Raw data usually means it has not been processed in any way. For example. all the user data that comes in the $_POST array is in string format. It needs to be converted if you want to work with it as a float or something else, or you might need to filter it, sort it, combine it, etc.

Oh.. I found that (int) $var; can convert that.... But, when i type a string "aaa" in the input, the result's always be 0... How to make the result become a string "aaa" too ? And, When i type a float number, how to make the result become a float too ? Can you tell me how to do that ?

SOLVED!!! I found this myself

<?php// Functions function raw(){if (preg_match('/^[0-9]+$/', $_POST['post'])) {$a = (int) $_POST['post'];var_dump($a);} else if (preg_match('/^[0-9]+\.[0-9]+$/', $_POST['post'])) {$a = (float) $_POST['post'];var_dump($a);} else {$a = (string) $_POST['post'];var_dump($a);}} ?><!DOCTYPE html><html><head><meta charset="utf-8"><title>$_POST check type</title></head><body><form action="" method="post"><label for="post">Check the type</label><input type="text" id="post" name="post"></form><?php if (isset($_POST['post'])): ?><p>The type is <?php raw(); ?></p><?php endif; ?></body></html>
