Get multidimensional array out of query - php

Question

I am trying to get multidimensional array out of query and for some reasons it does not work.
I use query to retrieve data from mysql.
$sql = "SELECT Id, UserID, TimeAction, Command FROM users_checked WHERE UserId = 4 AND date(TimeAction) = '2016-12-05 '";
$q=$conn->query($sql);
$data = array();
while($r=$q->fetchAll((PDO::FETCH_ASSOC))){
$data[]=$r;
}
Array output
I should get array like printed below
$data = array(
array(
"Id" => "1",
"UserID" => "1",
"TimeAction" => "2016-11-29 08:00:00",
"Command" => "Prijava"
),
array(
"ID" => "1",
"USERID" => "1",
"TimeAction" => "2016-11-29 10:05:14",
"Command" => "Odjava"
),
array(
"Id" => "1",
"UserID" => "1",
"TimeAction" => "2016-11-29 12:22:14",
"Command" => "PoslovniIzlazak"
),
array(
"ID" => "1",
"USERID" => "1",
"TimeAction" => "2016-11-29 13:32:14",
"Command" => "Prijava"
),
array(
"ID" => "1",
"USERID" => "1",
"TimeAction" => "2016-11-29 16:00:00",
"Command" => "Odjava"
),
);

Answer 1

fetchAll - Returns an array containing all of the result set rows where as fetch - Fetches the next row from a result set.
So you have to use fetch instead of fetchAll if you want the data row wise.
Try this code.
while ($r = $q->fetch(PDO::FETCH_ASSOC))
{
$data[] = $r;
}
Reference:
fetch
fetchAll

Answer 2

You should probably use fetch_assoc() instead of fetch_all in your for loop, this way you can push the data you want into your array for each row of your mysql query result.
It would look like this :
$data = array();
while ($row = $r->fetch_assoc()) {
$row_array = array(
"Id" => row['Id'],
"UsedID" => row['UserID'],
"TimeAction" => row['TimeAction'],
"Command" => row['Command']
);
array_push($data, $row_array);
}
Please note I didn't test the code, I'm doing this by head.
Also, I'm guessing you didn't mean to write all Ids to "1" in your example.
