Optimization

The process of recovering reviews can be quite long depending on the number of reviews to be recovered. A good strategy would be to temporarily save reviews in the db or cache, and retrieve them again only when needed.

Se utilizzi WordPress una buona strategia potrebbe essere sfruttare i transients.

Example

<?php

if ( false === ( $reviews = get_transient( 'trustpilot_reviews' ) ) ) {

  $scraper = new Trustpilot_Reviews('account_id', '-1', 'time', 'desc');
  $reviews = $scraper->get_reviews();
  set_transient( 'trustpilot_reviews', $reviews, 24 * HOUR_IN_SECONDS );
  
}

?>

In this case the reviews are saved in a transient with validity of 24 hours in the database. In this way, instead of performing the whole process of scraping and parsing, as long as the transient is valid, they are recovered directly from the database, and only when the transient expires they will be scraped again.
