IntlChar::isUWhiteSpace

(PHP 7, PHP 8)

IntlChar::isUWhiteSpace — Check if code point has the White_Space Unicode property

Beschreibung

public static IntlChar::isUWhiteSpace(int|string $codepoint): ?bool

Check if a code point has the White_Space Unicode property.

This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_WHITE_SPACE)

Hinweis:
This is different from both IntlChar::isspace() and IntlChar::isWhitespace().

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}")

Rückgabewerte

Returns true if codepoint has the White_Space Unicode property, false if not. Returns null on failure.

Beispiele

Beispiel #1 Testen unterschiedlicher Codepoints

<?php
var_dump(IntlChar::isUWhiteSpace("A"));
var_dump(IntlChar::isUWhiteSpace(" "));
var_dump(IntlChar::isUWhiteSpace("\n"));
var_dump(IntlChar::isUWhiteSpace("\t"));
var_dump(IntlChar::isUWhiteSpace("\u{00A0}"));
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

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