(PHP 7, PHP 8)
IntlChar::hasBinaryProperty — Check a binary Unicode property for a code point
Beschreibung
$codepoint
, int $property
): ?boolChecks 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
-
Der int-Wert des Codepoints (z. B.
0x2603
für 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 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)
