How can SQL queries be optimized to accurately count the number of articles in a specific category in PHP?

To accurately count the number of articles in a specific category in PHP, you can optimize your SQL query by using the COUNT function along with a WHERE clause to filter by the desired category. This will efficiently retrieve the count of articles in that specific category. 

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

// Define the category you want to count articles for
$category = 'technology';

// Prepare SQL query to count articles in the specified category
$sql = "SELECT COUNT(*) FROM articles WHERE category = :category";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':category', $category);
$stmt->execute();

// Fetch the count of articles in the specified category
$count = $stmt->fetchColumn();

echo "Number of articles in category $category: $count";
