Encoding issue when responding from callback script to payment gateway

[webio]

Hello,

 

I'm writing custom payment provider and I'm having difficulties with probably dbconnect.php file encoding. My payment provider company requires that when callback script will be accessed by them it must return "OK" string. Currently it returns

 

ďťżďťż

 

I've narrowed down problem to dbconnect.php file which is being included from callback script. When I comment it callback script is returning correctly OK using

 

echo("OK");

 

Any ideas?

 

Thank you

 

P.S. I've tried to change encoding of dbconnect.php file but this will not work since file is encoded by IonCube and returns error after conversion.

I've made a little crazy workaround. Instead of

 

echo("OK")

 

I'm using

 

header('Location: .....ok.php');	

 

which points to file containing only:

 

<?php
echo("OK");
?>

 

and it worked
