What are best practices for handling data manipulation and database interaction in PHP, specifically when working with external APIs and WordPress integration?

When handling data manipulation and database interaction in PHP, especially when working with external APIs and WordPress integration, it is important to sanitize user input to prevent SQL injection attacks and validate data before inserting it into the database. Additionally, use prepared statements to securely interact with the database and handle errors gracefully to provide informative feedback to users. 

// Example of sanitizing user input and using prepared statements in PHP

// Sanitize user input
$user_input = $_POST['user_input'];
$sanitized_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Prepare a SQL statement with a prepared statement
$stmt = $pdo->prepare("INSERT INTO table_name (column_name) VALUES (:input)");
$stmt->bindParam(':input', $sanitized_input, PDO::PARAM_STR);

// Execute the prepared statement
$stmt->execute();

// Check for errors and provide feedback to the user
if($stmt->errorCode() == 0){
    echo "Data inserted successfully";
} else {
    $error_info = $stmt->errorInfo();
    echo "Error: " . $error_info[2];
}
