如何將查詢數據放在兩個不同的數組中，然後在兩個表中回顯它？

Question

上table

過濾器運行select query查詢數據

如果gender equal to Man，然後把他所有的數組男性=陣列（），而它的gender is woman然後把

OR

數組woman = array（）

then echo two tables

Men表

1名，年齡，城市，國家等

2名，年齡，城市，國家等

3名，年齡，城市，國家等 。 。 。

Women表

1名，年齡，城市，國家等

2名，年齡，城市，國家等

3名，年齡，城市，國家，等 。 。 。 。

Men表將包含這是保存在Men()陣列

Women表將包含這是保存在Women()陣列

注Woman所有行數據Man所有行數據： -

我嘗試過這樣的代碼，但它的混亂，我失敗了： -

您的查詢必須在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; 

這樣你就可以有一個查詢輸出：後

|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| 

可以循環到你的結果：

<?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(); 
?> 

輸出將如下所示：

//$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' 
     ) 
    );
