Help Pulling map markers from database to display on map

Help Pulling map markers from database to display on map

greetings campers and leaders,

I am seeking advice regarding the following error when trying to pull lat long info from mysql database in order to display the markers on the map:

InvalidValueError: setPosition: not a LatLng or LatLngLiteral: not an Object

I believe this error means that the position key needs a value to be an object of some format, and its not happy with the format of the thing im passing it.

Steps I took to try to fix it:
I saw that latlng I was passing had () around it, so I used str_replace() to change that to {} I also saw that that what I was passing was missing the lat: and lng: so I added those as well, still not working…
I read this post on stackedoverflow and someone said to try to add in the parsefloat method, perhaps the numbers are not being interpreted as integers, but rather as strings… I did that, but its still not working.

If I hard code the values in , it seems to be working fine though.
All help appreciated.

Here is what Im seeing in my console:
console errors

	$stmt = $db->query('SELECT * FROM tbl_buildings');
	$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
	echo '<br/><br/>';
	foreach($results as $row) {
		//echo $row['name'].' '.$row['address']; //etc... 
		$latlong = str_replace('(', '{lat:parseFloat(' , $row['latlong']); //replace "(" with "{". "(lat,long)" will be "{lat,long)"
		echo $latlong."<br><br>";
		$latlong = str_replace(',','),lng:parseFloat(' , $latlong); //replace "," with ",lng:". "{lat: lat,lng:long)" will be "{lat,long}"
		echo $latlong."<br><br>";
		$pattern= '/\)$/';
		$replacement= ')}';
		$latlong= preg_replace($pattern, $replacement, $latlong);
		//$latlong = str_replace(')','}' , $latlong); //replace ")" with "}". "{lat: lat,lng: long)" will be "{lat: lat,lng:}"
		echo $latlong."<br><br>";

		$locations[] = array('name'=>$row['name'], 'latlong'=>$latlong);
	/* Convert data to json */         
	$markers = json_encode($locations);

          zoom: 13,

			<?php echo "var markers=$markers;\n"; ?>
			console.log('these are the markers '+markers);

		name = markers[x].name;
