PHP Gettext - No translation

问题

I am trying to use the PHP gettext extension in order to translate some strings. All functions appear to return the correct values but calling gettext()/_() returns the original string only. The PO/MO files seem correct and I believe I have set the directories up correctly. I am running WAMP Server with PHP 5.3.10 on Windows (also tried running 5.3.4 and 5.3.8 because I have the installations).

Firstly, see /new2/www/index.php:

$locale = 'esn'; # returns Spanish_Spain.1252 in var dump

putenv("LC_ALL={$locale}"); // Returns TRUE
setlocale(LC_ALL, $locale); // Returns 'Spanish_Spain.1252'

$domain = 'messages';
bindtextdomain($domain, './locale'); // Returns C:\wamp\www\new2\www\locale
bind_textdomain_codeset($domain, 'UTF-8'); // Returns UTF-8
textdomain($domain); // Returns'messages'

print gettext("In the dashboard"); // Prints the original text, not the translation.
exit;

I have created the following file structure:

www/new2/www/locale/Spanish_Spain.1252/LC_MESSAGES/messages.mo

I have also tried replacing Spanish_Spain.1252 with: es_ES, esn, esp, Spanish, and Spanish_Spain.

The PO file used to generate the MO is like so (only the relevant entry given):

#: C:\wamp\www\new2/www/index.php:76
msgid "In the dashboard"
msgstr "TRANSLATED es_ES DASHBOARD"

This was generated using PoEdit. I have restarted Apache after adding any new .MO file. Also note that I was previously using Zend_Translate with Gettext and it was translating correctly. I wish to rely on the native gettext extension, though, in part because I am attempting to create a lightweight framework of my own.

Any help would be appreciated.

Edit: Amended directory structure. Note - will be able to try recent answers within 24hrs.

I set this up on my XAMPP instance and figure it out.

Flat out setlocale does not work on Windows, so what it returns is irrelevant.
For Windows you set the locale using the standard language/country codes (in this case es_ES is Spanish as spoken in Spain)

Under your locale directory create es_ES/LC_MESSAGES/. This where your messages.mo file lives.

$locale = 'es_ES'; 

putenv("LC_ALL={$locale}"); // Returns TRUE

$domain = 'messages';
bindtextdomain($domain, './locale'); 
bind_textdomain_codeset($domain, 'UTF-8'); 
textdomain($domain); // Returns'messages'

print gettext("In the dashboard"); 
exit;

I am not sure if this made a different, but I did two things when creating the po file. In poEdit under File -> Preferences I changed the Line ending format to Windows. And after I created the initial po with poEdit I opened the file in Notepad++ and switched the encoding type to UTF-8 as poEdit did not do this.

I hope this at least points you in the right direction.

Your code mentions this as the return value from bindtextdomain:

C:\wamp\www\new2\www\locale

With the setlocale of Spanish_Spain.1252 and textdomain of messages, calls to gettext will look in this path:

C:\wamp\www\new2\www\locale\Spanish_Spain.1252\LC_MESSAGES\messages.mo

But you created the file structure of:

www/new2/locale/Spanish_Spain.1252/LC_MESSAGES/messages.mo
         ^^
         www/ missing here

Edit

Okay, so that didn't help. I've created a test script on Windows and using POEdit like you:

$locale = "Dutch_Netherlands.1252";
putenv("LC_ALL=$locale"); // 'true'
setlocale(LC_ALL, $locale); // 'Dutch_Netherlands.1252'
bindtextdomain("messages", "./locale"); // 'D:\work\so\l10n\locale'
textdomain("messages"); // 'messages'

echo _("Hello world"); // 'Hallo wereld'

My folder structure is like this:

D:\work\so\l10n\
    \locale\Dutch_Netherlands.1252\LC_MESSAGES\messages.mo
    \locale\Dutch_Netherlands.1252\LC_MESSAGES\messages.po
    \test.php

Hope it helps, although it looks almost identical to yours. A few things I found online:

It's important to set the character set in .po file
Spaces inside the localization file might have a UTF8 alternative, so be wary of key lookups failing. Probably the best thing to test first is keys without spaces at all.

回答3:

A suggestion: you may need the full locale for the .mo file. This is probably Spanish_Spain.UTF8 or esn_esn.UTF8 or esn_esp.UTF8 (not 1252, as you change the code base).

To track what directory it's looking for, you can install Process monitor (http://technet.microsoft.com/en-us/sysinternals/bb896645). It spews out bucket loads on info, but you should be able to find out which file/directory is being looked for.

(My other thought is to check file permissions - but if you already had something similar in Zend_Translate, then probably not the cause, but worth checking anyway).

Sorry if not good - but might give you a clue.

Look here. It works for me on windows and on linux also. The last values in the array works for windows. List of languages names can be found here. My catalogs are in

./locales/en/LC_MESSAGES/domain.mo
         /cs/LC_MESSAGES/domain.mo

回答5:

I have never tried using gettext on Windows, but each time I had problems with gettext on linux systems, the reason was that an appropriate language pack was not installed.

回答6:

Problem can be also that when you change your *.po and *.mo files, you have to restart the Apache Server. This can be problem, so you can use workaround - always rename these files to some new name and they will be reloaded.
