最近购买了带有macOS Sierra的Macbook Pro，并安装了XAMPP版本7.0.31。

开启MYSQL，ProFTPD和Apache Web Server之后，当我打开phpmyadmin时注意到了一些东西。

下面说了一个错误：

The $cfg['TempDir'] (./tmp/) is not accessible. phpMyAdmin is not able to cache templates and will be slow because of this.

我如何打开这个数组：

$details = ["Dog" => "Natahlia", "Cat" => "Ryan", "Bird" => "Natahlia"];

到此（所需的输出）：

$details = [["Natahlia"=>["Dog","Bird"], "Ryan"=>"Cat"];

由于我的代码连接了值或覆盖了值，因此遇到了一些麻烦。

$arr = array();
foreach($details as $key => $value){
   if(array_key_exists($value,$arr)){
      //this part i dont know what to do since += wont do it since it's a string and .= concatenates it
      $arr[$value] = $key;
   } else {
      $arr[$value] = $key;
   }
}
return $arr;
