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

Açıklama

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.

Bağımsız Değişkenler

codepoint: int türünde Unicode karakter kodu (örn. U+2603 SNOWMAN için 0x2603) veya string türünde Unicode karakter kodu (örn. "\u{2603}")
property: Aranacak Unicode özelliği (bkz. IntlChar::PROPERTY_* sabitleri).

Dönen Değerler

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.
