What are some best practices for dynamically inserting database values into PHP code?

When dynamically inserting database values into PHP code, it is important to use prepared statements to prevent SQL injection attacks and ensure data integrity. This involves using placeholders in the SQL query and binding the actual values to these placeholders before executing the query. 

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

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");

// Bind the actual values to the placeholders
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

// Set the values of $value1 and $value2
$value1 = "some value";
$value2 = "another value";

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