Is it possible to change gettext files from PHP?

We're developing a multi-language website and in case of changes to the original text (English) they shouldn't appear on the site until all of the localized entries are changed accordingly. I don't think that's possible to do with gettext/POEdit alone (?). Another thing is concurrency of translation. If a bunch of people would edit the same gettext files on their PCs and then upload the changes to SVN, the situation when some translations were done by many people is inevitable.

T开发者_StackOverflow中文版herefore it seems to be a good idea to store changed phrases in the database and once every language has its translation, make changes to po/mo files so that there is at every moment just actual information on the site.

Is it possible to make changes to gettext translation files with PHP? If not, should we forsake gettext in lieu of storing everything in the database?

Thanks

Well, I've tried a bunch of stuff and it seems that PEAR File/Gettext is the way to go. I seems to be kind of abandoned and files, created by POEdit and File/Gettext aren't binary similar, but I've checked the differences and they are mostly in metadata (which isn't needed for the proper functioning either way), except the hashtable, which isn't handled in the PHP package, but the docs for the mo state that the hashtable isn't required either and it's questionable whether is must be contained in those files :)
