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);

i'm attempting write python 2/3 compatible routine fetch csv file, decode latin_1 unicode , feed csv.dictreader in robust, scalable manner. for python 2/3 support, i'm using python-future including imporing open builtins , , importing unicode_literals consistent behaviour i'm hoping handle exceptionally large files spilling disk, using tempfile.spooledtemporaryfile i'm using io.textiowrapper handle decoding latin_1 encoding before feeding dictreader this works fine under python 3. the problem textiowrapper expects wrap stream conforms bufferediobase . unfortunately under python 2, although have imported python 3-style open , vanilla python 2 tempfile.spooledtemporaryfile still of course returns python 2 cstringio.stringo , instead of python 3 io.bytesio required textiowrapper . i can think of these possible approaches: wrap python 2 cstringio.stringo python 3-style io.bytesio . i'm not sure how approach - need write such wrapper or 1 ex
