What are the differences between PHP and JavaScript in terms of coding for Google Maps integration?

When integrating Google Maps into a website, PHP is typically used for server-side tasks like fetching data from a database, while JavaScript is used for client-side tasks like displaying the map and handling user interactions. PHP can be used to generate dynamic content for the map, such as markers or info windows, while JavaScript is used to actually render and interact with the map on the front end. 

<?php
// PHP code to retrieve location data from a database
$locations = array(
    array('lat' => 37.7749, 'lng' => -122.4194, 'name' => 'San Francisco'),
    array('lat' => 34.0522, 'lng' => -118.2437, 'name' => 'Los Angeles'),
    // Add more locations as needed
);

// Convert PHP array to JSON for JavaScript
$locations_json = json_encode($locations);
?>

<script>
// JavaScript code to initialize Google Map with PHP-generated data
var locations = <?php echo $locations_json; ?>;
var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 4,
    center: {lat: 37.0902, lng: -95.7129}
});

locations.forEach(function(location) {
    var marker = new google.maps.Marker({
        position: {lat: location.lat, lng: location.lng},
        map: map,
        title: location.name
    });
});
</script>
