What are some best practices for integrating Google Maps with PHP forms?

When integrating Google Maps with PHP forms, it is important to ensure that the user's input is validated and sanitized before submitting to the Google Maps API. This helps prevent any potential security vulnerabilities or errors in the form submission process. Additionally, using proper error handling techniques can help provide a better user experience and troubleshoot any issues that may arise during the integration process. 

<?php

// Validate and sanitize user input
$address = isset($_POST['address']) ? htmlspecialchars($_POST['address']) : '';
$city = isset($_POST['city']) ? htmlspecialchars($_POST['city']) : '';
$state = isset($_POST['state']) ? htmlspecialchars($_POST['state']) : '';
$zip = isset($_POST['zip']) ? htmlspecialchars($_POST['zip']) : '';

// Form submission to Google Maps API
$api_key = 'YOUR_API_KEY';
$url = "https://maps.googleapis.com/maps/api/geocode/json?address=$address,$city,$state,$zip&key=$api_key";

$response = file_get_contents($url);
$data = json_decode($response, true);

// Handle errors
if ($data['status'] == 'OK') {
    $latitude = $data['results'][0]['geometry']['location']['lat'];
    $longitude = $data['results'][0]['geometry']['location']['lng'];
    echo "Latitude: $latitude, Longitude: $longitude";
} else {
    echo "Error: Unable to retrieve coordinates from Google Maps API";
}

?>
