CONTACT Escaping and Translating Text in WordPress WordPress core provides developers with a handful of functions to escape string content and enable translations into other languages.
Access the translated version of text used in plugins or themes with one of the following functions.
<?php echo __ ( 'Hello', 'text-domain' ); _e ( 'Hello', 'text-domain' ); echo _x ( 'Hello', 'The welcome message', 'text-domain' ); The first, __() , returns the text.
