在php中从同一个表运行两个查询

我希望在页面顶部的一个表中显示团队成员及其信息的列表，然后根据其各自行上一个单元格内的值将他们分成团队

“成员”表如下所示：

+------+------------------------+------------------+
| name | interests              | email            |
+------+------------------------+------------------+
| John | Golf, Hockey, Baseball | John@example.com |
| Fred | Hockey                 | Fred@example.com |
+------+------------------------+------------------+

下面是我的代码的简化版本：

$result = mysql_query("SELECT * FROM members");
while($row = mysql_fetch_array($result)){ 
echo "$row['name'] . $row['interests'] . $row['email']"
}

while($row = mysql_fetch_array($result)){
$sport = array($row['interests']);
if (in_array("Golf", $sport)) {
echo "$row['name'] . $row['email']"
}
if (in_array("Hockey", $sport)) {
echo "$row['name'] . $row['email']"
}
if (in_array("Baseball", $sport)) {
echo "$row['name'] . $row['email']"
}

如何使页面看起来像这样？：

全体成员 姓名：约翰
兴趣：高尔夫、曲棍球、棒球
电邮：john@example.com

姓名：弗雷德
兴趣：曲棍球
电邮：fred@example.com

团队
高尔夫球手：
约翰-john@example.com

曲棍球运动员：
约翰-john@example.com
弗雷德-fred@example.com

棒球运动员：

---

约翰-john@example.com

这是未经测试的，但您可以尝试查询所有成员以获取兴趣，然后使用foreach循环遍历每个感兴趣的成员

$result = mysql_query("SELECT * FROM members");
while($row = mysql_fetch_array($result)){ 

$interests =  $row['interests'];

foreach($interests as $interest){
     echo $interest." Players";


      $result = mysql_query("SELECT * FROM members WHERE interests='$interest'");

       while($row = mysql_fetch_array($result)){ 
         $sport = array($row['interests']);
          if (in_array($interest, $sport)) {
             echo "$row['name'] . $row['email']"
          }
       }


   }
}

此代码显示所有成员和团队

 $result = mysql_query("SELECT * FROM members");
 $members=array();
 while($row = mysql_fetch_array($result)){ 
     $members[]=$row;
 }
 echo "All Members:<br>\n";
 foreach($members as $row){
    echo "Name: ".$row['name'] ."<br>Interests: ". $row['interests']."<br>Email:". $row['email']."<br>\n";
 }
 echo "Teams:<br>\n";
 echo "Hockey Players:<br>\n";
 foreach($members as $row){
    if($row['interests']=="Hockey"){
        echo $row['name'] ."-". $row['email']."<br>\n";        
    }
 }
 echo "Golfers Players:<br>\n";
 foreach($members as $row){
    if($row['interests']=="Golfers"){
        echo $row['name'] ."-". $row['email']."<br>\n";        
    }
 }
 echo "Baseball Players:<br>\n";
 foreach($members as $row){
    if($row['interests']=="Baseball"){
        echo $row['name'] ."-". $row['email']."<br>\n";        
    }
 }

$result=mysql\u查询（“从成员中选择*）；
$members=array（）；
而（$row=mysql\u fetch\u数组（$result））{
$members[]=$row；
}
回显“所有成员：
\n”；
foreach（$row成员）{
echo“Name:.$row['Name']。”
兴趣：.$row['Interests']。
电子邮件：.$row['Email']。“
\n”；
}
echo“团队：
\n”；
echo“曲棍球运动员：
\n”；
foreach（$row成员）{
如果（$row['interests']=“曲棍球”）{
echo$row['name']。“-”$row['email']。“
\n”；
}
}
echo“高尔夫球员：
\n”；
foreach（$row成员）{
如果（$row['interests']==“高尔夫球手”）{
echo$row['name']。“-”$row['email']。“
\n”；
}
}
回声“棒球运动员：
\n”；
foreach（$row成员）{
如果（$row['interests']==“ball”）{
echo$row['name']。“-”$row['email']。“
\n”；
}
}

编辑以将兴趣作为一个数组包含，因为可能有多个兴趣

SELECT*FROM members WHERE interest='$interest'

您认为在搜索

棒球时会返回什么？可能您必须在SELECT查询中使用group by name和email。这仅在“兴趣”列。例如，如果（$row['interests']==“Hockey”）{将产生Fred-Fred@example.com但是如果（$row['interests']==“basketball”）{什么也不返回这个工作。它是分四步工作的，首先是所有成员，然后是曲棍球，然后是高尔夫球手，最后是棒球。如果是棒球，最后一步就是展示它
All members
Name: John
Interests: Golf, Hockey, Baseball
E-mail: John@example.com

Name: Fred
Interests: Hockey
E-mail: Fred@example.com

Teams
Golf
John - John@example.com

Hockey
John - John@example.com
Fred - Fred@example.com

Baseball
