PHP - Best practice to concatenate multiple array values

I want to concatenate some string in this way:

我想以这种方式连接一些字符串:

"string A"
"string B"

my expectation result : "string A \n string B"

And Here my initial array look like this :

在这里,我的初始数组看起来像这样:

array:1 [
  0 => array:2 [
    "foo" => array:1 [
      0 => "string A"
    ]
    "bar" => array:1 [
      0 => "string B"
    ]
  ]
]

What is the best practice for doing this?

这样做的最佳做法是什么?

Seems as though you could use a fairly generic array-flattening function for this:

好像你可以使用相当通用的数组展平函数:

function get_flattened_values($arr, $glue = "\n"){
  $result = array();

  // For each array item in this level of the array
  foreach($arr as $item){

    // If it's the element is an array, recurs and push the result
    if(is_array($item)){
      $result[] = get_flattened_values($item);

    // Else, if it's a string, just push the string
    } else if (is_string($item)){
      $result[] = $item;
    }
  }

  // Join our result together
  return implode($glue, $result);

}

There's two arrays nested in OP's example. So you'll need two loops if you don't pop off the top.

在OP的例子中嵌套了两个数组。所以如果你没有从顶部弹出,你将需要两个循环。

$array1 = array("foo" => "something");
$array2 = array("bar" => "somethingelse");
$result = array_merge($array1, $array2);

//your array here:
$mytest = (array($result));
foreach ($mytest as $key => $value)
{
  foreach($value as $innerItem => $innerValue){
      $str .= ($innerValue);
  }
}

echo($str);
