IntlChar::getBidiPairedBracket — Get the paired bracket character for a code point
$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('['));
?>
以上例程会输出：
int(93) string(1) "]"
