好的我在使用codeIgniter这是我的查询

function get_stories()
{  

   $this->db->from('stories');
   $this->db->join('stories_to_categories', 'stories.id = stories_to_categories.story');
   $this->db->join('categories', 'stories_to_categories.category = categories.id');
   $query = $this->db->get();
   return $query;

)

我正在打印

foreach($story->result() as $row)
{
    echo '
        <tr>
            <td>' . $row->title_english . '</td>
            <td>' . $row->name_english . ',<td>
    ';
}

在我的桌子上我有

1   strategy,   
1   external,   
1   internal,   
1   stakeholder,    
1   crisis,

我尝试实现

1战略，外部，内部，利益相关者，危机，请有人帮我这个吗？

Answer 1

我会使用类似的东西

$results = array();

foreach($story->result() as $row){
  if(!isset($results[$row->title_english]))
    $results[$row->title_english] = array();      
  $results[$row->title_english][] = $row->name_english;    
}

foreach($results as $title_english => $names){
   echo '<tr><td>' . $title_english . '</td><td>' . implode(',',$names) . '</td><tr>';
}

此代码创建另一个（实际上是2维）数组，其中包含由$row->title_english值给出的索引的子数组。遍历初始阵列并填充新阵列后，您可以轻松地以所需格式输出vaules。

Answer 2

尝试在你的foreach中做到这一点：

foreach( $story->result() as $row )
{
    echo '
        <tr>
            <td>' . $row->title_english . '</td>
            <td>' . $row->name_english . ',</td>
        </tr>
    ';
}
