Sorry to disturb you again, the example works fine but i want to use it inside a class and i can't get it working i tried 3 days to sort this, can you help me? I want to pay you. thanks, this is the code, i think must call inside a class? I want to retrieve some bytes (string) from a uploaded bin file and calculate the cs of it. I don't have php expenrience but with some exampe codes it will help me a lot. thanks again!

`<?php

require_once "../utils.php";
include "../crcphp/crc8.php";

class test {

public function read_only(){
return false;
}

public function accept_size($size){
	return $size == 2048;
}



public function get_data($data){

$crc8 = new Crc8();
$algoParams = $CRC_8_;
$algoName = $algoParams->Name;
echo "Name: ".$algoName."<br/>";
$check = $algoParams->Check;
print "Check:  0x".dechex($check)."<br/>";

	
		$test = ((ord($data[0x02]) & 0xFF) << 16)
			+ ((ord($data[0x01]) & 0xFF) << 8)
			+ ((ord($data[0x00]) & 0xFF) );
	$test = intval($test);


	
	$array = array();
	$array['TEST'] =round($test);
	return $array;
}

public function set_test($data, $test2){

if (isset($_POST['swap2'])) {

     $data = swap($data);

} else {

;
}
if($test2 < 0){
$test2 = 0;
} else if ($test2 > 999999){
$test2 = 999999;
}

 for($n = 0x00; $n < 0x80; $n+=16){

		$data[$n+0] = chr(($test2) & 0xFF);
		$data[$n+1] = chr(($test2 >> 8) & 0xFF);
	    $data[$n+2] = chr($test2 >>16 & 0xFF);
		

	}	

if (isset($_POST['swap2'])) {

     $data = swap($data);

} else {
;

}

	return $data;
}

}

?>

It's not good practice, but you can use it as a global variable.

$algoParams = $GLOBALS['CRC_8_'];
