load_textdomain()

load_textdomain() — Loads a .mo file into the text domain $domain. If the text domain already exists, the translations will be merged. If both sets have the same string, the translation from the original value will be taken. On success, the .mo file will be placed in the $l10n global by $domain and will be a MO object.

Inputs: $domain (string): Text domain. Unique identifier for retrieving translated strings. $mofile (string): Path to the .mo file. $locale (string): Optional. Locale. Default is the current locale.

Returns bool: True on success, false on failure.
