AsyncMysqlQueryResult::vectorRows
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 string
s. 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>>
- AVector
ofVector
objects, where the outerVector
represents the rows and each innerVector
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.
