How can the code be optimized to ensure that all values are combined with $start_date, $end_date, $google_analytics_metrics, $params in the foreach loop?

To ensure that all values are combined with $start_date, $end_date, $google_analytics_metrics, $params in the foreach loop, you can create an array that contains these values and then iterate over that array in the foreach loop. This way, each iteration will have access to all the necessary values. 

// Array containing all necessary values
$data = [
    'start_date' => $start_date,
    'end_date' => $end_date,
    'google_analytics_metrics' => $google_analytics_metrics,
    'params' => $params
];

// Iterate over the data array
foreach ($data as $key => $value) {
    echo "$key: $value\n";
    // Perform operations using $key and $value
}
