    IntlChar::getBidiPairedBracket

    (PHP 7, PHP 8)

    IntlChar::getBidiPairedBracket — Get the paired bracket character for a code point

    Description

    public static IntlChar::getBidiPairedBracket(int|string $codepoint): int|string|null

    Maps the specified character to its paired bracket character.

    For IntlChar::PROPERTY_BIDI_PAIRED_BRACKET_TYPE !== IntlChar::BPT_NONE, this is the same as IntlChar::charMirror(). Otherwise codepoint itself is returned.

    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 the paired bracket code point, or codepoint itself if there is no such mapping. Returns null on failure.

    The return type is int unless the code point was passed as a UTF-8 string, in which case a string is returned. Returns null on failure.

    Examples

    Example #1 Testing different code points

    <?php
    var_dump    (IntlChar::getBidiPairedBracket(91));
    var_dump(IntlChar::getBidiPairedBracket('['));
    ?>

    The above example will output:

    int(93)
string(1) "]"
