json_encode multiple arrays into one JSON object in PHP? - php

Question

I'm new to php and am trying to encode 2 arrays together into one JSON object.
Currently this is the JSON output:
{
"image_link": "some url",
"zoomin_level": "8",
"zoomout_level": "18.5",
"position_lat": "32.913105",
"position_long": "-117.140363",
}
What I like to achieve is the following:
{
"image_link": "some url",
"zoomin_level": "2",
"zoomout_level": "15",
"position_lat": "32.9212",
"position_long": "-117.124",
"locations": {
"1": {
"image_link": "some url",
"name": "Name",
"lat": 32.222,
"marker_long": -112.222
},
"2": {
"image_link": "some url",
"name": "Name",
"lat": 32.222,
"marker_long": -112.222
}
}
}
This is similar to the question asked here: PHP json_encode multiple arrays into one object
However mine is a bit different because I like to add the 2nd array as part of a key-value part within the 1st array.
Here's my php code:
$sql = "select * from first_table";
$result = mysqli_query($connection, $sql) or die("Error in Selecting " . mysqli_error($connection));
$rowCount = $result->num_rows;
$index = 1 ;
$newArray = [];
while($row =mysqli_fetch_assoc($result))
{
$sqlnew = "select * from second_table";
$resultnew = mysqli_query($connection, $sqlnew) or die("Error in Selecting " . mysqli_error($connection));
//create an array
$jsonData = array();
$rowCountnew = $resultnew->num_rows;
$indexnew = 1;
if ($rowCountnew >0)
{
while($rownew =mysqli_fetch_assoc($resultnew))
{
$locations[$indexnew] = array("image_link" => $rownew['image_link'], "name" => $rownew['name'], "position_lat" => doubleval($rownew['position_lat']), "position_long" => doubleval($rownew['position_long']) );
++$indexnew;
}
}
$newArray[$row['map_type']] = $row['map_value'];
}
echo json_encode($newArray);
Not knowing the proper syntax, I tried to perform the following which resulted in garbage: echo json_encode($newArray, "locations" =>$locations);

Answer 1

Try:
$newArray['locations'] = $locations;
echo json_encode ($newArray);
