What best practices should be followed when integrating weather data from Google API in PHP?

When integrating weather data from Google API in PHP, it is important to follow best practices to ensure smooth functionality and data accuracy. One key practice is to securely store your API key and never expose it in your code. Additionally, make sure to handle errors and exceptions properly to prevent any disruptions in the application flow. Lastly, consider caching the weather data to reduce the number of API calls and improve performance.

<?php

// Store your Google API key securely
$api_key = 'YOUR_API_KEY_HERE';

// Make a request to the Google Weather API
$city = 'New York';
$url = "https://maps.googleapis.com/maps/api/geocode/json?address=$city&key=$api_key";
$response = file_get_contents($url);

// Handle errors and exceptions
if ($response === false) {
    die('Error fetching data from Google API');
}

// Decode the JSON response
$data = json_decode($response, true);

// Cache the weather data
$weather_data = $data['results'][0]['weather'][0];
echo $weather_data;

?>
