IntlChar::isbase

    (PHP 7, PHP 8)

    IntlChar::isbase — Check if code point is a base character

    Description

    public static IntlChar::isbase(int|string $codepoint): ?bool

    Determines whether the specified code point is a base character. true for general categories "L" (letters), "N" (numbers), "Mc" (spacing combining marks), and "Me" (enclosing marks).

    Note:

    This is different from the Unicode definition in chapter 3.5, conformance clause D13, which defines base characters to be all characters (not Cn) that do not graphically combine with preceding characters (M) and that are neither control (Cc) or format (Cf) characters.

    Parameters

    codepoint

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

    Return Values

    Returns true if codepoint is a base character, false if not. Returns null on failure.

    Examples

    Example #1 Testing different code points

    <?php
    var_dump    (IntlChar::isbase("A"));
    var_dump(IntlChar::isbase("1"));
    var_dump(IntlChar::isbase("\u{2603}"));
    ?>

    The above example will output:

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