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

Descrição

public static IntlChar::hasBinaryProperty ( mixed $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.

Parâmetros

codepoint: Um codepoint integer (por exemplo 0x2603 para U+2603 SNOWMAN), ou um caracter codificado como uma string UTF-8 (exemplo "\u{2603}")
property: A propriedade Unicode a inspecionar (constantes IntlChar::PROPERTY_*).

Valor Retornado

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.

var_dump(IntlChar::hasBinaryProperty("[", IntlChar::PROPERTY_CASE_SENSITIVE));
var_dump(IntlChar::hasBinaryProperty("[", IntlChar::PROPERTY_BIDI_MIRRORED));
