PHP Manual: Get the paired bracket character for a code point

public static intstringnull IntlChar::getBidiPairedBracket(intstring $codepoint)

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.

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.

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) "]"

Note:
This method is available as of ICU version 52.
