IntlChar::isIDIgnorable — Check if code point is an ignorable character
Determines if the specified character should be regarded as an ignorable character in an identifier.
TRUE
for characters with general category "Cf" (format controls) as well as non-whitespace ISO controls (U+0000..U+0008, U+000E..U+001B, U+007F..U+009F).
Hinweis:
Note that Unicode just recommends to ignore Cf (format controls).
codepoint
Der 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 ignorable in identifiers, FALSE
if not.
Beispiel #1 Testen unterschiedlicher Codepoints
<?php
var_dump(IntlChar::isIDIgnorable("A"));
var_dump(IntlChar::isIDIgnorable(" "));
var_dump(IntlChar::isIDIgnorable("\u{007F}"));
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
bool(false) bool(false) bool(true)
IntlChar::PROPERTY_DEFAULT_IGNORABLE_CODE_POINT
