(PHP 7, PHP 8)
IntlChar::isIDPart — Check if code point is permissible in an identifier
$codepoint): ?boolDetermines if the specified character is permissible in an identifier.
true for characters with general categories "L" (letters), "Nl" (letter numbers), "Nd" (decimal digits),
"Mc" and "Mn" (combining marks), "Pc" (connecting punctuation), and u_isIDIgnorable(c).
Bilginize:
This is almost the same as Unicode's ID_Continue (
IntlChar::PROPERTY_ID_CONTINUE) except that Unicode recommends to ignore Cf which is less than IntlChar::isIDIgnorable().
codepoint
int türünde Unicode karakter kodu (örn. U+2603
SNOWMAN için 0x2603) veya string
türünde Unicode karakter kodu (örn. "\u{2603}")
Returns true if
codepoint is the code point may occur in an identifier, false if not. Returns null on failure.
