    Beschreibung

    public static Locale::canonicalize(string $locale): ?string

    Canonicalizes the passed locale string to ICU format.

    This does not necessarily indicate or return a valid locale. It is only a version of the input that has been canonicalized according to ICU rules.

    The behavior of this function depends on the version of ICU PHP is using (INTL_ICU_VERSION).

    this method performs Level 1 and Level 2 canonicalization according to ICU standards. See http://userguide.icu-project.org/locale#TOC-Canonicalization. 

echo \Locale::canonicalize ( 'en-US.utf8' ); 
// "en_U"
echo \Locale::canonicalize ( 'FR-fr@EURO' ); 
// "fr_FR@currency=EUR"
echo \Locale::canonicalize ( '' ); 
// "en_US_POSIX"
