utf8-decode는 8.2부터 DEPRECATED 되므로 아래와 같은 변환방식을 이용하시면 됩니다.
https://www.php.net/manual/en/function.mb-convert-encoding.php
-----------------------------
<?php
/* Convert internal character encoding to SJIS */
$str = mb_convert_encoding($str, "SJIS");
/* Convert EUC-JP to UTF-7 */
$str = mb_convert_encoding($str, "UTF-7", "EUC-JP");
/* Auto detect encoding from JIS, eucjp-win, sjis-win, then convert str to UCS-2LE */
$str = mb_convert_encoding($str, "UCS-2LE", "JIS, eucjp-win, sjis-win");
/* If mbstring.language is "Japanese", "auto" is expanded to "ASCII,JIS,UTF-8,EUC-JP,SJIS" */
$str = mb_convert_encoding($str, "EUC-JP", "auto");
?>
