我的脚本应该输出与用户输入等效的所有数据。

EX 输入 client_id "2"

询问:

msg_id  message  date_sent  client_id

1        a        1/1/1         1  
2        b        2/2/2         1  
3        c        3/3/3         1
4        d        1/2/3         1   
5        e        2/2/2         2    
7        e        2/2/2         2    
8        g        2/2/2         2    
9        f        8/8/8         3

它只会显示

  7        e        2/2/2         2    
  8        g        2/2/2         2

并跳过第一个是

 5        e        2/2/2         2

如果我输入 client_id "3"

不会有输出,但应该显示:

 9        f        8/8/8         3

你能检查我的脚本,看看我在这里做错了什么吗?

你在打电话

$row = $result->fetch_assoc();

在开始循环结果之前:

while ($row = $result->fetch_object()) {
...
}

$row这具有跳过结果集中第一行的效果(因为您从第一次调用开始不做任何事情)。

使用 fetch_assoc() 或 fetch_object()。以下是 PHP 手册中的示例:

$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

if ($result = $mysqli->query($query)) {

    /* fetch associative array */
    while ($row = $result->fetch_assoc()) {
        printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
    }

    /* free result set */
    $result->free();
}

/* close connection */
$mysqli->close();
