|' can cause issues when storing chat messages in a database if not properly handled. To avoid this problem, PHP developers can use prepared statements or parameterized queries when inserting data into the database. This approach automatically escapes special characters, preventing SQL injection attacks and ensuring that the data is stored correctly. 

// Using prepared statements to insert chat messages into the database
$stmt = $pdo->prepare("INSERT INTO chat_messages (message) VALUES (:message)");
$stmt->bindParam(':message', $message);
$message = "This is a chat message with | special character";
$stmt->execute();
