Hi guys!

I have a device that is posting RAW data to my php site.

This is the first time I have ever worked with unknown index's.

I'm trying to see what the device is posting but all I ever get is the word "Array" or "a:0{}" or something to that matter.

Here is some of the things I have tried:

PHP Code:
if (isset($_POST))
{
$string "1 \n";
$string .= " ".$_POST." \n";
$string .= "2 \n";
$string .= " ".print_r(serialize($_POST), true)." \n";
$string .= "3 \n";
$string .= " ".var_dump($_POST)." \n";
$string .= "4 \n";
$string .= " ".var_export($_POST)." \n";
$string .= "10 \n";
foreach(
$_POST as $k => $v) {
    
$string .= "Key: {$k}<br>\r\n";
    
$string .= "Value: {$v}<br><br>\r\n";

$fp fopen('txtdump.rtf''ab');

if (
$fp)
{
fwrite($fp,$string);
fclose($fp);

echo 
'OK';

}


I can see the data in wireshark, it's a bunch of TAB delimited data but i can't for the life of me get it into a file for debugging purposes.

thanks for your input.
