I've rescued an old project that was originally writted only for spanish audience and now I have to internationalize it.
This project has 3 kinds of text strings:
<html>...<body>...<p>Hello world</p>...First is not a problem, because there are really few strings and very localized. The second case is also very localized so it's not really a big problem. But last 2 cases are unmanegeable: hundreds of HTML files (static + database) with hundreds of strings inside.
So, I'm looking for an automatized method to extract all strings into a recognizable format, give it to translators and then have my pages in other languages.
Does exist something similar or should I create a custom solution? In this case, any idea?

Machine translation uses software like Google Translate to automatically translate content from the source language to the target language. Professional translators study for years to perfect fluency in multiple languages and manually translate one language to another.
When you come across a page written in a language that you don't understand, you can use Chrome to translate the page. On your computer, open Chrome. Go to a web page written in another language. On the right of the address bar, click Translate .
Ok. The I18n (Internationalization) is a quite strange thing. You have to make many many changes to your code in order to make it multilingual.
For me, the best solution is to move it on CakePHP that already support the I18n in many layers. But this solution will make you spend a lot of time. So ....
A fast method for translating internal texts like
echo "Hello World"
or
<p>Hello World</p>
Is to create an appropriate language file with php extension for each language (ie: es.php, el.php, en.php, an so on) that will contain an array with keys and values that will looks like that :
$l = array(
'WEB_TITLE' => 'My web site title',
'GEN_HELLO' => 'Hello World',
'MENU_HOME' => 'Home',
'MENU_PRODUCTS' => 'Products',
...
);
Then into your web site you have to load the appropriate language file at the very beginning of each page and into your page you have to do something like that:
echo $l['GEN_HELLO'];
and
<p><?php echo $l['GEN_HELLO']; ?></p>
That is the front end side of your application. Now to make your data multilingual you have to change the database structure in some how.
Lets say you have that table
ARTICLES
id Title Content Date Active
In the above structure you have to make Title and Content I18n compatible. In order to translate that columns you have to create another table called in example ARTICLES_L that will looks like that
ARTICLES_L
ID POST_ID COLUMN LANGUAGE CONTENT
In the above table you have to store the article id, the column that the translation belongs (ie: title) the language, and the translated content.
So if you have that records in ARTICLES
ARTICLES
id Title Content Date Active
1 Title 1 This is content 1 2011-10-01 13:28:45 1
2 Title 2 This is content 2 2011-10-01 13:28:45 1
3 Title 3 This is content 3 2011-10-01 13:28:45 1
The table ARTICLES_L will contain that records
ARTICLES_L
ID POST_ID COLUMN LANGUAGE CONTENT
1 1 title es_ES Título 1
2 1 content es_ES Este es el contenido 1
3 1 title el_GR Τίτλος 1
4 1 content el_GR Αυτό είναι το περιεχόμενο 1
5 2 title es_ES Título 2
6 2 content es_ES Este es el contenido 1
....
In reality there are many many other tasks you have to do, but this is the idea behind the solution I am giving to you :)
Good Luck
PN : Even better for the front end of your application is to use that http://php.net/manual/en/book.gettext.php This way is the way that used from WordPress and CakePHP, but in very low level :? Just take a look. This will be better than creating files for each language.
