[펌] JPEG EXIF 정보 얻는 함수(read_exif_data 사용 안함)
JPEG의 이미지 metadata 정보를 얻어오는 클래스 라이브러리 입니다.
PHP에서 제공하는 exif관련 함수를 전혀 사용하지 않고 hexData를 분석하여 추출해 내므로 별도의 EXIF 관련 외부 라이브러리를 설치하지 않으셔도 이용하실 수 있습니다.
사용하는 법은 아래와 같습니다.
<?php
$exif = new exif('image.jpg');
print_r($exif ->getImageInfo());
?>
exif::exif() 함수로 읽어올 이미지 파일을 설정한후
exif::getImageInfo() 함수로 해당 이미지의 EXIF 및 기타 모든 정보를 리턴받습니다.
- 클래스 설명
- exif class
＊exif::exif("(string)파일경로", "(string)언어설정(en|ko)", "(boolen)디버그 정보 출력여부");
＊exif::getImageInfo(void);
라이센스는 기본 MIT 을 따릅니다.
