What are best practices for dynamically constructing and executing SQL queries for multiple entries in PHP?

When dynamically constructing and executing SQL queries for multiple entries in PHP, it is important to use prepared statements to prevent SQL injection attacks and improve performance. By using placeholders in the query and binding the values separately, you can safely execute the query with different values for each entry. 

// Sample code to dynamically construct and execute SQL queries for multiple entries

// Assuming $entries is an array of entries to be inserted
$entries = [
    ['John', 'Doe'],
    ['Jane', 'Smith'],
    ['Alice', 'Johnson']
];

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare the SQL query with placeholders
$stmt = $pdo->prepare("INSERT INTO users (first_name, last_name) VALUES (?, ?)");

// Loop through each entry and execute the query with the values
foreach ($entries as $entry) {
    $stmt->execute($entry);
}
