PHP 파일을 base64로 변환하는 방법

PHP 파일을 base64로 변환하는 방법: 먼저 PHP 샘플 파일을 만든 다음 "fileToBase64($file){...}" 함수를 사용하여 파일을 base64로 변환하고 출력합니다.

php 파일을 base64로 변환하는 방법은 무엇입니까?

base64 출력으로 파일 변환

데이터 URI 체계는 RFC2397에 정의되어 있습니다. 그 목적은 일부 작은 데이터를 웹 페이지에 직접 삽입하여 외부 파일에서 로드할 필요가 없도록 하는 것입니다.

장점: http 연결 수를 줄입니다.

단점: 이 형식의 파일은 브라우저에서 캐시되지 않습니다.

파일이 너무 크면 역효과가 나기 때문에 "20KB를 초과하는" 파일을 인코딩하는 것은 권장되지 않습니다.

data: URI의 기본 사용 형식은 다음과 같습니다.

data:[<MIME-type>][;base64|charset=some_charset],<data>

mime-type은 포함된 데이터의 MIME 유형입니다. 예를 들어 png 이미지는 image/png입니다.

다음에 base64가 오면 다음 데이터가 base64로 인코딩된다는 의미입니다.

데이터 URI 체계는 다음 유형을 지원합니다.

data:,文本数据
data:text/plain,文本数据
data:text/html,HTML代码
data:text/html;base64,base64编码的HTML代码
data:text/css,CSS代码
data:text/css;base64,base64编码的CSS代码
data:text/javascript,Javascript代码
data:text/javascript;base64,base64编码的Javascript代码
data:image/gif;base64,base64编码的gif图片数据
data:image/png;base64,base64编码的png图片数据
data:image/jpeg;base64,base64编码的jpeg图片数据
data:image/x-icon;base64,base64编码的icon图片数据
