How can the LatLng-Markierung option in Google Maps Labs be utilized effectively in a PHP project?

Issue: To utilize the LatLng-Markierung option in Google Maps Labs effectively in a PHP project, you can use the Google Maps JavaScript API to create a map with custom markers at specific latitude and longitude coordinates.

<?php
// Define latitude and longitude coordinates
$lat = 37.7749;
$lng = -122.4194;

// Create a Google Maps map with custom marker at the specified coordinates
echo '<div id="map" style="height: 400px;"></div>';
echo '<script>
function initMap() {
  var map = new google.maps.Map(document.getElementById("map"), {
    zoom: 12,
    center: {lat: ' . $lat . ', lng: ' . $lng . '}
  });
  
  var marker = new google.maps.Marker({
    position: {lat: ' . $lat . ', lng: ' . $lng . '},
    map: map,
    title: "Marker Title"
  });
}
</script>';
echo '<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"></script>';
?>
