IntlChar::getBidiPairedBracket

(PHP 7, PHP 8)

IntlChar::getBidiPairedBracketGet 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 Bidi_Paired_Bracket_Type!=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.

The return type will be int unless the code point was passed as a UTF-8 string, in which case a string will be returned.

范例

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) "]"
