找到数组键值并将其与关键字相同

Question

Array (
    [Name] => Amjad Khan 
    [percentage] => 70.0 
    [Hobbies] => Array ( 
        [0] => reading 
        [1] => cricket 
        [2] => football 
        [3] => hockey
    ) 
) 

我有上面的数组。

我需要过滤[爱好]，如

[Hobbies]=>reading,cricket,football,hockey

爱好关键是动态而不是静态

Answer 1

不完全确定你想要什么，但试试这个：

$key = 'Hobbies';
$array[$key] = implode(',', $array[$key]);

Answer 2

使用implode功能

$arr = Array ( 'Name' => "Amjad Khan", 'percentage' => 70.0 ,'Hobbies' => Array ('reading','cricket','football','hockey' ) );
print_r($arr['Hobbies']);
$new = implode(',',$arr['Hobbies']);
echo $new;

Answer 3

试试这个!!!!!!!!!!!!!!!!!

   "Name" => Amjad,

   "percentage" => 70.0,

    "Hobbies" => array (
    "0" => reading,

     "1" => cricket, 

   "2" => football

    )         

  );



 foreach ($arr as $key => $value) {

  if($key == Hobbies){


 $arr[Hobbies] = implode(',',$value);

  }

       }

  echo '<pre>';

  print_r($arr);

Answer 4

您可以检查是否存在爱好键，然后将其值内爆：

if (isset($array['Hobbies'])) {
    $array['Hobbies'] = implode(',', $array[$key]);
}
