Bug description:mysqli_result::fetch_all returns null, not an empty array
Description:
------------
The documentation says that mysqli_result::fetch_all
- "fetches all result rows and returns the result set as an associative
array, a numeric array, or both"
- "Returns an array of associative or numeric arrays holding result rows"
(though the return type is "mixed").
As far as I can tell, fetch_all returns NULL when there are no rows (ie,
->num_rows==0).
Filed as a bug and not a documentation problem because it'd be nice to
always get an array back.
Test script:
---------------
// Requires that mysqlnd be loaded, of course
// $mysqli = new mysqli(...)
$result = $mysqli->query("SELECT 1 LIMIT 0");
var_dump($result->fetch_all());
Expected result:
----------------
array(0) {
}
Actual result:
--------------
NULL
