Parsing all elements of a off-site Form?

[FoxhoundX]

Sorry if the topic title is misleading; I wasn't quite sure how to make it any more clear than that.

I want to parse all of the elements of a form and return them in a manageable form. For example, given the following form:

<form method="post" action="test.php">
<input type="text" name="sid" value="4d9f32ebc9">
<input type="text" name="name">
<input type="text" name="temp" value="1">
<input type="submit" name="test" value="test">
</form>

I would like to return something along the lines of

sid=4d9f32ebc9
name=
temp=1
test=test

I've isolated the form itself with the following code, but can't wrap my head around a good method to isolate all of the elements as long as any value associated with them:

$needle1=preg_quote("<form",'/');
$needle2=preg_quote("</form>",'/');
if(preg_match("/$needle1(.*?)$needle2/s", $return, $match))
       $form = $match[1];

The one roadblock I can think of is determining whether or not a given element has a predefined value (and if it does, parsing that value). The solution would be much more straightforward if I was not concerned with pre-existing values of the elements, but I would like to grab those as well.

Just looking for a step in the right direction. Thanks!

hope this is what you meant.

<?php


if (isset($_POST['submit'])){

foreach($_POST as $key=>$value){
	echo $key." = ".$value."<br>";
}

}

?>

<form method="post" action="">
<input type="text" name="sid" value="4d9f32ebc9">
<input type="text" name="name">
<input type="text" name="temp" value="1">
<input type="submit" name="submit" value="test">
</form>
