XL. funzioni iconv

Qesto moudlo contiene un'interfaccia con le funzioni della libreria iconv. Per essere abilitati ad usare queste funzioni definite in questo modulo si deve compilare l'interprete PHP usando l'opzione --with-iconv. Per fare cos�, devi avere la funzione iconv() nella libreria standard di C o libriconv installata sul tuo sistema. La libreria libiconv � reperebile presso l'indirizzo http://www.gnu.org/software/libiconv/.

La libreria iconv converte i file tra vari set di caratteri. I set di caratteri supportati dipendono dall'implementazione di iconv() sul tuo sistema. Nota che la funzione iconv() non � utilizzabile come ti aspetti su alcuni sistemi. In questo caso, dovresti installare la libreria libiconv.

Personaly I leaved all php dlls in \php\dlls\ directory, just adding this path to my system path, and iconv.dll supplied with php 4.3.2 works fine, also leaving supplied php_iconv.dll in my \php\extensions\ directory. This was working fine with Apache and Omnihttpd server I use.



As soon I installed IIS on the same server, php complained about not finding php_iconv.dll in the extensions directory. In fact PHP with IIS loads all extensions in my \php\extensions directory correctly, except php_iconv.dll. 

Although iconv.dll is in my system path, the only way to load php_iconv.dll was to copy iconv.dll file in \%winnt\system32 directory. With other servers, iconv.dll can be in anywhere in the system path.

Windows users:



If you have having troubles with this module as I did, my solution was easily found by using the packed php_iconv.dll in my extensions folder and using the downloadable version as in the post above in the %windows%\system32 folder. 



Nothing would work any other way (i.e. php_iconv.dll in my system folder or the downloaded iconv.dll in my extensions).



be safe.. downloadable goes in the system folder (as iconv.dll,  not renamed) and php_iconv.dll goes in the extensions folder (unrenamed also).



happy hunting.

If iconv reports errros like the following



iconv: illegal input sequence at position 31883



you can circumvent this problem by adding //TRANSLIT 

to your charset



print iconv( 'UTF-8', 'iso-8859-2//TRANSLIT', $inString );

I'm not sure how recent version of

glibc 2.x Slackware 7.x/8.x comes with, but

it's very likely that it comes with glibc 2.2.x.

In that case, you don't have to bother at all to

install libiconv in /usr/local. iconv(3) in glibc 2.2.x

is very good (thanks to Ulrich Drepper and

Bruno Haible. the latter is the author of libiconv).

libiconv is very handy for those outdated/non-standard-compliant Unix 

and non-Unix systems that don't have 

sufficiently good iconv(3) in their C library.

If you use the libiconv library instead of the libc's iconv support, don't forget to use libiconv() instead of iconv()

To compile libiconv under Slackware 7.0 or 8.0 without errors (either with the apache module of PHP or the CGI version), you must specify the full path of the libiconv installation.



Exemple :



       --with-iconv=/usr/local
