如何修整数组以仅显示非重复值？

我与阵列结果挣扎：如何修整数组以仅显示非重复值？

$result = Db::getInstance()->ExecuteS($sql); 

    $this->smarty->assign(array(
     'result' => $result 
    ));

这是我的数组：

Array ( 
[0] => Array ([id_tag] => 2 [id_post] => 5 [id_smart_blog_post_shop] => 5 [id_smart_blog_post] => 5 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
[1] => Array ([id_tag] => 2 [id_post] => 6 [id_smart_blog_post_shop] => 6 [id_smart_blog_post] => 6 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
[2] => Array ([id_tag] => 2 [id_post] => 7 [id_smart_blog_post_shop] => 7 [id_smart_blog_post] => 7 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
[3] => Array ([id_tag] => 2 [id_post] => 8 [id_smart_blog_post_shop] => 8 [id_smart_blog_post] => 8 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
[4] => Array ([id_tag] => 2 [id_post] => 9 [id_smart_blog_post_shop] => 9 [id_smart_blog_post] => 9 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
[5] => Array ([id_tag] => 4 [id_post] => 10 [id_smart_blog_post_shop] => 10 [id_smart_blog_post] => 10 [id_shop] => 1 [id_lang] => 1 [name] => XPPower) 
[6] => Array ([id_tag] => 2 [id_post] => 11 [id_smart_blog_post_shop] => 11 [id_smart_blog_post] => 11 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
[7] => Array ([id_tag] => 2 [id_post] => 12 [id_smart_blog_post_shop] => 12 [id_smart_blog_post] => 12 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
[8] => Array ([id_tag] => 4 [id_post] => 13 [id_smart_blog_post_shop] => 13 [id_smart_blog_post] => 13 [id_shop] => 1 [id_lang] => 1 [name] => XPPower) 
)

和，我要的是显示名称值只有一次这样的：

Microchip, XPPower

而不是这样：

Microchip, Microchip, Microchip, Microchip, Microchip, XPPower, Microchip, Microchip, XPPower

我试图使用array_unique只显示非重复值，但它部分工作，只显示。

Microchip值一次和叶XPPower：

$tags = Db::getInstance()->ExecuteS($sql); 
$result = array_values(array_unique($tags)); 

$this->smarty->assign(array(
    'result' => $result 
));

阵列打印：

Array ( 
[0] => Array ([id_tag] => 2 [id_post] => 5 [id_smart_blog_post_shop] => 5 [id_smart_blog_post] => 5 [id_shop] => 1 [id_lang] => 1 [name] => Microchip) 
)

这是$ SQL函数，如果有人想知道

$sql = 'SELECT * FROM '._DB_PREFIX_.'smart_blog_post_tag p INNER JOIN 
      '._DB_PREFIX_.'smart_blog_post_shop s ON p.id_post=s.id_smart_blog_post AND s.id_shop = '.(int) Context::getContext()->shop->id.' INNER JOIN 
      '._DB_PREFIX_.'smart_blog_tag t ON p.id_tag= t.id_tag where t.id_lang = '.(int)$id_lang.' LIMIT '.$limit;

*我想是为了显示名称值仅一次* - 与那其他列？ – splash58

只有名字值对我来说很重要。其他值不会显示在模块前端 – PipBoy2000

如果你不需要其他值，你可以在你的sql查询中尝试'''GROUP by name'''？ – Ananth

$names = array(); 
foreach ($tags as $tag) { 
    $names[$tag['name']] = 1; 
} 
print_r(array_keys($names));

此代码完美工作，对我的问题100％回答。它破坏了我的聪明变量，但它并没有与这个问题相关联。所以+1我:) – PipBoy2000

无法使用第二个数组捕捉独特的结果？像：

$uniq_results=array(); 
foreach ($results as $r) { 
    if (!in_array($r["name"],$uniq_results)) { 
     $uniq_results[]=$r["name"]; 
    } 
} unset($r); 

var_dump($uniq_results); 
// should print only the unique values
