How to implement php and javascript localization?

Question

CMS

There is a self-written CMS, all Russian phrases, button names, messages, etc. now hardwired into the code, both php and javascript. At the moment, I set the task of making normal localization packs, so I want to choose some kind of universal method suitable for both php and javascript. Please tell me the implementation mechanism or specific libraries for these purposes.

Answer 1

I don't know about libraries.
I do it simply: I put all the texts in an .ini or .json file. This file is then read by the php script.
1. For the .ini file, there is a directly special function that reads the file and makes an associative array out of it. This array with texts (wrapped in a class, of course) is used both by the php script itself and in the frontend - it is inserted as json into a global variable at the very beginning of the page, before all other javascripts are loaded.
2. There should be no problems with the json file either. It's a little harder to read in php, but you don't have to worry about inserting it into the page - you can then load it with an ajax request when the frontend loads and starts working.

Answer 2

As they write above - use Gettext
There is a cross-platform program for working with Poedit localization files . Used in Django, CakePHP, WordPress
For JS, you can generate json from the information received, for example. Django, for example, provides a global function gettextand ngettext, which can be used in scripts themselves.

Answer 3

Use a templating engine like Smarty or something similar.
