OK, UNCLE -

The Bash script is:
Code: 
#!/bin/bash

   code=171
   offset=4
   input_num=`od -j $offset -An -t u1 -v | tr "\n" " "`
   IFS=' ' read -r -a array <<< "$input_num"
   args_for_printf=""
   for element in "${array[@]}"
   do
     output=$(( $element ^ $code ))
     args_for_printf="$args_for_printf\x$(printf %x $output)"
     code=$element
   done
     printf "$args_for_printf"

I'm tired, lack of coffee, but converting it to PHP is just not working. Mainly it the "element ^ code" that's got me snowed. Can someone convert this - so I can slap my forehead - ah duh!
Output should be: {"system":{"get_sysinfo":{"sw_ver":"1.0.5 Build 2 ....

Thanks
 
Try to create a script with these steps:
1. Read the output to the array where each number is a separate element
2. Iterate array from 4th element ($offset)
3. Make a bit operation for each element to cinvert octal to decimal (octdec function) then change decimal to char (chr function)
4. Convert array to string (implode function)
5. Print output as a JSON
 
Google says that bash "^" is modulo. And for php it's "%" and my test script is giving different results. My head is hurting.
Just re-read your ans - Ta-Da! I'm pulling in an octal number and then doing module on a octal number - splat! <sigh>....
 
I was wrong. The "^" caret says XOR - as is in PHP and SOLVED.
Code: 
$in = file_get_contents ("t1");
$od = array("");
$text = "";
foreach (str_split($in, 1) as $byte) {
  $od[] = ord($byte);
}
$od = array_slice($od, 5);
$code = 171;
foreach ($od as $ele)
{
  $out = $ele ^ $code;
  $text .= sprintf ("%c", $out);
  $code = $ele;
}
echo "$text\n";
 
Because I was unable to find what I needed - here's 90% of what someone else can use
Code: 
#!/usr/bin/php

<?php

function OnOff ($ip, $oos) # OnOffStat
{
  $oosa =  base64_decode($oos);
  $stream = stream_socket_client("tcp://$ip:9999", $errno, $errstr);
  if (!$stream) {
    echo "{$errno}: {$errstr}\n";
    die();
  }
  fwrite($stream, $oosa);
  stream_socket_shutdown($stream, STREAM_SHUT_WR);
  $ret = stream_get_contents($stream);
  fclose($stream); #if close before ret= the ret=null
  return ($ret);
}

# ==== main ====
  $on = "AAAAKtDygfiL/5r31e+UtsWg1Iv5nPCR6LfEsNGlwOLYo4HyhueT9tTu36Lfog==";
  $off = "AAAAKtDygfiL/5r31e+UtsWg1Iv5nPCR6LfEsNGlwOLYo4HyhueT9tTu3qPeow==";
  $status = "AAAAI9Dw0qHYq9+61/XPtJS20bTAn+yV5o/hh+jK8J7rh+vLtpbr";

# $ARGV and a switch()
# $ret = OnOff ("sg102", "$on"); # sg102 = 192.168.0.102 address of switch
# $ret = OnOff ("sg102", "$off"); # 
# $ret = OnOff ("sg102", "$status"); # one of these of a combo

$od = array("");
foreach (str_split($ret, 1) as $byte) {
  $od[] = ord($byte);
}

$od = array_slice($od, 5); # chuck the first 4 bytes

$text = "";
$code = 171;   # the starting code - don't ask
foreach ($od as $ele)
{
  $out = $ele ^ $code; # XOR with the next byte
  $text .= sprintf ("%c", $out);
  $code = $ele;
}
echo "$text\n";
 
The above code is because I wanted "KASA" app on my Fedora laptop as kasa.php that would look and act like the Kasa app on my Android phone.
 
Hope this helps:
PHP: 
<?php

$code = 171;
$offset = 4;

// Read input from standard input
$inputNum = stream_get_contents(STDIN);
$array = array_map('intval', explode(' ', trim($inputNum)));

$argsForPrintf = '';
foreach ($array as $element) {
    $output = $element ^ $code;
    $argsForPrintf .= sprintf("\\x%02x", $output);
    $code = $element;
}

printf($argsForPrintf);
