Question

我有这个非常困难的数组来迭代。我只想要name索引的值。我已经尝试了很多，但不知道如何找到它。

Array ( [0] => Array ( [created_time] => DateTime Object 
( [date] => 2017-04-01 12:58:25.000000 [timezone_type] => 1 [timezone] =>
+00:00 ) [from] => Array ( [name] => Ghulam Mohe Ud Din [id] => 
1242172779233884 ) [message] => Hi there[id] => 10154774339307663_10154774534942663 ))

以下是我的一些代码练习：

foreach ($getPostlikes as $key=> $item) {//suppose array is $getPostlikes 


    foreach($item as $i)
    {
        echo $i['name'];
    }


}

任何帮助将不胜感激。谢谢

数据：

Array ( 
    [0] => Array ( 
        [created_time] => DateTime Object,
        (
            [date] => 2017-04-01 12:58:25.000000, 
            [timezone_type] => 1, 
            [timezone] => +00:00),
        [from] => Array ( [name] => Ghulam Mohe Ud Din [id] => 1242172779233884 ),
        [message] => Hi there[id] => 10154774339307663_10154774534942663 )
    )

这也将消除重复的名称（每个名称只会显示一次）。

$name_list = array();
foreach($postGetLikes as $postno => $post) {
    if(!isset($name_list[$post['from']['name']])) {
        $name_list[$post['from']['name']] = 0;
    }
    $name_list[$post['from']['name']]++;
}

foreach($name_list as $name => $count) {
    echo $name;
}

Answer 2

$hash = crypt($entered_password,"");
$hash = md5($hash);

如何在PHP中迭代这个多维数组？
