Are there any best practices for managing MySQL database connections in PHP when working with stored procedures?

When working with stored procedures in MySQL database connections in PHP, it is important to properly manage the connections to ensure efficiency and avoid potential issues such as connection leaks. One best practice is to use a connection pool to reuse connections instead of creating new ones for each stored procedure call. 

// Create a connection pool using PDO
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

// Function to execute stored procedure using a connection from the pool
function executeStoredProcedure($pdo, $procedureName, $params) {
    $stmt = $pdo->prepare("CALL $procedureName(?)");
    $stmt->execute([$params]);
    
    // Process the results or return as needed
    $results = $stmt->fetchAll(PDO::FETCH_ASSOC);
    
    return $results;
}

// Example of calling the stored procedure using the connection pool
$results = executeStoredProcedure($pdo, 'my_stored_procedure', 'param_value');
print_r($results);
