    IntlChar::isULowercase

    (PHP 7, PHP 8)

    IntlChar::isULowercase — Check if code point has the Lowercase Unicode property

    Description

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

    Check if a code point has the Lowercase Unicode property.

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

    Note:

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

    Parameters

    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}")

    Return Values

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

    Examples

    Example #1 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"));
    ?>

    The above example will output:

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