mysqli_get_connection_stats() 함수는 클라이언트 연결의 통계 데이터를 반환합니다
mysqli_get_connection_stats()함수는 연결 객체를 파라미터로 받아 주어진 연결의 정보를 배열 형태로 검색하고 반환합니다/상태. 이 함수는 오직mysqlnd에서 등장했습니다.
mysqli_get_connection_stats($con);
순번 | 파라미터 및 설명 |
---|---|
1 | con(선택적) 이는 MySQL Server와의 연결을 나타내는 객체입니다. |
PHP mysqli_get_connection_stats() 함수는 배열을 반환하며, 주어진 연결의 상태 정보를 포함하고 있습니다. 실패할 경우, 이 함수는 부울 값을 반환합니다.false에서 등장했습니다.
이 함수는 초기로 PHP 버전5그리고 모든 더 높은 버전에서 사용할 수 있습니다.
다음 예제는 다음에서 표시된 것을 설명합니다.mysqli_get_connection_stats()함수의 사용법(정의 절적 스타일)-
<?php //연결 설정 $con = mysqli_connect("localhost", "root", "password", "mydb"); //연결 상태 $stat = mysqli_get_connection_stats($con); print_r($stat); //연결 닫기 mysqli_close($con); ?>
