PHP | IntlChar::charMirror() Function

The IntlChar::charMirror() function is an inbuilt function in PHP which is used to find the “mirror-image” character from the given input code point character, which maps the specified character.

Syntax:

mixed IntlChar::charMirror( $codepoint )

Parameters: This function accepts a single parameter $codepoint which is mandatory. The input parameter is a character or integer value, which is encoded as a UTF-8 string.

Return Value: This function returns another Unicode code point that may serve as a mirror-image substitute, or codepoint itself if there is no such mapping or the codepoint does not have the Bidi_Mirrored property. The function returns an integer unless code point was passed in UTF-8 string and a string will be returned.

Below programs illustrate the IntlChar::charMirror() Function in PHP.
Program 1:

<?php
// PHP code to illustrate
// IntlChar::charMirror ()function

// Input Alphabet codepoint character
var_dump(IntlChar::charMirror("A"));
var_dump(IntlChar::charMirror("B"));

// Input codepoint is Symbloic
var_dump(IntlChar::charMirror("&"));
var_dump(IntlChar::charMirror("{"));
var_dump(IntlChar::charMirror("^"));
var_dump(IntlChar::charMirror("]"));

// Input codepoint is integer
var_dump(IntlChar::charMirror("2"));
var_dump(IntlChar::charMirror("10"));

?>

Output:

string(1) "A" 
string(1) "B" 
string(1) "&" 
string(1) "}" 
string(1) "^" 
string(1) "[" 
string(1) "2" 
NULL

Program 2:

<?php
// PHP code to illustrate
// IntlChar::charMirror() function

// Declare an array $arr
$arr = array("G", "Geek", "801", "7", "F", " \\", "/ ", "\t");

// Loop run for every array element
foreach ($arr as $val){

    // Check each element as code point data
    var_dump(IntlChar::charMirror($val));
}
?>

Output:

string(1) "G" 
NULL

string(1) "7" 
string(1) "F"
