如何合并两种细胞在一个细胞

Question

我有两个具有相同的数据，但拖行只有一个单元不同于其他像这样： -

Customer Name | No Room | Room Type 
Maikle dived   2    single 
Maikle dived   1    double 

所以我不会合并在这样一个小区客户： -

Customer Name | No Room | Room Type 
         2    single 
    Maikle dived    
         1    double 

我如何通过PHP和MySQL

Answer 1

做到这一点。如果你想输出为HTML，然后做以下操作：

//$source should hold the data from DB 
$source = array(
    array('Maikle dived' => array('No Room' => 2, 'Room Type' => 'single'), 
    array('Maikle dived' => array('No Room' => 1, 'Room Type' => 'double'), 
); 

$result = array(); 

foreach($source as $item) { 
    $user = key($item); 
    $val = current($item); 

    if(!isset($result[$user])) { 
     $result[$val] = array(); 
    } 
    $result[$user][] = $val; 
} 

那么你可以遍历$结果建立HTML

foreach($result as $user => $vals) { 
    echo $user; 
    echo '<ul>'; 
    foreach($vals as $val) { 
     echo '<li>'.$val.'</li>'; 
    } 
    echo '</ul>'; 
}
