form fields count and names to PHP

I have form with changable content of textareas, from 1 to 5, each time with different names. I cannot modify the form itself.

how can i get number of textareas in form and names of them (it would be the best if i could do it clean in php without javascript).

the form is using method="POST" and PHP version is 5.2+

EDIT: i forgot to tell you that i have only textareas in form.

if you post form to php script, $_POST variable is array. then you can use something like this:

foreach($_POST as $v){} to get every field.

You could do something along the lines of :

$count=0;
$formElements=array();
foreach ($_POST as $key => $val)
{
    $count++;
    $formElements[]=$key;
}

echo "The form as $count elements.";
var_dump($formElements);

If you want the values of the post you could make a two dimensional array like this:

foreach ($_POST as $key => $val)
{
    $count++;
    $formElements[]=array($key => $val);
}
