How can PHP developers ensure the reusability of placeholders in PDO Prepared Statements?

To ensure the reusability of placeholders in PDO Prepared Statements, PHP developers can create an array to store the values of the placeholders and bind them dynamically in a loop when executing the statement. This allows for the same prepared statement to be reused with different values without the need to recreate the statement each time. 

// Sample code snippet to demonstrate reusability of placeholders in PDO Prepared Statements

// Sample array of values to bind to the placeholders
$values = array('John Doe', 'john.doe@example.com', 25);

// Sample PDO connection
$pdo = new PDO('mysql:host=localhost;dbname=test', 'username', 'password');

// Sample prepared statement with placeholders
$stmt = $pdo->prepare("INSERT INTO users (name, email, age) VALUES (?, ?, ?)");

// Loop through the array of values and bind them to the placeholders
foreach ($values as $key => $value) {
    $stmt->bindValue($key + 1, $value);
}

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