lastActivityTime

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Last time a successful activity was made in the current connection, in seconds since epoch

public function lastActivityTime(): float;

The first successful activity of the current connection is its creation.

Returns

• float - A float representing the number of seconds ago since epoch that we had successful activity on the current connection.

Examples

This example shows how to determine the last time a successful call was made using a given connection via AsyncMysqlConnection::lastActivityTime. The value returned is seconds since epoch as a float.

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 get_time(): Awaitable<float> {
  $pool = new \AsyncMysqlConnectionPool(darray[]);
  $conn = await connect($pool);
  $t = $conn->lastActivityTime();
  $conn->close();
  return $t;
}

<<__EntryPoint>>
async function run(): Awaitable<void> {
  $t = await get_time();
  \var_dump($t);
}
