Beispiel #1 Testen unterschiedlicher Codepoints
<?php
var_dump(IntlChar::isJavaIDPart("A"));
var_dump(IntlChar::isJavaIDPart("$"));
var_dump(IntlChar::isJavaIDPart("\n"));
var_dump(IntlChar::isJavaIDPart("\u{2603}"));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
bool(true) bool(true) bool(false) bool(false)
