Change JSON format php - php

Question

I have this php code that i need to change the JSON format i get the data from a mysql db:
// Retrieve data from database
$sql="SELECT nombre FROM deudores ORDER BY fecha ASC LIMIT 10";
$result=mysqli_query($con, $sql);
$emparray = array();
// Start looping rows in mysql database.
while($rows=mysqli_fetch_assoc($result)){
$emparray[] = $rows;
// close while loop
}
//print_r($emparray);
//echo json_encode($emparray);
$output = array(
'c2array' => true,
'size' => array(
0 => count($emparray),
1 => 1,
2 => 1
),
'data' => array()
);
$x = 0;
foreach ($emparray as $value) {
$output['data'][$x] = array();
$output['data'][$x][0] = array();
$output['data'][$x][0][0] = $value;
$x++;
}
echo json_encode($output);
That code print this JSON:
{"c2array":true,"size":[7,1,1],"data":[[[{"nombre":"test"}]],[[{"nombre":"Oscar"}]],[[{"nombre":"Oscar"}]],[[{"nombre":"test"}]],[[{"nombre":"test"}]],[[{"nombre":"oscar"}]],[[{"nombre":"Oscar"}]]]}
but i need the JSON to look like this:
{"c2array":true,"size":[7,1,1],"data":[[[test]],[[Oscar]],[[Oscar]],[[test]],[[test]],[[oscar]],[[Oscar]]]}
How can i achive this?
Thanks in advance!

Answer 1

Use mysql_fetch_row() instead of mysql_fetch_assoc.
while($rows=mysqli_fetch_row($result)){
$emparray[] = $rows;
// close while loop
}
And just set $emparray as value for $output['data']. No need extra work!
$output['data'] = $emparray;
This should make the output like this :
{"c2array":true,"size":[7,1,1],"data":[["test"],["Oscar"],["Oscar"],["test"],["test"],["oscar"],["Oscar"]]}
