PHP 확장 메서드가 반환되지 않습니다 이유는 무엇입니까?

다음은 php_ex.cc입니다. .so 라이브러리를 컴파일 할 때 retur() 메소드가 작동하지 않습니다. 왜? 나는 오류가 없지만 "test"를 인쇄해야하고 그렇지 않다. t. 내가 그 클래스의 자동차를 언급하고 싶습니다이 방법은 작업의

Answer 1

retur 메서드가 실제로 stdout에 쓰는 경우 일반적으로 PHP의 출력은 stdout과 일치하지 않습니다.

CLI SAPI의 경우 (예를 들어), PHP의 출력 버퍼링을 거치지 않고 stdout에 직접 쓰면됩니다.

대신 php_printf 또는 PHPWRITE을 사용해야합니다.
