I think this is the right list, while it isn't really active :)
ereg_replace ("[^[:alnum:]\n]", "", $t)
all japanese, russian, etc. characters remain in the string, as i'd like them to.
but when i test this same function on dragonflybsd or freebsd, all those characters get stripped out.
php.ini settings, mbstring section has the overload setting set to overload everything, so php should basically be using mb_ereg_replace. just to be sure, i tried that function specifically.
There are three possibilities: a. Function overloading doesn't work at all on those platforms for an unknown reason.
Reportedly the plain ereg_replace() malfunctions with UTF-8.
b. You are running FreeBSD on a 64 bit architecture and mb_ereg_replace() doesn't behave well with it.
Recently some 64bit related bugs were addressed in mbstring, and there are probably ones missed still.
c. BSD's libc implementation is borked and inproperly handles the argument of isalnum().
To confirm those, please try the following steps:
1. Replace every ereg_replace() by mb_ereg_replace() and then run it through.
2. Run the one-liner below on a shell prompt and include the outout in the reply
to this mail:
( echo "#include <stdio.h>"; echo "#include <ctype.h>"; echo 'main() { int i; for (i = 0; i < 256; i++) { printf("%d", isalnum(i) ? 1: 0); } printf("\n"); }' ) > /var/tmp/test.c && gcc -o /var/tmp/test /var/tmp/test.c && /var/tmp/test && rm /var/tmp/test.c /var/tmp/test
my test environments are:
win2k, sp4, apache 2.0.50, php 4.3.8 (here, it works ok)
freebsd 5.2.1, fully patched, apache-1.3.31_4, mod_php4-4.3.8_2,1 (doesn't work)
dragonflybsd, latest version, today freshly installed apache and php from ports, also doesn't work
BTW,
mbstring.language = Neutral mbstring.internal_encoding = UTF-8 mbstring.http_input = UTF-8 mbstring.http_output = UTF-8 mbstring.encoding_translation = On mbstring.substitute_character = _ mbstring.func_overload = 7
If http_input equals to internal_encoding then you don't need to turn on encoding_translation.
