either use array_walk_recursive() function or write own function recursively traverse array , print urls.

suppose $arr array.

method(1):

array_walk_recursive($arr, function($item, $key) {     if ($key == "href") {         echo $item . "<br />";     } }); 

method(2):

function process_array($array){     foreach($array $key => $value){         if(is_array($value)){             process_array($value);         }else{             if($key == "href"){                 echo $value . "<br />";             }         }     } }  process_array($arr);
