Difference between GET and POST methods?

I am new to this forum and I have been learning PHP from this night.

I want to submit a form, but I do not know the difference between:

<form action="page2.php" method="GET">

and

<form action="page2.php" method="POST">

Can anybody help me?

Thank.

HTTP-, PHP.

$ _ GET is appended to the end or URL. i.e. http://example.org/?foo=bar Get access to it in PHP with:

$foo = $_GET['foo'];

or $ foo = $ _REQUEST ['foo'];

GET is used for information that you do not mind to see people, and can be manually entered in links and URLs to get results.

$ _ POST is not displayed in your URL and is usually used after submitting the form. Access it in PHP with:

$foo = $_POST['foo'];

or $ foo = $ _REQUEST ['foo'];
