Can someone tell me the difference between $_REQUEST and the other 2 method($_GET,$_POST) for php [duplicate]

Answer 1

$_GET is for when your form uses method=get and $_POST for when it uses method=post.

Get puts the variables in the URL where they can be seen in the address bar. Post does not.

$_REQUEST is an array containing both the GET and POST parameters, and also cookies.
