PHP와 MySQL은 완벽하게 작동하지만 경고를 얻고 있습니다

Question

저는 이것을 알아 내려고 노력해 왔고 Stackoverflow와 다른 사이트를 찾아서 내 문제와 관련이 있습니다.

사람들이 각각의 페이지를 열 때 mysql 테이블을 업데이트하는 PHP 스크립트가 있습니다. 모든 것은 잘 작동합니다 (데이터가 존재하는지 확인하기 위해 각 단계마다 텍스트를 인쇄하도록하고 있습니다. 업데이트는 페이지를 방문하지 않았거나 업데이트하지 않은 경우 URL과 다른 데이터를 테이블에 저장합니다. 방문당 total_votes 및 current_vote. total_votes는 다른 페이지에서 사용되는 통계보고 용이며, current_vote는 매주 값이 감소합니다.

몇 가지 이유로 경고가 표시됩니다. 모든 것이 싫어서 해결할 수없는 경고 및 오류 (최종 결과에 문제가없는 경우에도 마찬가지 임)

데이터베이스가 utf8_general_ci로 설정되어 있으므로 URL 정보가 문제가되지 않아야합니다. .

내가 밖으로의 변화를 방지하기 위해 .. $ first_query에 대한 첫 번째 변수 $ 쿼리를 변경 ... 매개 변수 (1) 부울에서 주어진 mysqli_result 될 것으로 기대하고있다. 루프 내에서 반복적으로 $ query를 사용하면 루프가 혼란스러워집니다.
