陣列匹配只有一個結果

Question

是否有可能實現此目的？

我有一些陣列

Array 
(
    [1] => Model_Like Object 
     (
      [_is_new:protected] => 
      [_frozen:protected] => 
      [_data:protected] => Array 
       (
        [id] => 1 
        [user_id] => 5 
        [liked_by] => 1 
       ) 

      [_custom_data:protected] => Array 
       (
       ) 

      [_original:protected] => Array 
       (
        [id] => 1 
        [user_id] => 5 
        [liked_by] => 1 
       ) 

      [_data_relations:protected] => Array 
       (
       ) 

      [_original_relations:protected] => Array 
       (
       ) 

      [_reset_relations:protected] => Array 
       (
       ) 

      [_view:protected] => 
      [_iterable:protected] => Array 
       (
       ) 

     ) 

    [2] => Model_Like Object 
     (
      [_is_new:protected] => 
      [_frozen:protected] => 
      [_data:protected] => Array 
       (
        [id] => 2 
        [user_id] => 5 
        [liked_by] => 2 
       ) 

      [_custom_data:protected] => Array 
       (
       ) 

      [_original:protected] => Array 
       (
        [id] => 2 
        [user_id] => 5 
        [liked_by] => 2 
       ) 

      [_data_relations:protected] => Array 
       (
       ) 

      [_original_relations:protected] => Array 
       (
       ) 

      [_reset_relations:protected] => Array 
       (
       ) 

      [_view:protected] => 
      [_iterable:protected] => Array 
       (
       ) 

     ) 

    [4] => Model_Like Object 
     (
      [_is_new:protected] => 
      [_frozen:protected] => 
      [_data:protected] => Array 
       (
        [id] => 4 
        [user_id] => 5 
        [liked_by] => 6 
       ) 

      [_custom_data:protected] => Array 
       (
       ) 

      [_original:protected] => Array 
       (
        [id] => 4 
        [user_id] => 5 
        [liked_by] => 6 
       ) 

      [_data_relations:protected] => Array 
       (
       ) 

      [_original_relations:protected] => Array 
       (
       ) 

      [_reset_relations:protected] => Array 
       (
       ) 

      [_view:protected] => 
      [_iterable:protected] => Array 
       (
       ) 

     ) 

) 

，我只想要壽顯示一個匹配的結果。

<?php foreach ($user->likes as $likes): ?> 
<?php if($likes['liked_by'] == $logged_in_user_id): ?> 
    <?php echo "you like it" ?> 
<?php else: ?> 
    <?php echo "you dont like it" ?> 
<?php endif; ?> 
<?php endforeach; ?> 

和這樣我得到下面的結果

you like it you dont like it you dont like it 

有沒有去，只顯示結果相配套？

Answer 1

使用return;從環

<?php 
    $result = "you dont like it"; 
    foreach ($user->likes as $likes) { 
    if($likes['liked_by'] == $logged_in_user_id) { 
     $result = "you like it"; 
    } 
    } 
    echo $result; 
?> 

Answer 2

當你打比賽時，你可以跳出循環。有多種方法可以實現這一點，從使用標記變量來打破對比賽的控制流程。

Answer 3

或者跳出來，你可以過濾喜歡陣列只包含用戶的喜歡。之後，你只需要獲取該數組的第一個條目，這是第一個「like」。爲了給你一個印象：

$likesOfUser = array_filter($user->likes, function($c) use ($logged_in_user_id) 
{ 
    return $c['liked_by'] == $logged_in_user_id; 
}); 

$like = array_shift($likesOfUser); 

但是，這也許是有點潔癖，只推薦，如果你需要喜歡反正在一個單獨的陣列。
