分组结果和排序输出

Question

用下面的代码：

$result3 = mysql_query("SELECT TIP,GRUPA FROM test1 GROUP BY GRUPA,TIP ORDER BY GRUPA ASC, TIP ASC") or die(mysql_error()); 
$group = null; 
while($row = mysql_fetch_array($result3)) 
{ 
    if($row['GRUPA'] != $group) 
    { 
     echo $row['GRUPA']."<br />"; 

     $group = $row['GRUPA']; 

    } 

    echo $row['TIP']."<br />"; 

} 

它告诉我的结果是这样的：

FRUITS 
apples 
pears 
....... 
VEGETABLES 
onion 
carrot 
....... 

但是，我想显示的结果是这样的：

apples 
pears 
........ 
FRUITS 
onion 
carrot 
........ 
VEGETABLES 

如何更改代码？

Answer 1

尝试这样的事情，并告诉我从print_r的）结果（:)

$new_arr = array(); 
    $group = null; 
    while($row = mysql_fetch_array($result3)) 
    {  
     if($row['GRUPA'] != $group) 
     { 
      $new_arr[$row['GRUPA']] = array(); 
      $group = $row['GRUPA']; 
     } 

     array_push($new_arr[$group], $row['TIP']); 
    } 

    echo "<pre>"; 
    print_r($new_arr); 
    echo "</pre>"; 

然后更换：

echo "<pre>"; 
print_r($new_arr); 
echo "</pre>"; 

有：

foreach($new_arr as $ar => $vals) 
{ 
    foreach ($vals as $val) 
    { 
     echo $val.'<br />'; 
    } 
    echo $ar.'<br /><br/>'; 
}
