IntlChar::getBidiPairedBracket

(PHP 7, PHP 8)

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

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

Maps the specified character to its paired bracket character.

For Bidi_Paired_Bracket_Type!=None, this is the same as IntlChar::charMirror(). Otherwise codepoint itself is returned.

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}")

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 #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) "]"
