如何打印数组中的属性和键值

Question

我需要访问数组的键和属性。我有点困惑，我不知道如何轻松处理。

这是我运行的代码，

foreach ($posts as $key=> $value){ 
    if($value->total_skill!='na'&& $value->total_skill!='0'){ 
     $selcted = $wpdb->get_results("SELECT `$selection` FROM wp_skilllist WHERE First_name = '$value->First_Name' "); 
     var_dump($selcted); 
    } 

我得到下面的结果。我注意到阵列中有很多数组。我需要访问 propeties并打印结果。

举个例子

FMS_Web_tec_HTML   4 

FMS_Web_tec_CSS 3 

FMS_Web_tec_XML 4 

FMS_Web_tec_JavaScript 2 

array (size=1) 
    0 => 
    object(stdClass)[257] 
     public 'FMS_Web_tec_HTML' => string '4' (length=1) 
     public 'FMS_Web_tec_CSS' => string '3' (length=1) 
     public 'FMS_Web_tec_XML' => string '4' (length=1) 
     public 'FMS_Web_tec_JavaScript' => string '2' (length=1) 



array (size=1) 
    0 => 
    object(stdClass)[258] 
     public 'FMS_Web_tec_HTML' => string '3' (length=1) 
     public 'FMS_Web_tec_CSS' => string '3' (length=1) 
     public 'FMS_Web_tec_XML' => string '2' (length=1) 
     public 'FMS_Web_tec_JavaScript' => string '2' (length=1) 


array (size=1) 
    0 => 
    object(stdClass)[257] 
     public 'FMS_Web_tec_HTML' => string '3' (length=1) 
     public 'FMS_Web_tec_CSS' => string '2' (length=1) 
     public 'FMS_Web_tec_XML' => string '3' (length=1) 
     public 'FMS_Web_tec_JavaScript' => string '2' (length=1)

我想你想如果我是正确是不是两个二维数组访问数据$selcted

foreach ($selcted as $sel) { 
    $vars = get_object_vars($sel); 
    foreach ($vars as $key => $var) { 
     echo $sel->$key; 
    } 
}
