如何合併相同的數組鍵，但數值不同。

Question

如何合併相同的數組鍵，但數值不同。 我用我的代碼輸出值如下：

西甲Division2016-17,2017-18國王杯Ray2016-17

但是當我回聲出我的代碼，然後我得到輸出如下：

西甲Division2017-18國王杯Ray2016-17西甲 Division2016-17

你能看兩次西班牙西甲賽區嗎？我想這一次，但這一年兩次。 代碼：

<?php 
     $champion_team = get_post_meta(get_the_ID(), 'football_league_team_name', true); 
     $terms_competition = get_the_terms(get_the_ID(), 'competition'); 
     $terms_session = get_the_terms(get_the_ID(), 'session'); 
     $cc= array_merge($terms_competition, $terms_session); 

     foreach ($cc as $c) { 
     # code... 
     echo $c->name; 
     } 




?> 

print_r的輸出：

Answer 1

只需添加他們

$cc= $terms_competition + $terms_session; 

不存在於$terms_competition中的任何密鑰都是從$terms_session開始添加的。

Answer 2

You can try like this : 
 

 
With array_unique 
 

 
foreach (array_unique($data) as $d) { 
 
// Do stuff with $d ... 
 
}

Answer 3

<?php 
    $champion_team = get_post_meta(get_the_ID(), 'football_league_team_name', true); 
    $terms_competition = get_the_terms(get_the_ID(), 'competition'); 
    $terms_session = get_the_terms(get_the_ID(), 'session'); 
    $cc= array_merge($terms_competition, $terms_session); 

    $temp = array(); 
    foreach ($cc as $c) { 
    # code... 

    if(!in_array($temp)) { 
     echo $c->name; 
     $temp[] = $c->term_id; 
    } 
    }
