Are there any best practices for efficiently managing connection counts in a PHP application?

Managing connection counts in a PHP application is crucial for optimizing performance and preventing resource exhaustion. One best practice is to use connection pooling to reuse existing connections instead of creating new ones for each request. This can help reduce the overhead of establishing new connections and improve overall efficiency. 

// Implementing connection pooling in PHP using PDO
$pdo = null;

function getConnection() {
    global $pdo;
    
    if ($pdo == null) {
        $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
    }
    
    return $pdo;
}

// Example usage
$connection = getConnection();
// Use $connection for database operations
