get_locale() │ WP 1.5.0

Sets the global variable $locale and gets the current site locale (for example, en_US).

For the second and subsequent calls, the function will return $locale global variable passed through the locale filter.

You can get the list of locales here.

Until version 4.0, the locale was defined by WPLANG constant within the wp-config.php. Now this constant is deprecated.

Usually this function is used by one of localization functions, like load_textdomain().

Since version 5.0, it's better to use a wrapper of this function: determine_locale().

Examples

0

#1 Get the current locale 

echo get_locale();
// output is `en_US`
0

#2 Set locale on the server

This example demonstrates how to set the LC_MONETARY locale. If the base locale is not set, then specify the 'en_US' locale this way:

setlocale( LC_MONETARY, get_locale() );
$my_local_settings = localeconv();

if( ! $my_local_settings['int_curr_symbol'] ){
	  setlocale( LC_MONETARY, 'en_US' );
}
0

#3 Get the value of the current locale 

setlocale( LC_MONETARY, get_locale() );
$my_local_settings = localeconv();
print_r( $my_local_settings );

Notes

  • Global. String. $locale The current locale.
  • Global. String. $wp_local_package Locale code of the package.
