determine_locale是一个WordPress的函数,它试图根据各种因素,如WPLANG常数、WP_LANG_DIR常数和网站的语言设置,来确定网站当前的地域。所得到的区域设置可以用来为网站加载适当的翻译。

确定请求所需的当前语言环境。

function determine_locale() {
	/**
	 * Filters the locale for the current request prior to the default determination process.
	 *
	 * Using this filter allows to override the default logic, effectively short-circuiting the function.
	 *
	 * @since 5.0.0
	 *
	 * @param string|null $locale The locale to return and short-circuit. Default null.
