Class Phalcon\Db\Profiler

Source on GitHub

Instances of Phalcon\Db can generate execution profiles on SQL statements sent to the relational database. Profiled information includes execution time in milliseconds. This helps you to identify bottlenecks in your applications.

  1. <?php
  3. $profiler = new \Phalcon\Db\Profiler();
  5. // Set the connection profiler
  6. $connection->setProfiler($profiler);
  8. $sql = "SELECT buyer_name, quantity, product_name
  9. FROM buyers LEFT JOIN products ON
  10. buyers.pid=products.id";
  12. // Execute a SQL statement
  13. $connection->query($sql);
  15. // Get the last profile in the profiler
  16. $profile = $profiler->getLastProfile();
  18. echo "SQL Statement: ", $profile->getSQLStatement(), "\n";
  19. echo "Start Time: ", $profile->getInitialTime(), "\n";
  20. echo "Final Time: ", $profile->getFinalTime(), "\n";
  21. echo "Total Elapsed Time: ", $profile->getTotalElapsedSeconds(), "\n";
