Question

We are in the process of making our website international, allowing multiple languages.

I’ve looked into php’s “gettext” however, if I understand it right, I see a big flaw:

If my webpage has let’s say “Hello World” as a static text. I can put the string as <?php echo gettext("Hello World"); ?>, generate the po/mo files using a tool. Then I would give the file to a translator to work on.

A few days later we want to change the text in English to say “Hello Small World”?
Do I change the value in gettext? Do I create an english PO file and change it there?
If you change the gettext it will consider it as a new string and you’ll instantly loose the current translation …

It seems to me that gradually, the content of the php file will have old text everywhere.
Or people translating might have to be told “when you see Hello World, instead, translate Hello Small World”.

I don’t know I’m getting confused.

In other programming languages, I’ve seen that they use keywords such as web.home.featured.HelloWorld.

What is the best way to handle translations in PHP?

Thanks

Answer 1

You basically asked and answered your own question, the answer might just be having a slightly better understanding of how PO files work.

Within the PO file you have a msgid and a msgstr. The msgid is the value which is replaced with the msgstr within the PHP file depending on the localization.

Now you can make those msgid’s anything you would like, you could very well make it:

<?php echo _("web.home.featured.HelloWorld"); ?>

And then you would never touch this string again within the source, you only edit the string through the PO files.

So basically the answer to your question is you make the gettext values identifiers for what the string should say, however the translators typically use the default language files text as the basis for conversion, not the identifier itself.

I hope this is clear.
