What's the difference between POST and raw POST in PHP at all?

Question

I have this question after reading the answer here, what\'s the difference at all?

Is it possible to submit raw POST with html ?

Answer 1

$HTTP_RAW_POST_DATA will contain something like:

beans=cheese&spam=eggs&one=two

PHP splits this up for you, and shoves it in the $_POST array. Naively, it does something like this:

$parts = explode('&', $HTTP_RAW_POST_DATA);
foreach ( $parts as $part ) {
    list($key, $value) = explode('=', $part, 2);
    $_POST[$key] = $value;
}

Using JavaScript, which can be embedded into HTML, you can POST anything you like with AJAX. Something like this:

var req = new XMLHttpRequest();
req.open('POST', 'http://www.example.com/my_url' true);
req.send('any data you want');

will allow you to POST arbitrary things to the web server.
