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.
$profiler = new \Phalcon\Db\Profiler(); //Set the connection profiler $connection->setProfiler($profiler); $sql = "SELECT buyer_name, quantity, product_name FROM buyers LEFT JOIN products ON buyers.pid=products.id"; //Execute a SQL statement $connection->query($sql); //Get the last profile in the profiler $profile = $profiler->getLastProfile(); echo "SQL Statement: ", $profile->getSQLStatement(), "\n"; echo "Start Time: ", $profile->getInitialTime(), "\n"; echo "Final Time: ", $profile->getFinalTime(), "\n"; echo "Total Elapsed Time: ", $profile->getTotalElapsedSeconds(), "\n";
