php - Combining json output from multiple foreach loop -


i have php script returns video streams output. output contains multiple unique streams.

i trying encode output json because of multiple foreach loop not giving proper output

code :

<?php  if (isset($_get["id"]))     $id = $_get["id"]; $temp = explode("=",$id); $link=end($temp);  parse_str(file_get_contents('http://www.youtube.com/get_video_info?video_id='.$link), $video_data); $streams = $video_data['url_encoded_fmt_stream_map']; $streams = explode(',',$streams);  $arr = array();   foreach ($streams $streamdata) {     parse_str($streamdata,$streamdata);     foreach ($streamdata $key => $value) {         $myobj->$key = $value;     }     $arr = $myobj; }  echo json_encode(array("streams"=>$arr)); ?>

above code return last stream/item output.

output : 

{    "streams":{       "quality":"small",       "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\"",       "itag":"17",       "url":"video_link"     } }

if put echo json_encode(array("streams"=>$arr)); inside upper foreach loop. return streams multiple root nodes, , not acceptable. need 1 root node contains steams.

output :

{      "streams":{       "type":"video\/mp4; codecs=\"avc1.64001f, mp4a.40.2\"",       "itag":"22",       "url":"video_link",       "quality":"hd720"     }     }{     "streams":{       "type":"video\/webm; codecs=\"vp8.0, vorbis\"",       "itag":"43",       "url":"video_link",       "quality":"medium"     }     }{     "streams":{       "type":"video\/mp4; codecs=\"avc1.42001e, mp4a.40.2\"",       "itag":"18",       "url":"video_link",       "quality":"medium"     }     }{     "streams":{       "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\"",       "itag":"36",       "url":"video_link",       "quality":"small"     }     }{     "streams":{       "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\"",       "itag":"17",       "url":"video_link",       "quality":"small"     } }

desired output :

{   "streams":[   {      "quality":"hd720",      "itag":"44",      "url":"video_link",      "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\""   },   {      "quality":"medium",      "itag":"",      "url":"video_link",      "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\""   },   {      "quality":"medium",      "itag":"17",      "url":"video_link",      "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\""   },   {      "quality":"medium",      "itag":"17",      "url":"video_link",      "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\""   },   {      "quality":"small",      "itag":"17",      "url":"video_link",      "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\""   },   {      "quality":"small",      "itag":"17",      "url":"video_link",      "type":"video\/3gpp; codecs=\"mp4v.20.3, mp4a.40.2\""   }   ]   }

is there way combing multiple root nodes or json output streams.

note :

  • outer foreach loop iterates 5 times in script lifetime
  • inner foreach loop iterates 4 times per each outer foreach loop in script lifetime

please me new php. tia !!!

tested , got output.

<?php if (isset($_get["id"]))     $id = $_get["id"]; $temp = explode("=",$id); $link=end($temp);  parse_str(file_get_contents('http://www.youtube.com/get_video_info?video_id='.$link), $video_data); $streams = $video_data['url_encoded_fmt_stream_map']; $streams = explode(',',$streams);  $arr = array();   foreach ($streams $streamdata) {     parse_str($streamdata,$streamdata);     $myobj = new stdclass();     foreach ($streamdata $key => $value) {         $myobj->$key = $value;     }     array_push($arr, $myobj); }   print_r (json_encode(array("streams"=>$arr))); ?>

output:
