(PHP 7, PHP 8)
IntlChar::getIntPropertyValue — Get the value for a Unicode property for a code point
Beschreibung
$codepoint, int $property): ?intGets the property value for an enumerated or integer Unicode property for a code point. Also returns binary and mask property values.
Parameter-Liste
-
codepoint -
Der int-Wert des Codepoints (z. B.
0x2603für U+2603 SNOWMAN) oder das Zeichen als UTF-8-String kodiert (z.B."\u"). -
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

var_dump(IntlChar::getIntPropertyValue("Φ", IntlChar::PROPERTY_BLOCK) === IntlChar::BLOCK_CODE_GREEK);
