What are the best practices for editing database entries in PHP?

When editing database entries in PHP, it is important to sanitize user input to prevent SQL injection attacks. It is also recommended to use prepared statements to safely interact with the database and avoid exposing sensitive information. Additionally, always validate user input to ensure it meets the required format and constraints before updating the database. 

// Example of editing database entries in PHP

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

// Prepare the SQL statement
$stmt = $pdo->prepare("UPDATE table_name SET column_name = :edited_value WHERE id = :id");

// Bind parameters
$stmt->bindParam(':edited_value', $editedValue);
$stmt->bindParam(':id', $_POST['id']);

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