If you want more detailed information about what's being stored in $_POST you can use

var_dump($_POST);

This will return the key, contents and type of each entry

print_r($_POST);

This will display the key and contents of each entry.

If you want to cycle through the contents of $_POST and format the output you can use.

foreach($_POST as $key => $value){
    print $key.' is '.$value.'<br />';
}

What do you mean by "the last $_POST variable"? Please provide the code snipped and the desired output format.

echo $_POST; -> "Array" print_r ($_POST); -> detailed output of the array's contents.

You mean something like this?

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