Gettext in php

Hi,

This is new and very interesting topic.
The gettext functions implement an NLS (Native Language Support) API which can be used to internationalize your PHP applications.

Hi,

If want use gettext mean you must install gettext.please read below.

To include GNU gettext support in your PHP build you must add the option --with-gettext[=DIR] where DIR is the gettext install directory, defaults to /usr/local.

Hi,

Localizing PHP web sites using gettext

Developing multi language web sites using PHP is actually very easy. A common approach is having an include file for every supported language which contains an array that maps string ids to localized text (for example "WelcomeText" => "Welcome to our homepage." would be included using something like <?= $strings["WelcomeText"] >). However there are several problems with this approach. First of all, when the application is updated and additional strings are added, there is no way to determine which new strings were added and if they are present in every language (unless you write a script for it). What happens if a newly added string is not yet translated into a specific language?

Hi,

Using gettext with PHP

A widely used framework for internationalization is gettext. It can be used with a variety of programming languages, including PHP. There are basically two ways to use gettext in your PHP applications. You can use the native gettext PHP extension or you can use a library implemented in PHP that does not need any extension, such as php-gettext.

Hi,

Using gettext in your application

Using gettext to get translated strings couldn't be easier. Just call gettext("Text to be translated") and you get a localized version of "Text to be translated" if available, or "Text to be translated" otherwise. If you're lazy, you can use _() instead of gettext().
Let's try this out. Create a new PHP file (we'll call it test.php), and insert the following code:

PHP Code:

  <?php

echo _("Hello World!");

?>

When you open that page in your browser, you will see "Hello World!".

Hi,

I think this extension has no configuration directives defined in php.ini and this extension has no resource types defined and this extension has no constants defined.

Hi,

bind_textdomain_codeset

Specify the character encoding in which the messages from the DOMAIN

message catalog will be returned. This bind_textdomain_codeset used to

PHP 4 >= 4.2.0, PHP 5

Hi,

The bindtextdomain() function sets the path for a domain. It returns the full pathname for the domain currently being set.

bindtextdomain() example

PHP Code:

  <?php

 
$domain = 'myapp';

echo bindtextdomain($domain, '/usr/share/myapp/locale'); 

 
?>

This will output:

/usr/share/myapp/locale

Hi,

ngettext() returns correct plural form of message identified by msgid1 and msgid2 for count n. Some languages have more than one form for plural messages dependent on the count.

ngettext() example

PHP Code:

  <?php

 
setlocale(LC_ALL, 'cs_CZ');

printf(ngettext("%d window", "%d windows", 1), 1); 

printf(ngettext("%d window", "%d windows", 2), 2); 

printf(ngettext("%d window", "%d windows", 5), 5); 

 
?>

This will output
1
2
5
