WordPress中__()、_e、_ex()等函数的正式名称是什么？

Hey there! Let's break down the official names and core roles of these WordPress functions, which are all part of the platform's internationalization (i18n) and localization (l10n) toolkit:

• __(): Its official name is "Retrieve Translated String". This function fetches the translated version of a string but doesn't output it directly—you'll need to use something like echo to display it. For example: echo __('Welcome to our site', 'my-theme-domain');
• _e(): Goes by the official name "Display Translated String". Unlike __(), this one outputs the translated string immediately, so you don't need an extra echo. Usage example: _e('Welcome to our site', 'my-theme-domain');
• _ex(): Officially called "Retrieve Translated String with Context". This is super useful when a single word has different meanings depending on context. You pass an extra context parameter to clarify, like: _ex('Post', 'as a verb (e.g., post a comment)', 'my-plugin-domain'); vs _ex('Post', 'as a noun (e.g., a blog post)', 'my-plugin-domain');—this helps translators pick the right translation for each scenario.

All these functions exist to make WordPress themes and plugins easy to localize for different languages and regions.
