How can I debug php gettext?

Question

Some gettext keys aren't working for me - they show the key instead of the translation, though there is one. I'm making .mo file with PHP File_Gettext Pear library, and it seems to be working ok, so I've made the following script to try out, which keys aren't working fine:

$locale = 'en_GB';
$domain = 'messages';

setlocale(LC_ALL, $locale);
putenv("LC_ALL=".$locale);
bindtextdomain($domain, "D:/_gt");
bind_textdomain_codeset($domain, 'UTF-8');
textdomain($domain);

$mocreator = new File_Gettext_MO();
$mocreator->load('D:/_gt/en_GB/LC_MESSAGES/messages.mo');

foreach ($mocreator->strings as $key => $value) {
    if ($value == gettext($key)) {
        var_dump("ok");
    } else {
        var_dump($key, $value, gettext($key));
    }
}

From the output of the above I see that some keys work - I see a lot of oks - and some don't, yielding the following:

string 'Cancelled' (length=9)
string 'Storniert' (length=9)
string 'Cancelled' (length=9)

So there is translation in the file, but gettext fails to use them for some reason.

Answer 1

Now this is quite an old question, and I have have to point out that I'm not that well versed in gettext specific questions. But I've had some issues with array-keys as strings and encodings.

D:/_gt gives me the impression that you are using Windows of some kind, and if I'm not mistaken all Windows versions use latin-1-"with-special-locale" as default. I believe that the issue could be encoding related since you are specifying the file as utf8 but I can't help you there without the .mo file. But try switching places of the putenv and the setlocale statements.

Or spaces missing? Could the correct key be " Cancelled"?

But as someone said in the comments, this is just guesswork without the .mo file.
