In what ways can resolution or frequency of data collection be adjusted to optimize database storage in PHP?

To optimize database storage in PHP, resolution or frequency of data collection can be adjusted by reducing the amount of data stored or collected. This can be achieved by aggregating data over time periods, such as storing daily averages instead of raw data points. Additionally, implementing data retention policies to delete old or unnecessary data can help optimize database storage.

// Example of aggregating data over time periods to optimize database storage
$rawData = [10, 15, 20, 25, 30];
$average = array_sum($rawData) / count($rawData);

// Store the daily average instead of raw data points
// Insert $average into the database
