What is the purpose of get and post in PHP?

In PHP, both GET and POST are the two main methods used for transferring data in the HTTP protocol.

GET: Data is passed through the URL, visible in the URL, suitable for non-sensitive data transmission such as search parameters. Data from a GET request is appended to the URL and can be accessed through the $_GET array.

Information is passed through the HTTP request body in the case of POST, making it suitable for transferring sensitive data such as form submissions. The data is not visible in the URL and can be accessed using the $_POST array.

In general, GET is used to retrieve data and POST is used to submit data. In actual development, it is necessary to choose between using GET or POST to transfer data based on specific circumstances.
