Question

我有一个输出以下数据的查询：

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

我需要遍历这个并输出一个类似的结构：

<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>

所以基本上按治疗名称（或ID）进行分组，然后输出与此治疗相关的所有客户。

来自ColdFusion背景我认为使用查询查询等会很容易。但是我一直在努力想出一个PHP解决方案。

我试图做一个while循环，只显示数据，如果treatment_name已经改变，这似乎工作正常，但我不知道如何显示与此相关的customer_types。

有什么想法吗？感谢。

修改以下是使用mysqli_fetch_all从数据库返回的查询的副本：

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)

它以相同的格式继续......

希望这能回答你的问题：

<?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>

您可以使用注释行检查数据并进行相应调整。顺便说一句，这段代码直接将输出打印为html，因此您的浏览器将呈现它。如果您想要内容，请右键单击页面并查看源代码！
