(PHP 7)

IntlChar::isIDPart — Check if code point is permissible in an identifier

Descrição

public static bool IntlChar::isIDPart ( mixed $codepoint )

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().

Parâmetros

Um codepoint integer (por exemplo 0x2603 para U+2603 SNOWMAN), ou um caracter codificado como uma string UTF-8 (exemplo "\u{2603}")

Valor Retornado

Returns TRUE if codepoint is the code point may occur in an identifier, FALSE if not.

Exemplos

<?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)
