form variables

[thomasanup]

any body know how to extract form variables from an html page

for example if a code is like
<form action="test.php" method="post">
<input type="text" name="username">
<input type="text" name="passwd">
</form>

the script should output the names of variables

output:
username
passwd

this is what you should write on test.php
<?
$user=$HTTP_POST_VARS["username"];
$pass=$HTTP_POST_VARS["passwd"];

echo "username: ". $user."<br>;
echo "password: ". $pass."<br>;
?>

it must be work!

dear

this is not i want . I want the form variables from an already hosted site's html form variables. For example if i give the url of the yahoo registration page the script should output the form variables.

to interact such as posting variable to another server from your server, grabing data etc, you can try FSOCKOPEN function, you can see it at www.php.net

I tried this (FSOCKOPEN) and getting the html page
as a string.My requirement is to get the form variables from this string.The difficulty is the non uniformity in variable names. for example
<input type="text" name="test">
and
<input type=text name=test>
both are valid.So it is very difficult to develop a parser for this .Anybody having an idea please inform
