如何将查询数据放在两个不同的数组中，然后在两个表中回显它？

Question

上table

过滤器运行select query查询数据

如果gender equal to Man，然后把他所有的数组男性=阵列（），而它的gender is woman然后把

OR

数组woman = array（）

then echo two tables

Men表

1名，年龄，城市，国家等

2名，年龄，城市，国家等

3名，年龄，城市，国家等 。 。 。

Women表

1名，年龄，城市，国家等

2名，年龄，城市，国家等

3名，年龄，城市，国家，等 。 。 。 。

Men表将包含这是保存在Men()阵列

Women表将包含这是保存在Women()阵列

注Woman所有行数据Man所有行数据： -

我尝试过这样的代码，但它的混乱，我失败了： -

您的查询必须在UNION：

Select men.Name, men.age, men.city, men.country, 'Male' as 'gender' FROM men_table as men UNION ALL Select women.Name, women.age, women.city, women.country, 'Female' as 'gender FROM women_table as women; 

这样你就可以有一个查询输出：后

|Name |age |city |country|gender| 
---------------------------------------- 
|male1 |21  |NY  |USA |Male | 
|male2 |23  |CLV |USA |Male | 
|female1|25  |GS  |USA |Female| 
|female2|27  |CHG |USA |Female| 

可以循环到你的结果：

<?php 

$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 men.Name, men.age, men.city, men.country, 'Male' as 'gender' FROM men_table as men UNION ALL Select women.Name, women.age, women.city, women.country, 'Female' as 'gender FROM women_table as women"; 

    $men = array(); 
    $women = array; 

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

     /* fetch associative array */ 
     while ($row = $result->fetch_assoc()) { 
      if($row["gender"] == 'Male') { 
       $men[] = $row[]; 
      } 
      else { 
       $women[] = $row[]; 
      } 
     } 

     print_r($men); 
     print_r($women); 

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

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

输出将如下所示：

//$men array 
    array(
     [0] => array(
       'Name' => 'male1', 
       'age' => '21', 
       'city' => 'NY', 
       'country' => 'USA', 
       'gender' => 'Male' 
     ), 
     [1] => array(
       'Name' => 'male2', 
       'age' => '23', 
       'city' => 'CLV', 
       'country' => 'USA', 
       'gender' => 'Male' 
     ) 
    ); 

//$women array 
    array(
     [0] => array(
       'Name' => 'female1', 
       'age' => '25', 
       'city' => 'GS', 
       'country' => 'USA', 
       'gender' => 'Female' 
     ), 
     [1] => array(
       'Name' => 'female2', 
       'age' => '27', 
       'city' => 'CHG', 
       'country' => 'USA', 
       'gender' => 'Female' 
     ) 
    );
