Description:
------------
In Using The following code the datatype does not returns correctly in output.
i sent name value in '123' in html page but here i will only get string value,
in similar results in if i set name = 12.32 , null.

<html>
<form name = "post" >
<input type = "text" name = "name" />
<input type = "submit" name = "submit" />

<?php
echo gettype($_POST['name']);
?>

Expected result:
----------------
1) if i set the html text box value as number it returns integer
2) if i set the html text box value as text it returns string
3) if i set the html text box value as null it returns NULL

As the new summary says, values in $_GET and $_POST are strings. Well, strings or arrays. Naturally that is the same for $_REQUEST. And it's the case for $_COOKIE too. And even $_SERVER and $_ENV.

Anyways, PHP will not try to determine integers or floats, and definitely will not interpret the string "null" to be literally NULL.

I don't actually see this documented, though I do think it has been somewhere...

May be some Error in your form?

Your will edit the form like as
`<form action="?" method="post">`
or 
`<form action="?" method="get">`
test it again.

Actually, the section "Determining variable types"[1] is even rather
misleading.

Thank you for the report, and for helping us make PHP better.

Documentation was indeed a bit misleading, added a comment on the fact that everything coming as strings per the HTTP protocol, PHP doesn't apply any kind of conversion on those input.

Fixed in the documentation as per SVN revision r342844.
