StrRev()剂量支持UTF-8 [英] StrRev() Dosent Support UTF-8

问题描述

我正在尝试编写一个代码，以替换不受阿拉伯语支持的程序所支持的阿拉伯语文本
因为替换后我将需要反转文本，但是它显示了一些垃圾内容，而不是所需的结果

I'm trying to make a code that replace Arabic text to be supported in non Arabic supported programs
in that i will be need to reverse the text after replace but its shows some garbage stuff instead of the wanted result

代码在这里:

<?php
$string = "اهلا بك";
echo "$string <br>";
$Reversed = strrev($string);
echo "<br><b>After Reverse</b><br><br>";
echo "<br> $Reversed";
?>

结果:

اهلا بك

After Reverse

我需要它是恢复原样的方式吗?不是垃圾！

I need it to be the way it is but reversed ? not GARBAGE !!

推荐答案

以便使strrev()支持UTF-8 您需要使用此Function

in order to make that strrev() support UTF-8 you need to use this Function

function utf8_strrev($str){
    preg_match_all('/./us', $str, $ar);
    return join('', array_reverse($ar[0]));
}

所以我们要在代码中将strrev()替换为utf8_strev():

so we going to chage strrev() in our code to utf8_strev() :

$string = "اهلا بك";
echo "$string <br>";
$Reversed = utf8_strrev($string); // here we have changed it
echo "<br><b>After Reverse</b><br><br>";
echo "<br> $Reversed";

，结果是:

اهلا بك

After Reverse
