vectorRows

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.

Returns the actual rows returned by the successful query, each row including the values for each column

public function vectorRows(): Vector<KeyedContainer<int, ?string>>;

All values come back as strings. If you want typed values, use vectorRowsTyped().

The rows are returned as a Vector of Vector objects which hold the (possibly null) string values of each column in the order of the original query.

Returns

• Vector<KeyedContainer<int,?string>> - A Vector of Vector objects, where the outer Vector represents the rows and each inner Vector represent the column values for each row.

Examples

When executing a query, you can get the rows returned from it in the form of a Vector of Vector objects, where each value of the Vector is a column value. This example shows how to use AsyncMysqlQueryResult::vectorRows to get that Vector. A resulting Vector may look like:

object(HH\Vector)#9 (2) {
  [0]=>
  object(HH\Vector)#10 (1) {
    [0]=>
    string(11) "Joel Marcey"
  }
  [1]=>
  object(HH\Vector)#11 (1) {
    [0]=>
    string(11) "Fred Emmott"
  }
}

Note that all values in the Vector returned from vectorRows will be string or null. If you want specifically-typed values, use vectorRowsTyped.

Also understand that if you want the actual column names associated with the values in the Vector, you should use mapRows instead.
