Beispiele
Beispiel #1 Testen unterschiedlicher Codepoints
<?php
var_dump(IntlChar::iswhitespace("A"));
var_dump(IntlChar::iswhitespace(" "));
var_dump(IntlChar::iswhitespace("\n"));
var_dump(IntlChar::iswhitespace("\t"));
var_dump(IntlChar::iswhitespace("\u{00A0}"));
?>
Das oben gezeigte Beispiel erzeugt folgende
Ausgabe:
bool(false)
bool(true)
bool(true)
