PHP：从多维数组中提取值

Question

在这个数组中，我试图从[“member_count”]键提取值int（2128）。

array(3) { 
["total"]=> 
int(1) 
["data"]=> 
    array(1) { 
    [0]=> 
     array(17) { 
     ["id"]=> 
     string(10) "999999999999" 
     ["web_id"]=> 
     int(421097) 
     ["name"]=> 
     string(21) "Name Of List" 
     ["date_created"]=> 
     string(19) "2014-07-14 13:51:01" 
     ["email_type_option"]=> 
     bool(false) 
     ["use_awesomebar"]=> 
     bool(true) 
     ["default_from_name"]=> 
     string(14) "Department Name" 
     ["default_from_email"]=> 
     string(24) "user@email.com" 
     ["default_subject"]=> 
     string(0) "" 
     ["default_language"]=> 
     string(2) "en" 
     ["list_rating"]=> 
     float(3.5) 
     ["subscribe_url_short"]=> 
     string(23) "website/4545" 
     ["subscribe_url_long"]=> 
     string(91) "website" 
     ["beamer_address"]=> 
     string(47) "key goes here" 
     ["visibility"]=> 
     string(3) "pub" 
     ["stats"]=> 
      array(16) { 
      ["member_count"]=> 
       int(2128) 
      ["unsubscribe_count"]=> 
       int(20) 
      ["cleaned_count"]=> 
       int(57) 
      ["member_count_since_send"]=> 
       int(1) 
      ["unsubscribe_count_since_send"]=> 
       int(9) 
      ["cleaned_count_since_send"]=> 
       int(29) 
      ["campaign_count"]=> 
       int(2) 
      ["grouping_count"]=> 
       int(1) 
      ["group_count"]=> 
       int(4) 
      ["merge_var_count"]=> 
       int(6) 
      ["avg_sub_rate"]=> 
       int(17) 
      ["avg_unsub_rate"]=> 
       int(3) 
      ["target_sub_rate"]=> 
       int(17) 
      ["open_rate"]=> 
       float(38.672399892502) 
      ["click_rate"]=> 
       float(14.932747735383) 
      ["date_last_campaign"]=> 
       string(19) "2014-11-07 19:14:30" 
    } 
    ["modules"]=> 
     array(0) { 
    } 
    } 
} 
    ["errors"]=> 
    array(0) { 
    } 
} 

这里是我迄今为止的PHP，但我无法得到公正的价值 “INT（2128）”

foreach($result as $row){ 
    foreach($row[0] as $row1){ 

    echo '<pre>'; 
    var_dump($row1['member_count']); 
    echo '</pre>'; 
    } 
    } 

我得到的结果：

string(1) "6" 

NULL 

string(1) "F" 

string(1) "2" 

NULL 

NULL 

string(1) "B" 

string(1) "d" 

string(0) "" 

string(1) "e" 

NULL 

string(1) "h" 

string(1) "h" 

string(1) "u" 

string(1) "p" 

int(2128) 

NULL 

我非常感谢任何帮助将结果缩小到“int（2128）”的值。

谢谢。

如果只想价值2128使用本：

$array['data'][0]['stats']['member_count'] 

（$数组是你的多维数组的名称）
