Number to utf-8 unicode converting using php

Question

Actually my expected result was- zero ০ one ১ two ২ three ৩ four ৪ five ৫ six ৬ seven ৭ eight ৮ nine ৯

But I got- zero &#ý৯;ý৯;3৭;৬;ý৯;ý৯;3৭;ý৯;3৮;; one &#ý৯;ý৯;3৭;৬;ý৯;ý৯;3৭;ý৯;;
two ý৯;ý৯;3৭;৬;
three ý৯;3৭;
four ý৯;3৮;
five ý৯;
six ৬
seven ৭
eight ৮
nine ৯ pleas help me. The code:

$n=array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9');

 $x=array("&#2534;", "&#2535;", "&#2536;", "&#2537;", "&#2538;", "&#2539;", "&#2540;", "&#2541;", "&#2542;", "&#2543;");

$on='O 0
 one 1
 two 2
 three 3
 four 4
 five 5
 six 6
 seven 7
 eight 8
 nine 9';

 $converted = nl2br(str_replace($n, $x, $on));


 echo $converted;

why not serve your page with a content-type encoding of UTF-8 and use the actual characters instead of the entities? — Gordon
I've added <meta http-equiv="content-type" content="text/html; charset=utf-8;"> in <head> but the same result returned. — user2056034
meta tags are only used then server does not serve appropriate headers. Either set the content via php.net/headers or check your webserver configuration. — Gordon

str_replace is not encoding-safe. you have an implementation of a multibyte str_replace ( mb_str_replace ) here :

function mb_str_replace($needle, $replacement, $haystack)
{
    $needle_len = mb_strlen($needle);
    $replacement_len = mb_strlen($replacement);
    $pos = mb_strpos($haystack, $needle);
    while ($pos !== false)
    {
        $haystack = mb_substr($haystack, 0, $pos) . $replacement
                . mb_substr($haystack, $pos + $needle_len);
        $pos = mb_strpos($haystack, $needle, $pos + $replacement_len);
    }
    return $haystack;
}

Edit: Oups, your characters are HTML encoded, not a PHP encoding problem.
