我正在尝试将我从Youtube上从特定用户检索到的一堆视频同步到Video Ids的数据库表。
这是因为YouTube不允许向视频添加元信息。因此,我在我的服务器上创建了一个视频表,并希望同步视频。
即。 php / mysql app< - > YouTube的
YouTube视频的数据结构如下:
foreach ($feed as $entry) {
print "<p>";
print $entry->getVideoId();
print "</p>";
}
对于我的数据库是这样的:
$rs->MoveFirst();
while (!$rs->EOF) {
print "<p>";
print $rs->fields['yt_id'];
print "</p>";
$rs->MoveNext();
}
您知道如何同步这些数据,以便:
答案 0 :(得分:1)
从两个位置获取ID后,您可以使用array_diff()
来比较ID,例如:
//build array of video IDs in YouTube
$arYT = array();
foreach ($feed as $entry) {
$arYT[] = $entry->getVideoId();
}
//build array of video IDs in local DB
$arDB = array();
$rs->MoveFirst();
while (!$rs->EOF) {
$arDB[] = $rs->fields['yt_id'];
$rs->MoveNext();
}
//to download, we want IDs which are in YouTube but not in the local Db
$idsToDownload = array_diff($arYT, $arDB);
//to delete, we want IDs which are in the local DB but not in YouTube
$idsToDelete = array_diff($arDB, $arYT);
然后你可以这样做:
//download new videos
foreach ($idsToDownload as $id) {
//get video info for video $id and put into local db
}
//delete deleted videos
foreach ($idsToDelete as $id) {
//delete $id from local DB
}
