Just been doing some heavy translation from German to English. Which lead to writing a simple command line tool for translating via Google - waste time to save time in other words. Getting a prototype up from scratch took about 15 minutes (which sheds a light on blog spam I guess). Have cleaned it up a bit and dropping it here in case anyone can use it.
Two major things that still need doing;
- validation of the language pair CLI option, to keep users sane
- character set conversion - right now getting UFT8 from Google so XML_HTMLSax can parse correctly (it relies on the str_ functions) but not doing anything clever after that.
…and there’s probably a bug or three.

Nice work.
Not to sound picky or anything, your link is ww.php.net, just missing a double you.
But yes nice work. Could come in handy.

Nice work. I had to do something similar a few years ago. I had all my language stuff in define()’s in a set PHP file so I found the easiest way was to just read all the constants from that file and echo them in a
define(LANG_HELLO, ‘Hello there’);
became …
I could then use CURL to send the stuff to google and read it back. Because of the very simple HTML format I could get away hacking some Regular expressions to put the PHP file back :-)
Those where the days when my programming knowledge was a bit naff.

I did a similar thing with Java.. it is embeddable in applications (ie. jEdit via macros). It works with all of the Google translations as we as excite.

There are a number of important considerations when developing a shrink-wrapped software package. Perhaps you are planning to deliver your application on installation media (CD/DVD) or via your website as a download. If so, you need to consider:

Nice work.
