循環執行連接查詢

Question

我有一個查詢，它輸出以下數據：

Treatment ID --------- Treatment_Name ---------- Customer_type 
1      Treatment 1    Ladies 
1      Treatment 1    Mens 
3      Treatment 2    Ladies 
4      Treatment 3    Mens 

我需要循環這個輸出的結構類似於此：

<div class="mens ladies"> <!-- these are read from the customer_type column --> 
    <h4>Treatment 1</h4> <!-- this is read from the treatment_name column --> 
</div> 

所以基本上分組通過治療名稱（或ID），然後輸出所有與這種治療有關的顧客。

來自ColdFusion背景我認​​爲這將很容易與查詢查詢等，但我一直在努力提出一個PHP解決方案。

我試着做一個while循環，只顯示數據，如果治療名稱已更改似乎工作正常，但我不知道如何顯示與此相關的customer_types。

任何想法？謝謝。

編輯 下面是一個使用mysqli_fetch_all從數據庫返回的查詢的副本：

array (size=22) 
    0 => 
    array (size=3) 
     0 => string 'Mens' (length=4) 
     1 => string '1' (length=1) 
     2 => string 'treatment 1' (length=11) 
    1 => 
    array (size=3) 
     0 => string 'Ladies' (length=6) 
     1 => string '1' (length=1) 
     2 => string 'treatment 1' (length=11) 
    2 => 
    array (size=3) 
     0 => string 'Kids' (length=4) 
     1 => string '2' (length=1) 
     2 => string 'treatment 2' (length=11) 
    3 => 
    array (size=3) 
     0 => string 'Ladies' (length=6) 
     1 => string '2' (length=1) 
     2 => string 'treatment 2' (length=11) 
    4 => 
    array (size=3) 
     0 => string 'Mens' (length=4) 
     1 => string '2' (length=1) 
     2 => string 'treatment 2' (length=11) 
    5 => 
    array (size=3) 
     0 => string 'Mens' (length=4) 
     1 => string '3' (length=1) 
     2 => string 'treatment 3' (length=11) 
    6 => 
    array (size=3) 
     0 => string 'Kids' (length=4) 
     1 => string '3' (length=1) 
     2 => string 'treatment 3' (length=11) 
    7 => 
    array (size=3) 
     0 => string 'Ladies' (length=6) 
     1 => string '3' (length=1) 
     2 => string 'treatment 3' (length=11) 
    8 => 
    array (size=3) 
     0 => string 'Ladies' (length=6) 
     1 => string '4' (length=1) 
     2 => string 'treatment 4' (length=11) 

它繼續以同樣的格式...

希望這回答了你的問題：

<?php 
    $link = mysqli_connect("hostname","username","password","database","port") or die("Error " . mysqli_error($link)); 
    $query = "SELECT treatment_name,Customer_type from Treatments" or die("Error at.." . mysqli_error($link)); 
    $result = $link->query($query); 

    while($row = mysqli_fetch_assoc($result)) { 
     $data[] = $row; 
    } 
//I have used this sample array: Try and make your result set this way 
    $data = array(
       array('treatment_name'=>'Treatment1','Customer_type'=>'Mens'), 
       array('treatment_name'=>'Treatment1','Customer_type'=>'Ladies'), 
       array('treatment_name'=>'Treatment2','Customer_type'=>'Mens') 
      ); 
    foreach ($data as $key => &$value) { 
     $temp[$value['treatment_name']][$key] = $value['Customer_type']; 
    } 

    //echo "<pre>"; 
    //print_r($data); 
    //print_r($temp); 
    //die; 

    foreach($temp as $key => $value){ 
     echo "<div class = \""; 
     foreach($value as $key2 => $value2) 
      echo " ". $value2. " "; 
     echo "\"><h4>".$key."</h4></div></br>"; 
    }    
?> 
//Output 
<div class = " Mens Ladies "><h4>Treatment1</h4></div></br><div class = " Mens "><h4>Treatment2</h4></div></br> 

您可以使用註釋行來檢查數據並進行相應調整。 順便說一下，這段代碼直接打印輸出爲html，所以你的瀏覽器會渲染它。如果您想要內容，請右鍵單擊頁面並查看源代碼！
