(PHP 7, PHP 8)
IntlChar::isIDPart — Check if code point is permissible in an identifier
Determines 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).
Nota:
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
Um codepoint integer (por exemplo 0x2603
para U+2603 SNOWMAN), ou um caracter codificado como uma string UTF-8 (exemplo "\u{2603}"
)
Returns true
if
codepoint
is the code point may occur in an identifier, false
if not.
Exemplo #1 Testando codepoints diferentes
<?php
var_dump(IntlChar::isIDPart("A"));
var_dump(IntlChar::isIDPart("$"));
var_dump(IntlChar::isIDPart("\n"));
var_dump(IntlChar::isIDPart("\u{2603}"));
?>
O exemplo acima irá imprimir:
bool(true) bool(false) bool(false) bool(false)
IntlChar::PROPERTY_ID_CONTINUE
