6 [1] PHP is actually cyrillic, and translates roughly to
7 "works-doesn't-work" (UTF-8: Ради-Не-Ради)
12 How many times did you look for a good translation tool, and
13 found out that gettext is best for the job? Many times.
15 How many times did you try to use gettext in PHP, but failed
16 miserably, because either your hosting provider didn't support
17 it, or the server didn't have adequate locale? Many times.
19 Well, this is a solution to your needs. It allows using gettext
20 tools for managing translations, yet it doesn't require gettext
21 library at all. It parses generated MO files directly, and thus
22 might be a bit slower than the (maybe provided) gettext library.
24 PHP-gettext is a simple reader for GNU gettext MO files. Those
25 are binary containers for translations, produced by GNU msgfmt.
29 I got used to having gettext work even without gettext
30 library. It's there in my favourite language Python, so I was
31 surprised that I couldn't find it in PHP. I even Googled for it,
34 So, I said, what the heck, I'm going to write it for this
35 disguisting language of PHP, because I'm often constrained to it.
39 o Support for simple translations
40 Just define a simple alias for translate() function (suggested
41 use of _() or gettext(); see provided example).
43 o Support for ngettext calls (plural forms, see a note under bugs)
44 You may also use plural forms. Translations in MO files need to
45 provide this, and they must also provide "plural-forms" header.
46 Please see 'info gettext' for more details.
48 o Support for reading straight files, or strings (!!!)
49 Since I can imagine many different backends for reading in the MO
50 file data, I used imaginary abstract class StreamReader to do all
51 the input (check streams.php). For your convenience, I've already
52 provided two classes for reading files: FileReader and
53 StringReader (CachedFileReader is a combination of the two: it
54 loads entire file contents into a string, and then works on that).
55 See example below for usage. You can for instance use StringReader
56 when you read in data from a database, or you can create your own
57 derivative of StreamReader for anything you like.
62 Report them on https://bugs.launchpad.net/php-gettext
66 Put files streams.php and gettext.php somewhere you can load them
67 from, and require 'em in where you want to use them.
69 Then, create one 'stream reader' (a class that provides functions
70 like read(), seekto(), currentpos() and length()) which will
71 provide data for the 'gettext_reader', with eg.
72 $streamer = new FileStream('data.mo');
74 Then, use that as a parameter to gettext_reader constructor:
75 $wohoo = new gettext_reader($streamer);
77 If you want to disable pre-loading of entire message catalog in
78 memory (if, for example, you have a multi-thousand message catalog
79 which you'll use only occasionally), use "false" for second
80 parameter to gettext_reader constructor:
81 $wohoo = new gettext_reader($streamer, false);
83 From now on, you have all the benefits of gettext data at your
85 print $wohoo->translate("This is a test");
86 print $wohoo->ngettext("%d bird", "%d birds", $birds);
88 You might need to pass parameter "-k" to xgettext to make it
89 extract all the strings. In above example, try with
90 xgettext -ktranslate -kngettext:1,2 file.php
91 what should create messages.po which contains two messages for
94 I suggest creating simple aliases for these functions (see
95 example/pigs.php for how do I do it, which means it's probably a
99 Usage with gettext.inc (standard gettext interfaces emulation)
101 Check example in examples/pig_dropin.php, basically you include
102 gettext.inc and use all the standard gettext interfaces as
105 http://www.php.net/gettext
107 The only catch is that you can check return value of setlocale()
108 to see if your locale is system supported or not.
113 See in examples/ subdirectory. There are a couple of files.
114 pigs.php is an example, serbian.po is a translation to Serbian
115 language, and serbian.mo is generated with
116 msgfmt -o serbian.mo serbian.po
117 There is also simple "update" script that can be used to generate
118 POT file and to update the translation using msgmerge.
122 o Improve speed to be even more comparable to the native gettext
125 o Try to use hash tables in MO files: with pre-loading, would it
128 Never-asked-questions:
130 o Why did you mark this as version 1.0 when this is the first code
133 Well, it's quite simple. I consider that the first released thing
134 should be labeled "version 1" (first, right?). Zero is there to
135 indicate that there's zero improvement and/or change compared to
138 I plan to use version numbers 1.0.* for small bugfixes, and to
139 release 1.1 as "first stable release of version 1".
141 This may trick someone that this is actually useful software, but
142 as with any other free software, I take NO RESPONSIBILITY for
143 creating such a masterpiece that will smoke crack, trash your
144 hard disk, and make lasers in your CD device dance to the tune of
145 Mozart's 40th Symphony (there is one like that, right?).
149 Yes, you can. This is free software (as in freedom, free speech),
150 and you might do whatever you wish with it, provided you do not
151 limit freedom of others (GPL).
153 I'm considering licensing this under LGPL, but I *do* want
154 *every* PHP-gettext user to contribute and respect ideas of free
155 software, so don't count on it happening anytime soon.
157 I'm sorry that I'm taking away your freedom of taking others'
158 freedom away, but I believe that's neglible as compared to what
159 freedoms you could take away. ;-)
