How can PHP developers optimize their code to efficiently count occurrences of a specific name in a database query?

To efficiently count occurrences of a specific name in a database query, PHP developers can utilize the SQL COUNT function along with a WHERE clause to filter results based on the specific name. This approach allows for the database to handle the counting operation, reducing the amount of data transferred to the PHP script and improving performance. 

<?php
// Assuming $db is your database connection
$name = 'John Doe';
$query = "SELECT COUNT(*) as count FROM table_name WHERE name = :name";
$statement = $db->prepare($query);
$statement->bindParam(':name', $name);
$statement->execute();
$result = $statement->fetch(PDO::FETCH_ASSOC);
$count = $result['count'];
echo "Occurrences of $name: $count";
?>
