检查插入是否成功在循环中执行mysqli_query

Question

我在循环中有一个插入查询，如何检查操作是否完成？

foreach ($_POST['players'] as $value) {
    mysqli_query($conn, "INSERT INTO contactphone(player_id, player_number) VALUES('$value['player_id']','$value['player_number']')");
}

通常对于单次插入，我将执行mysqli_insert_id但在这种情况下我不确定。

您可以将查询执行行包装在if语句中。 如果查询未成功执行，我还添加了一条错误检查行，该行会回显当前实例的错误消息。

foreach ($_POST['players'] as $value) {
if(mysqli_query($conn, "INSERT INTO contactphone(player_id, player_number) VALUES('$value['player_id']','$value['player_number']')") === false){
echo 'error.. The error is '. mysqli_error($conn);
}
}
