    IntlChar::isgraph — Check if code point is a graphic character

    Description

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

    Determines whether the specified code point is a "graphic" character (printable, excluding spaces).

    true for all characters except those with general categories "Cc" (control codes), "Cf" (format controls), "Cs" (surrogates), "Cn" (unassigned), and "Z" (separators).

    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 "graphic" character, false if not. Returns null on failure.

    Examples

    Example #1 Testing different code points

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

    The above example will output:

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