PHP - подсчет строк в массиве

Question

Кто-нибудь знает, как получить количество вхождений «фото» и «статус»? Я попытался вывести его как строку и выполнить substr_count, но не повезло.

Array ([0] => [1] => photo) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => status) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => status) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => status) 
Array ([0] => [1] => status) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => status) 
Array ([0] => [1] => status) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => status) 
Array ([0] => [1] => status) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => photo) 
Array ([0] => [1] => status) 
Array ([0] => [1] => status) 
Array ([0] => [1] => status) 
Array ([0] => [1] => link) 
Array ([0] => [1] => status) 

оригинальный JSON код из API Facebook Graph является:

      } 
     ], 
     "count": 9 
     }, 
     "is_published": true 
    }, 

я выполняю json_decode с выходом JSON, а затем проходным, как эти данные

Еогеасп ($ page_posts_overview-> в $ page_posts_overview_output) {

$type = " ".$page_posts_overview_output->type; 
$type = explode(" ", $type); 

$type = array($type); 

print_r ($type);// this is what the output posted above 

}

Answer 1

Я думаю, что вы должны были бы перебрать массив вручную и сохранить подсчет количества раз каждое слово показывает вверх:

function count_words($fb_array) { 

    $keywords = array(); 

    foreach($fb_array as $element) { 
    $word = $element[1]; 
    if (!array_key_exists($keywords, $word)) { 
     $keywords[$word] = 0; 
    } 
    $keywords[$word]++; 
    } 

    return $keywords; 
} 

print_r($keywords); 

Если у вас есть массив ключевых слов в $fb_array, $keywords теперь должен содержать счетчик для каждого слова.

Answer 2

$a = array(...); // your Facebook data 
$b = array(); 
foreach ($a as $e) { 
    $b[] = $e[1]; 
} 
$c = array_count_values($b); 
var_dump($c)
