    IntlChar::isUUppercase

    (PHP 7, PHP 8)

    IntlChar::isUUppercase — Check if code point has the Uppercase Unicode property

    Descrizione

    public static IntlChar::isUUppercase(int|string $codepoint): ?bool

    Check if a code point has the Uppercase Unicode property.

    This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_UPPERCASE)

    Nota:

    This is different than IntlChar::isupper() and will return true for more characters.

    Elenco dei parametri

    codepoint

    The int codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")

    Valori restituiti

    Returns true if codepoint has the Uppercase Unicode property, false if not. Returns null on failure.

    Esempi

    Example #1 Testing different code points

    <?php
    var_dump    (IntlChar::isUUppercase("A"));
    var_dump(IntlChar::isUUppercase("a"));
    var_dump(IntlChar::isUUppercase("Φ"));
    var_dump(IntlChar::isUUppercase("φ"));
    var_dump(IntlChar::isUUppercase("1"));
    ?>

    Il precedente esempio visualizzerà:

    bool(true)
bool(false)
bool(true)
bool(false)
bool(false)
