IntlChar::isIDPart

(PHP 7)

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

Beschreibung

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).

Hinweis:

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().

Parameter-Liste

codepoint

The integer codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")

Rückgabewerte

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

Beispiele

Beispiel #1 Testing different code points

<?php
var_dump(IntlChar::isIDPart("A"));
var_dump(IntlChar::isIDPart("$"));
var_dump(IntlChar::isIDPart("\n"));
var_dump(IntlChar::isIDPart("\u{2603}"));
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

bool(true)
bool(false)
bool(false)
bool(false)
