How to save and retrieve language specific text in PHP?

Question

I am currently creating a web application that will be used by people from different countries.

Currently, all the messages that I printed (i.e. errors, etc.) are in English.

What is the best way to store language constants and get them?

It is very likely that messages may need a bit of information entered into them, as well as data entered by the user, etc.,

For example, we may have an error:

The email address '[e-mail]' was not a valid email address.

Answer 1

GNU gettext provides tools and framework for this. This is a decent article on using gettext in PHP.

Answer 2

printf(), % s:

The email address '%s' was not a valid email address.
