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

    Beschreibung

    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.

    Parameter-Liste

    codepoint

    Ein Wert vom Typ int, der einen Codepoint darstellt (z. B. 0x2603 für U+2603 SNOWMAN) oder ein als UTF-8-String kodiertes Zeichen (z. B. "\u{2603}")

    property

    Die Unicode-Eigenschaft, die gesucht werden soll (siehe die IntlChar::PROPERTY_*-Konstanten).

    Rückgabewerte

    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.

    Beispiele

    Beispiel #1 Testen unterschiedlicher Eigenschaften

    <?php
    var_dump    (IntlChar::hasBinaryProperty("A", IntlChar::PROPERTY_ALPHABETIC));
    var_dump(IntlChar::hasBinaryProperty("A", IntlChar::PROPERTY_CASE_SENSITIVE));
    var_dump(IntlChar::hasBinaryProperty("A", IntlChar::PROPERTY_BIDI_MIRRORED));
    var_dump(IntlChar::hasBinaryProperty("[", IntlChar::PROPERTY_ALPHABETIC));
    var_dump(IntlChar::hasBinaryProperty("[", IntlChar::PROPERTY_CASE_SENSITIVE));
    var_dump(IntlChar::hasBinaryProperty("[", IntlChar::PROPERTY_BIDI_MIRRORED));
    ?>

    Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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