The gettext functions implement an NLS (Native Language Support) API which can be used to internationalize your PHP applications. Please see the gettext documentation for your system for a thorough explanation of these functions or view the docs at http://www.gnu.org/manual/gettext/index.html.
To use these functions you must download and install the GNU gettext package from http://www.gnu.org/software/gettext/gettext.html
To include GNU gettext support in your PHP build you must add the option --with-gettext[=DIR] where DIR is the gettext install directory, defaults to /usr/local.
