IntlChar::getBidiPairedBracket

    (PHP 7, PHP 8)

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

    说明

    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.

    参数

    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}")

    返回值

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

    返回类型是 int，如果代码点作为 UTF-8 string 传递，则会返回 string 。失败时返回 null。

    示例

    示例 #1 Testing different code points

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

    以上示例会输出：

    int(93)
string(1) "]"
