W takich dniach, jak ten, nie żałuję, że wykupiłem abonament. Korzystam z porad na tych stronach nawet kilkanaście razy w tygodniu i dzięki nim prace nad stronami dla klientów idą mi o wiele szybciej, a strony wyglądają bardziej profesjonalnie. Nie wiem, jak mogłem wcześniej pracować bez dostępu do porad w tym serwisie!

CVII. GNU Recode Functions
This module contains an interface to the GNU Recode library. The GNU
Recode library converts files between various coded character sets and
surface encodings. When this cannot be achieved exactly, it may get rid
of the offending characters or fall back on approximations. The library
recognises or produces nearly 150 different character sets and is able to
convert files between almost any pair. Most
RFC 1345 character sets are
supported.
Notatka: To rozszerzenie nie jest
dostępne na platformie Windows.
You must have GNU Recode 3.5 or higher installed on your system.
You can download the package from http://www.gnu.org/directory/All_GNU_Packages/recode.html.
| Ostrzeżenie |
The Recode library version 3.6 adds weird characters behind converted
strings under certain circumstances. Thus it's safer to use Recode v3.5
or one of the available alternatives like the
iconv or
mbstring extension.
|
To be able to use the functions defined in this
module you must compile your PHP interpreter using the
--with-recode[=DIR]
option.
| Ostrzeżenie |
Crashes and startup problems of PHP may be encountered
when loading the recode as extension after loading any extension of mysql or imap. Loading the recode before those
extension has proved to fix the problem. This is due a technical problem
that both the c-client library used by imap and recode have their own
hash_lookup() function and both mysql and recode have
their own hash_insert function.

| Ostrzeżenie | Rozszerzenie IMAP nie może być używane w połączeniu z
rozszerzeniami recode i YAZ. Dzieje się tak z powodu dzielenia tego samego
symbolu wewnętrznego. |
To rozszerzenie nie definiuje posiada żadnych
dyrektyw konfiguracyjnych w pliku php.ini. To rozszerzenie nie posiada żadnych rodzajów zasobów. To rozszerzenie nie posiada żadnych stałych.

I see that the Recode (3.6) module is also incompatible with the MySQL module as well as the others noted in the "warning" note above.

Hope this might help someone:
I tried to compile php 4.3.2-RC2 (+some older versions) with recode AND imap (and gd+png+jpeg support, ldap, gettext, zlib .. but these are not interesting right now).
Why? I needed to run Imp + Horde + Turba. Turba talks to LDAP directory (and LDAP uses utf-8 encoding which I need to convert to iso-8859-2), so I modified Turba to use 'recode' for charset conversions utf8<->iso8859-2.
System: FreeBSD4.7+Apache 1.3.27+Ben SSL
I either could not properly compile OR after compiling apache coredumped.
Problem was: imap (libc-client) and recode (librecode) use the same function hash_lookup(). Therefore during loading libphp.so (and libraries it depended on) whole apache crashed. Without a word of what's going on.
The problem is detectable by forcing static linking (in FreeBSD modify librecode.la and change
library_names='librecode.so.0 librecode.so librecode.so'
to
library_names='librecode.a'
Now during linking of php the linker complains of double definition of hash_lookup.
Solution:
-grab recode3.6 from ftp://ftp.gnu.org/pub/gnu/recode/
-unpack, go to src, in files combine.c, hash.c, names.c, recode.c, testdump.c, html.c, hash.h replace hash_lookup() by hash_lookupX() [or invent some better name],
compile recode (i had to do:
setenv CFLAGS "-I/usr/local/include"
setenv LDFLAGS "-L/usr/local/lib -lintl"
./configure --prefix=/usr/local/recode --exec-prefix=/usr/local/recode --without-included-gettext
make
make check
make install
(recode is installed to /usr/local/recode.You can change this and you can force static linking of recode, so that after building libphp.so this modified recode is no longer needed and can be deleted! )
For some reason this recode needs to have externally defined
int error;
therefore we have to modify configure script +one .c php source file:
1. modify configure script of php: find
recode_format_table();
and somewhere before start of main() add
int error;
so the result is:
char *program_name;
int error;
int main() {
recode_format_table();
; return 0; }
(I modified both occurences of recode_format_table() in configure of php4.3.2rc2)
2. run configure, should work ok (my another problem was with imap: though my c-client was compiled WITHOUT ssl, configure complained that it IS using ssl, so i had to edit configure once again and comment following lines:
void mm_searched(void){}
void mm_expunged(void){}
// char ssl_onceonlyinit(); --- commented
int main() {
// ssl_onceonlyinit(); --- commented
return 0;
}
Now configure was rather happy :-)
for the record: I did
./configure --with-apxs=/usr/local/apache/bin/apxs --with-imap --enable-sysvsem --enable-sysvshm --with-sybase=/usr/local/freetds --with-gettext --with-ldap --with-zlib --with-recode=/usr/local/recode -with-gd=/usr/local --with-jpeg-dir=/usr/local --with-png-dir=/usr/local
3. edit ext/recode/recode.c (or any other .c source file, add somewhere (e.g. at the end)
int error;
without it during linking 'error not defined' will be complained.
4. do 'make' and php is yours :-)
It took me 2 days.. so do not delete this note, someone might even find it useful and mail me his thanks :-]

When compiling PHP into Apache as static module Apache configure will complain about an undefined symbol in librecode. You need recode-3.6 (e.g. on ftp://ftp.gnu.org/pub/gnu/recode/) to get rid of this error. It doesn't matter if you're compiling PHP as DSO.
