PHP-generated JSON for Google Maps: a tiny mystery - php

Question

I am using a PHP script (this one) to generate a JSON file for a Google Map.
this is the PHP code (note: I am using Laravel):
<?php
$query = "SELECT id, info, lat, lng FROM places";
$results = DB::select($query);
$myLocations = array();
$i = 0;
$testLoc = array('loc95' => array( 'lat' => 15, 'lng' => 144.9634 ));
foreach ($results as $result)
{
$myLocation = array(
'loc'.++$i => array(
'lat' => round((float)$result->lat, 4),
'lng' => round((float)$result->lng, 4)
));
$myLocations += $myLocation;
}
$myLocations += $testLoc;
echo json_encode($myLocations);
?>
and this is the output:
{"loc1":{"lat":45.4833,"lng":9.1854},"loc2":{"lat":45.4867,"lng":9.1648},"loc3":{"lat":45.4239,"lng":9.1652},"loc95":{"lat":15,"lng":144.9634}}
ok. the script I use to put the JSON data in a Google Map, unfortunately, keeps ignoring any data coming from the MySQL database, and shows only the test data place(s). I have tried to swap data, to put in test data the same info found in database... nothing, I keep seeing only the test data.
but, really: I cannot figure out why. What am I missing... ?

Answer 1

You wrote that you're using another script and that the other script only shows the testlocations on google maps.
My guess is that you didn't update the other script to your needs, specifically my crystal ball is telling me that you still have this line in there:
setMarkers(locs);//Create markers from the initial dataset served with the document.
In your question you only showed the part which worked and I agree, but you only mentioned that "something else" isn't working. If you want an answer for that part, try reprashing your question and include the parts which cause you problems.
