문자셋 - UTF-8, EUC-KR / 인코딩 변경 - 언어셋

■ UTF-8 을 EUC-KR 로 변경
$str = iconv("UTF-8", "EUC-KR", $str);
 
■ EUC-KR 을 UTF-8 로 변경
$str = iconv("EUC-KR", "UTF-8", $str);

■ %?? 형태로 변환
$str = urlencode($str);
$str = urldecode($str);

■ 한글 이미지 뜨지 않을때 해결 본 소스
$str = iconv("UTF-8", "EUC-KR", $str);
$str = urlencode($str);
 
※ 글자수 기준으로 substr() 함수를 자를 때 참고사항
EUC-KR 에서 한글은 2 byte
UTF-8 에서 한글은 3 byte
