What is the method for retrieving form data in PHP?

In PHP, you can retrieve form data using the $_GET and $_POST arrays.

1. $_GET is used to retrieve form data submitted using the GET method. With the GET method, the form data is appended to the URL in the form of key-value pairs. Data is passed by adding key-value pairs after a question mark in the URL. For example, the URL could be: www.example.com?name=John&age=25. You can use $_GET[“name”] to retrieve the value of the name and $_GET[“age”] to retrieve the value of the age.
2. $_POST: Used to retrieve form data submitted through the POST method. With the POST method, form data is placed in the body of the HTTP request instead of appearing in the URL, making it more secure. You can use $_POST[“name”] to retrieve the value of the name and $_POST[“age”] to retrieve the value of the age.

You can retrieve form data using the $_GET and $_POST arrays and process and validate it as needed.
