How can PHP be optimized for counting tables in a database to improve performance and efficiency?

To optimize PHP for counting tables in a database, we can use a more efficient query that directly retrieves the count of tables from the database system. This can improve performance and efficiency by reducing the amount of data transferred between the PHP script and the database. 

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

// Query to count tables in the database
$sql = "SELECT COUNT(*) as table_count FROM information_schema.tables WHERE table_schema = 'mydatabase'";

// Execute the query
$stmt = $pdo->query($sql);
$result = $stmt->fetch(PDO::FETCH_ASSOC);

// Output the table count
echo "Number of tables in the database: " . $result['table_count'];
?>
