    版本:php7

    (PHP 7)

    Check if code point has the Lowercase Unicode property

    说明

    publicstaticIntlChar::isULowercase(mixed $codepoint): bool

    Check if a code point has the Lowercase Unicode property.

    This is the same asIntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_LOWERCASE)

    Note:

    This is different than IntlChar::islower() and will return TRUE for more characters.

    参数

    $codepoint

    The integer codepoint value(e.g.0x2603forU+2603 SNOWMAN), or the character encoded as a UTF-8 string(e.g."u{2603}")

    返回值

    Returns TRUE if$codepointhas the Lowercase Unicode property,FALSE if not.

    范例

    Testing different code points

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

    以上例程会输出:

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