IntlChar::getIntPropertyValue — Get the value for a Unicode property for a code point

Beschreibung

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

Gets the property value for an enumerated or integer Unicode property for a code point. Also returns binary and mask property values.

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 the numeric value that is directly the property value or, for enumerated properties, corresponds to the numeric value of the enumerated constant of the respective property value enumeration type. Returns null on failure.

Returns 0 or 1 (for false/true) for binary Unicode properties.

Returns a bit-mask for mask properties.

Returns 0 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.

Beispiele

Beispiel #1 Testen unterschiedlicher Eigenschaften

<?php
var_dump(IntlChar::getIntPropertyValue("A", IntlChar::PROPERTY_ALPHABETIC) === 1);
var_dump(IntlChar::getIntPropertyValue("[", IntlChar::PROPERTY_BIDI_MIRRORED) === 1);
var_dump(IntlChar::getIntPropertyValue("Φ", IntlChar::PROPERTY_BLOCK) === IntlChar::BLOCK_CODE_GREEK);
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

bool(true)
bool(true)
