codepointDer Integer-Wert des Codepoints (z.B. 0x2603 für U+2603 SNOWMAN) oder das Zeichen als UTF-8 String kodiert (z.B. "\u{2603}")
Returns TRUE if
codepoint is a "graphic" character, FALSE if not.
Beispiel #1 Testen unterschiedlicher Codepoints
<?php
var_dump(IntlChar::isgraph("A"));
var_dump(IntlChar::isgraph("1"));
var_dump(IntlChar::isgraph("\u{2603}"));
var_dump(IntlChar::isgraph("\n"));
?>
