What is the input statement in php?

In PHP, the input statement typically refers to how data is received from users, often through forms. The most common way to capture input is by using the $_POST or $_GET superglobals, which retrieve data submitted via HTTP POST or GET methods, respectively. For example, to access a value from a form input named "username", you would use $_POST['username'] or $_GET['username']. Additionally, functions like fgets() or fscanf() can be used for reading input from the command line or files.
