It works for me: echo str_replace(chr(146),"'",str_repeat("X".chr(146)."Y", 10)); X'YX'YX'YX'YX'YX'YX'YX'YX'YX'Y Also: (should be lighter and faster than str_replace, I think) echo strtr(str_repeat("X".chr(146)."Y", 10), chr(146), "'"); X'YX'YX'YX'YX'YX'YX'YX'YX'YX'Y It might be related to your input - perhaps not 8-bit clean? Perhaps preprocessed in some way through the pipe (network, linux, apache, php.ini settings, etc.) before it reached your script? Hard to guess. I would've written (in binary safe way) the input to a temp file and then inspected it via hexdump, less, hexedit etc. Kind regards, -- Abdullah Ramazanoglu aramazan ÄT myrealbox D0T cöm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
