PHP를 사용할 때 HTTP 응답의 stange 문자열

Question

내 PHP 코드가 제대로 작동했습니다. 갑자기 응답 데이터에 매우 이상한 문자열이 생겼습니다. 모든 응답 데이터는 아래와 같습니다. "87,0"및 "3e, 0"은 어디에서 왔습니까? 내가 어떻게 그들을 제거 할 수 있습니까? (그들은 표시되기 전에 모든 응답 데이터 후.)

HTTP 서버가 사전에 Content-Length:을 판단 할 수없는 경우, 예를 들어 반대로 출력이 동적 스크립트에 의해 생성 될 때 정적 파일로 출력하면 청크로 출력됩니다 (Transfer-Encoding: chunked 헤더로 표시). 각 청크는 16 진수로 표현 된 길이가 접두사로 붙습니다. 그것들은 당신이 보는 "이상한 끈"입니다. 정확한 세부 사항에서 확인할 수 있습니다
