You can have a look to array_walk_recursive function . This is a working snippet of creating of recursive array to string conversion :

$array = 
  array(
    "1"    => "PHP code tester Sandbox Online",  
    "foo"  => "bar", 
     5 , 
     5     => 89009, 
    "case" => "Random Stuff", 
    "test" => 
       array(
         "test"  => "test221",
         "test2" => "testitem"
       ),
    "PHP Version" => phpversion()
  );

$string="";

$callback = 
  function ($value, $key) use (&$string) {
     $string .= $key . " = " . $value . "\n";
  };

array_walk_recursive($array, $callback);

echo $string;
## 1 = PHP code tester Sandbox Online
## foo = bar
## 2 = 5
## 5 = 89009
## case = Random Stuff
## test = test221
## test2 = testitem
## PHP Version = 7.1.3
