Convert UTF-8 to Window 874 using PHP - php

Question

I have encoded string like ªÙªÑ à¾ç§Íé¹
Please check below function that i have used for decode(utf-8 to tis620) it.
function utf8_to_tis620($string) {
$str = $string;
$res = "";
for ($i = 0; $i < strlen($str); $i++) {
if (ord($str[$i]) == 224) {
$unicode = ord($str[$i+2]) & 0x3F;
$unicode |= (ord($str[$i+1]) & 0x3F) << 6;
$unicode |= (ord($str[$i]) & 0x0F) << 12;
$res .= chr($unicode-0x0E00+0xA0);
$i += 2;
} else {
$res .= $str[$i];
}
}
return $res;
}
So it will return string like ชูชัย Gงอ้น but it isn't correct in THAI language.
Actually it should return ชูชัย เพ็งอ้น that is returned from http://string-functions.com/encodedecode.aspx.
But there is used windows 874 decoding.
Please let me know how can i decode utf-8 to windows 874 in php?

Answer 1

You can use mb_convert_encoding to change the character encoding:
function utf8_to_tis620($string) {
return mb_convert_encoding($string, 'UTF-8', 'TIS-620');
}
As noted by krasipenkov in their comment,
There is small difference between ISO-8859-11 and TIS-620. ISO-8859-11 is
nearly identical to the national Thai standard TIS-620 (1990). The
sole difference is that ISO/IEC 8859-11 allocates non-breaking space
to code 0xA0, while TIS-620 leaves it undefined. (In practice, this
small distinction is usually ignored.)
Instead of 'TIS-620', you can use 'ISO-8859-11' for the Windows 874 character encoding if needed.

Answer 2

You can use iconv for convert string to request character encoding.
$string= iconv('TIS-620','UTF-8//ignore',$string);
