What are the best practices for using call_user_func_array in PHP to ensure efficient and effective code execution?

When using call_user_func_array in PHP, it is important to ensure efficient and effective code execution by passing the function name as a string and the arguments as an array. This allows for dynamic function calls and can help streamline code logic. Additionally, using call_user_func_array can be particularly useful when dealing with variable numbers of arguments or when working with callback functions. 

// Example of using call_user_func_array to efficiently execute a function with dynamic arguments
function myFunction($arg1, $arg2) {
    return $arg1 + $arg2;
}

$functionName = 'myFunction';
$arguments = [10, 20];

$result = call_user_func_array($functionName, $arguments);
echo $result; // Output: 30
