查找陣列某一個值，多維數組WordPress的in_array

Question

我運行一個WordPress網站使用WPML這是給我的努力在我翻譯的帖子這是在威爾士CY運行標記的查詢問題負載。

那麼什麼，我試圖做的是一個小黑客，讓我查詢所有帖子，並使用wordpresses功能get_the_tags一個特定的標籤定位後（）;

我想使用in_array這似乎並不給WordPress的輸出，這裏的multidimesional陣列上的工作是從print_r的數組（）;

這裏是我的代碼，我只希望它位於名爲welsh1這是陣列中的最後一個陣列。

// Global calls to the database 
    global $wpdb; 

    // Runs a query to get all results from the wp_posts table 
    $all = $wpdb->get_results("SELECT * FROM wp_posts"); 

    // loops through each one 
    foreach($all as $v){ 

     $tags = get_the_tags($v->ID); 

     if (in_array('welsh1', $tags)) { 
     echo "'ph' was found\n"; 
     } 

     echo "<pre>"; 
     print_r($tags); 
     echo "</pre>"; 
    } 

Answer 1

$ tags是一個對象數組，而不是一個多維數組。

下面的代碼應確定字串welsh1

foreach($tags as $tag){ 
    if ($tag->name == "welsh1" || $tag->slug == "welsh1"){ 
    echo "'ph' was found\n"; 
    break;//this line makes the foreach loop end after first success. 
    } 
}
