"<br><br>"; // I get variable results, between 8077 and 8083 echo "ris=$ris<br><br>"; /* I get again not writeble or "invisible" characters in IE5; on Netscape I get (eg) "04ffd9R" at the end of the

some ways to work around the problem are: rewriting and re-reading the output of bin2hex; or reconstructing the string piece by piece, with something like [$s2 is bin2hex' output] : for ($i=0; $i < strlen($s2); $i=$i+100 ) { $ricostr = $ricostr.substr($s2,$i, 100); } in both cases, the next step of the script (that looks for "0d0a0d0a") works right; I've looked into the string.c but it seems fine, I don't know what to think; thank you for any help, contact me if you need more infos, bye, Giuse --------------------------------------------------------------------------- The remainder of the
