    IntlChar::hasBinaryProperty — Check a binary Unicode property for a code point

    Опис

    public static IntlChar::hasBinaryProperty(int|string $codepoint, int $property): ?bool

    Checks a binary Unicode property for a code point.

    Unicode, especially in version 3.2, defines many more properties than the original set in UnicodeData.txt.

    The properties APIs are intended to reflect Unicode properties as defined in the Unicode Character Database (UCD) and Unicode Technical Reports (UTR). For details about the properties see » http://www.unicode.org/ucd/. For names of Unicode properties see the UCD file PropertyAliases.txt.

    Параметри

    codepoint

    Значення кодової точки типу int (наприклад 0x2603 для U+2603 SNOWMAN) або символ UTF-8 типу string (напр. "\u{2603}")

    property

    Властивість Unicode, яка шукається (див. конастанти IntlChar::PROPERTY_*).

    Значення, що повертаються

    Returns true or false according to the binary Unicode property value for codepoint. Also false if property is out of bounds or if the Unicode version does not have data for the property at all, or not for this code point. Returns null on failure.
