php - How to get single column values using MySQLi?

Question

I am trying to get list or emails in a one-dimensional array from MySQL database. However, I am getting multidimensional array, rather then array:

$query = "SELECT DISTINCT `EmailAddress` FROM `Emails` WHERE `JobID` = 1";
$result = $conn->query($query);
if (!$result) {
    printf("Query failed: %s
", $mysqli->error);
    exit;
}
while ($row = $result->fetch_row()) {
    $rows[] = $row;
}
$result->close();
$conn->close();
var_dump($rows); // This will return array(2) { [0]=> array(1) { [0]=> string(24) "[email protected]" } [1]=> array(1) { [0]=> string(17) "[email protected]" } }
//This is how array should be
$MyV = array("[email protected]", "[email protected]");
var_dump($MyV); //this is an array I need to have: array(2) { [0]=> string(11) "[email protected]" [1]=> string(11) "[email protected]" }

Answer 1

do fetch_assoc

while($row = $result->fetch_assoc()) {
  $rows[]=$row['EmailAddress'];
}
