Gettext Installation You might need to install Gettext and the related PHP library by using your package manager, like apt-get or yum.

Here we will also be using Poedit to create translation files. Structure Types of files There are three files you usually deal with while working with gettext. Domains There are some cases, in big projects, where you might need to separate translations when the same words convey different meaning given a context. In those cases, you split them into different domains. In Symfony projects, for example, domains are used to separate the translation for validation messages.

Locale code A locale is simply a code that identifies one version of a language. It is defined following the ISO and ISO alpha-2 specs: two lower-case letters for the language, optionally followed by an underline and two upper-case letters identifying the country or regional code.

For rare languages , three letters are used. For some speakers, the country part may seem redundant. Directory structure To use Gettext, we will need to adhere to a specific structure of folders. First, you will need to select an arbitrary root for your l10n files in your source repository.

Plural forms As we said in the introduction, different languages might sport different plural rules. However, gettext saves us from this trouble once again. When creating a new. When calling Gettext in code, you will have to specify the number related to the sentence, and it will work out the correct form to use - even using string substitution if needed.

Plural rules include the number of plurals available and a boolean test with n that would define in which rule the given number falls starting the count with 0. It also includes view helpers, and locale-aware input filters and validators. However, it has no message extractor.

Other frameworks also include i18n modules, but those are not available outside of their codebases: Laravel supports basic array files, has no automatic extractor but includes a lang helper for template files.

Yii supports array, Gettext, and database-based translation, and includes a messages extractor. It is backed by the Intl extension, available since PHP 5.

If you decide to go for one of the libraries that provide no extractors, you may want to use the gettext formats, so you can use the original gettext toolchain including Poedit as described in the rest of the chapter.

Directory structure To use Gettext, we will need to adhere to a specific structure of folders. Catch an exception only if you have a handling scenario other than just reporting it. Otherwise just let it bubble up to a site-wide handler note that you don't have to write one, there is a basic built-in handler in PHP, which is quite good. The only exception pun not intended is the creation of the PDO instance, which in case of error might reveal the connection credentials that would be the part of the stack trace.

In order to hide them, we can wrap the connection code into a try.. A long rant on the matter: Despite a widespread delusion, you should never catch errors to report them.

A module like a database layer should not report its errors. This function has to be delegated to an application-wide handler. All we need is to raise an error in the form of exception - which we already did.

That's all. Quite contrary, catching an exception should be rather an exceptional case pun intended.

In fact, there is nothing special in PDO exceptions - they are errors all the same. Thus, you have to treat them exactly the same way as other errors.You can view the progress of statements executing in the background in a progress bar located on the lower right side of the status bar. Create the Microsoft Transform file, using any appropriate tool.

The most classic way and often taken as reference for i18n and l10n is a Unix tool called gettext. If you go through the entire tutorials, you will know how to manage MySQL databases and manipulate data using various techniques such as SQL queries, MySQL stored procedures , database views , triggers.
