php - 数组不输出所有值

Question

我有一个小问题，我似乎无法解决。我有一些数据从数据库中提取，在显示数据之前，我想操纵一些数据。这里是我的功能处理这些：

public function getPageContent($id) 
{ 
    $menutopic_model = new Menu_Topic(); 
    $content = $menutopic_model->getAllContent($id); 

    //var_dump($content);   

    $data = array(); 

    foreach ($content as $value) 
    { 
     $title = explode(',', $value->title); 
     $filename = explode(',', $value->filename); 

     $data['topicname'] = $value->topicname; 
     $data['title'] = $title; 
     $data['filename'] = $filename; 

    }  

    //var_dump($data); 

} 

现在，当我倾倒var_dump($content);，我得到的数据的整个数组，它应该是：

array(2) { 
    [0]=> 
    object(stdClass)#346 (3) { 
     ["topicname"]=> 
     string(19) "Signs giving orders" 
     ["title"]=> 
     string(42) "Stop,No entry,No cycling,No motor vehicles" 
     ["filename"]=> 
     string(179) "DQP0GVcUA2dG8ZfqeVYLO68YodgYnJMOjJw2o2iC.png,vWUcHGX3VVKPT08JXh9mAqZ40pT0vfDJ78Yoqovz.png,bplX8bbwHzHKX9n6SvvQiYNhkWwKxi2bhsrQ94U2.png,8KAEovxQn3EgzHoZg1euSgNYTFupnLdKusJ4SIEP.png" 
    } 
    [1]=> 
    object(stdClass)#345 (3) { 
     ["topicname"]=> 
     string(13) "Warning Signs" 
     ["title"]=> 
     string(111) "Road narrows ahead both sides,Road narrows on right (left if symbol reversed),Crossroads,Junction on bend ahead" 
     ["filename"]=> 
     string(179) "uZ7fnDjlYfKU3pdSQ7wAq4siFryA6jSEitmRyPhp.png,4pslo6cC0I2E606DscWxiDD3sCBW7ZGaESQES4r0.png,xdVBMpV6PTLtX48M67kfWOqy59rsYMDZMuWbqDwl.png,hLtIGikARgARqmSqit4mqNXRFJthipH6O5vqxlbN.png" 
    } 
    } 

而是通过在foreach传递数据之后，这var_dump($data);仅返回数组中的最后一项：

array(3) { 
    ["topicname"]=> 
    string(13) "Warning Signs" 
    ["title"]=> 
    array(4) { 
    [0]=> 
    string(29) "Road narrows ahead both sides" 
    [1]=> 
    string(47) "Road narrows on right (left if symbol reversed)" 
    [2]=> 
    string(10) "Crossroads" 
    [3]=> 
    string(22) "Junction on bend ahead" 
    } 
    ["filename"]=> 
    array(4) { 
    [0]=> 
    string(44) "uZ7fnDjlYfKU3pdSQ7wAq4siFryA6jSEitmRyPhp.png" 
    [1]=> 
    string(44) "4pslo6cC0I2E606DscWxiDD3sCBW7ZGaESQES4r0.png" 
    [2]=> 
    string(44) "xdVBMpV6PTLtX48M67kfWOqy59rsYMDZMuWbqDwl.png" 
    [3]=> 
    string(44) "hLtIGikARgARqmSqit4mqNXRFJthipH6O5vqxlbN.png" 
    } 
} 

我应该在上面更改哪个以获得正确结果？

Answer 1

您每次循环都重复使用相同的数组。因此，创建数组，然后ASA新的次数将其添加到真正的阵列

public function getPageContent($id) 
{ 
    $menutopic_model = new Menu_Topic(); 
    $content = $menutopic_model->getAllContent($id); 

    //var_dump($content);   

    foreach ($content as $value) 
    { 
     $title = explode(',', $value->title); 
     $filename = explode(',', $value->filename); 

     $d = array(); 
     $d['topicname'] = $value->topicname; 
     $d['title'] = $title; 
     $d['filename'] = $filename; 

     $data[] = $d; 
    }  

    //var_dump($data); 

} 

Answer 2

你都拿到刚刚因为你在下面的代码，您所使用的阵列上写入值最后一个值。

$data['topicname'] = $value->topicname; 
$data['title'] = $title; 
$data['filename'] = $filename; 

更改代码：

public function getPageContent($id) 
{ 
    $menutopic_model = new Menu_Topic(); 
    $content = $menutopic_model->getAllContent($id);  

    $data = array(); 

    foreach ($content as $value) 
    { 
     $title = explode(',', $value->title); 
     $filename = explode(',', $value->filename); 

     $data[]=array(
      'topicname'=>$value->topicname, 
      'title'=>$title, 
      'filename'=>$filename); 
    }  

    //var_dump($data); 

}
