mySQL to JSON Object仅返回第一行

Question

these lines of code :

$sql ="SELECT * FROM parcours";
$r = mysqli_query($con,$sql);
$result = array();

while($res = mysqli_fetch_array($r)){

 $result[] = $res;
}
echo json_encode(array("result"=>$result));

returns me only the first row of my DB request.

How can I get all of it ?

Answer 1

I think you need to use mysqli_fetch_assoc :

while($res = mysqli_fetch_assoc($r)){

 $result[] = $res;
}

and then :

echo json_encode(array($result));
