I'm using the PEAR Crypt_Blowfish module. When I decrypt the encrypted

get rid of those extra bytes? I've tried both trim($x,'\ufffd') and
trim($x,utf8_decode('\ufffd')).
trim() is meant to remove chars from the beginning and ending of a string.
http://us2.php.net/str_replace is meant to remove a set of chars from a
string. Anywhere within the string.
But it *is* a single char that I'm wanting to remove (multiple times).
Perhaps you are confusing a char with a byte?
Nope, not confused, but I ASSUMED that maybe the chars were not at the beginning or ending of the
string, but somewhere in the middle. ( you didn't say where the chars were )
And since you were using trim(), that you were using the wrong function. Which only works on the
beginning and ending of a string.
Anyway, the problem is solved from the other end. So long as the
original string has a length that is a multiple of 8 the encoded/decoded
result has no extra chars. Padding the initial string with spaces makes
it easy to then trim() the output.
