DocumentationHackReferenceClassAsyncMysqlQueryResultstartTime

AsyncMysqlQueryResult::startTime

The start time when the successful query began, in seconds since epoch

public function startTime(): float;

Returns

float - the start time as float seconds since epoch.

Examples

Every successful query has a result. And one of the methods on an AsyncMysqlQueryResult is startTime(), which tells you the time when we started to get our result.

Note that

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

require __DIR__.'/../../__includes/async_mysql_connect.inc.php';

use \Hack\UserDocumentation\API\Examples\AsyncMysql\ConnectionInfo as CI;

async function connect(
  \AsyncMysqlConnectionPool $pool,
): Awaitable<\AsyncMysqlConnection> {
  return await $pool->connect(
    CI::$host,
    CI::$port,
    CI::$db,
    CI::$user,
    CI::$passwd,
  );
}
async function simple_query(): Awaitable<int> {
  $pool = new \AsyncMysqlConnectionPool(darray[]);
  $conn = await connect($pool);
  $result = await $conn->query('SELECT name FROM test_table WHERE userID = 1');
  // What time was it when we started to get this result?
  \var_dump($result->startTime());
  $conn->close();
  return $result->numRows();
}

function run(): void {
  $r = \HH\Asio\join(simple_query());
  \var_dump($r);
}

run();

Output

int(1)
