DocumentationHackReferenceClassAsyncMysqlQueryResultelapsedMicros

AsyncMysqlQueryResult::elapsedMicros

The total time for the successful query to occur, in microseconds

public function elapsedMicros(): int;

Returns

int - the total successful result producing time as int microseconds.

Examples

Every successful query has a result. And one of the methods on an AsyncMysqlQueryResult is elapsedMicros(), which tells you how long it took to perform the query and get the result.

Note that

  elapsedMicros() ~== endTime() - startTime()
