AsyncMysqlQueryResult::mapRowsTyped
Returns the actual rows returned by the successful query, each row including the name and typed-value for each column
public function mapRowsTyped(): Vector<Map<string, mixed>>;
The rows are returned as a Vector
of Map
objects. The Map
objects map
column names to (possibly null
) mixed
values (e.g., an INTEGER
column
will come back as an int
.)
Returns
Vector<Map<string,
mixed>>
- AVector
ofMap
objects, where theVector
elements are the rows and theMap
elements are the column names and typed values associated with that row.
Examples
When executing a query, you can get the rows returned from it in the form of a Vector
of Map
objects, where each key of the Map
is a column name. This example shows how to use AsyncMysqlQueryResult::mapRowsTyped
to get that Map
. A resulting Map
may look like:
object(HH\Vector)#9 (2) {
[0]=>
object(HH\Map)#10 (2) {
["name"]=>
string(11) "Joel Marcey"
["age"]=>
int(41)
}
[1]=>
object(HH\Map)#11 (2) {
["name"]=>
string(11) "Fred Emmott"
["age"]=>
int(26)
}
}
Note that all values in the Map
returned from mapRowsTyped
will be the actual typed representation of the database type, or null
. Above you can see we have string
and int
. If you want just string
values for everything, use mapRows
