I have this program that retrieves videos from a channel and shuffles them, as you can see, the program gets the channel's name from the variable $playlistId
<?php
session_start();
class PlayList {
public function __construct($id) {
$this->id = $id;
$this->videos = [];
$this->currentVideo = 0;
$this->addVideos('https://gdata.youtube.com/feeds/api/users/' . $this->id . '/uploads?v=2&alt=json');
shuffle($this->videos);
}
public function addVideos($url) {
$cont = json_decode(file_get_contents($url));
foreach ($cont->feed->entry as $entry) {
$video = [];
$video['title'] = $entry->title->{'$t'};
$video['desc'] = $entry->{'media$group'}->{'media$description'}->{'$t'};
$video['id'] = $entry->{'media$group'}->{'yt$videoid'}->{'$t'};
$this->videos[] = $video;
}
foreach ($cont->feed->link as $link) {
if ($link->rel === 'next') {
$this->addVideos($link->href);
break;
}
}
}
public function getId() {
return $this->id;
}
public function nextVideo() {
if ($this->currentVideo < count($this->videos) - 1) {
$this->currentVideo += 1;
} else {
$this->currentVideo = 0;
}
}
public function getVideoTitle() {
return $this->videos[$this->currentVideo]['title'];
}
public function getVideoDesc() {
return $this->videos[$this->currentVideo]['desc'];
}
public function getVideoSrc() {
return "http://www.youtube.com/embed/" . $this->videos[$this->currentVideo]['id'];
}
public function printList() {
foreach ($this->videos as $video) {
echo $video['title'] . '<br>';
}
}
}
?>
<?php
$playlistId = "NAKCollection";
if (!isset($_SESSION['playlist']) || $_SESSION['playlist']->getId() != $playlistId) {
$_SESSION['playlist'] = new PlayList($playlistId);
} else {
$_SESSION['playlist']->nextVideo();
}
?>
<html>
<head>
<title>Video Shuffle</title>
</head>
<body>
<div style="float: right;">
<?php
$_SESSION['playlist']->printList();
?>
</div>
<div>
<?php echo $_SESSION['playlist']->getVideoTitle(); ?>
</div>
<div>
<iframe type="text/html" src="<?php echo $_SESSION['playlist']->getVideoSrc(); ?>" allowfullscreen></iframe>
</div>
</body>
</html>
If the channel has like 300 videos the page times out, how can I retrieve 50 videos at a time like a batch and then another 50 when the first group is done?
I know I can alter php.ini but I don't want to do that now
