I am currently using YouTube's API JSON-C response to pull data from a playlist and display the content in a list. I am doing this using PHP, however because YouTube restricts the maximum number of videos called, I have a hit a stumbling block. The maximum I can request is 50 whereas I have over 200 videos which I need to put in a list and I want to be able to do this dynamically.
I understand that I will have to loop the response, which is what I have done but is there a way it can be dynamically done?
If you could help me that would be great, my code is:
$count = 0;
foreach($data->data->items as $item) {
$count++;
echo $count." ".$item->id;
echo " - ";
echo $item->title;
echo "<br />";
if($count == 50) {
$query = "http://gdata.youtube.com/feeds/api/videos?q=USERNAME&start-index=50&max-results=50&v=2&alt=jsonc";
$data = file_get_contents($query);
if($data){
$data = json_decode($data);
foreach($data->data->items as $item) {
$count++;
echo $count." ".$item->id;
echo " - ";
echo $item->title;
echo "<br />";
}
}
}
if($count == 100) {
$query = "http://gdata.youtube.com/feeds/api/videos?q=USERNAME&start-index=100&max-results=50&v=2&alt=jsonc";
$data = file_get_contents($query);
if($data){
$data = json_decode($data);
foreach($data->data->items as $item) {
$count++;
echo $count." ".$item->id;
echo " - ";
echo $item->title;
echo "<br />";
}
}
}
}
and so on...
If you could help me out, or at least point me in the right direction that would be great, thanks.
One way is to loop over requests, and then over each item in the request. Like this:
Note that
start-index
is 1-based, so you have to query for 1, 51, 101 etc.(This is actually quite similar to reading a file through a buffer, except with a file you've reached the end if the read gives you 0 bytes, while here you've reached the end if you get less than the amount you asked for.)
