Project Description

This project provides a weather forecast application that fetches and displays the current weather and a 5-day forecast based on the user's location. The application uses the OpenWeatherMap API to retrieve weather data and displays it in a user-friendly format.

Files Overview

get_weather.php

This PHP script is responsible for fetching weather data based on the latitude and longitude provided as query parameters. It performs the following tasks:

• Retrieves the latitude and longitude from the query parameters.
• Uses the OpenWeatherMap API to fetch the current weather and 5-day forecast data.
• Processes the forecast data to calculate daily averages.
• Returns the weather data and forecast in JSON format.

index.php

This PHP file serves as the main entry point for the application. It performs the following tasks:

• Prevents caching of the page to ensure fresh data is always fetched.
• Retrieves the visitor's IP address and logs it to a file (ip_log.txt).
• Uses the IP address to fetch location information (latitude, longitude, and timezone) from an external service (ipinfo.io).
• Uses the latitude and longitude to fetch the current weather and 5-day forecast data from the OpenWeatherMap API.
• Processes the forecast data to calculate daily averages and formats it for display.
• Contains the HTML structure and JavaScript to display the weather data on the webpage.
• Uses geolocation to fetch weather data based on the user's current location if available, otherwise falls back to IP-based location data.
