GET vs POST PHP: Key Differences

In PHP, both GET and POST are HTTP request methods used to request data from the server. The main difference between them lies in the way and purpose of passing data.

1. The GET method sends data in the URL as a query string to the server, exposing the data for users to see. This method is suitable for retrieving data, such as search queries.
2. The POST method sends data within the message body of an HTTP request to the server, so the data is not exposed in the URL, making it relatively more secure. POST method is suitable for submitting forms, uploading files, and other operations that involve sensitive information.

In general, the GET method is suitable for retrieving data, while the POST method is suitable for submitting data. In PHP, you can use the $_GET and $_POST superglobal arrays to retrieve data from GET and POST requests.
