从YouTube网址获取持续时间 [英] Get duration from a youtube url
问题描述
我正在寻找一种功能,可以从网址中提取视频在YouTube上的播放时间.我读了一些教程,但听不懂.我使用网址将视频嵌入网站中,并且具有拉出缩略图的功能,而我只想获得持续时间的类似内容.这就是我的拇指...
function get_youtube_screen_link( $url = '', $type = 'default', $echo = true ) {
if( empty( $url ) )
return false;
if( !isset( $type ) )
$type = '';
$url = esc_url( $url );
preg_match("|[\\?&]v=([^&#]*)|",$url,$vid_id);
if( !isset( $vid_id[1] ) )
return false;
$img_server_num = 'i'. rand(1,4);
switch( $type ) {
case 'large':
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/0.jpg";
break;
case 'first':
// Thumbnail of the first frame
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/1.jpg";
break;
case 'small':
// Thumbnail of a later frame(i'm not sure how they determine this)
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/2.jpg";
break;
case 'default':
case '':
default:
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/default.jpg";
break;
}
if( $echo )
echo $img_link;
else
return $img_link;
}
您可以使用以下内容:
<?php
function getDuration($url){
parse_str(parse_url($url,PHP_URL_QUERY),$arr);
$video_id=$arr['v'];
$data=@file_get_contents('http://gdata.youtube.com/feeds/api/videos/'.$video_id.'?v=2&alt=jsonc');
if (false===$data) return false;
$obj=json_decode($data);
return $obj->data->duration;
}
echo getDuration('http://www.youtube.com/watch?v=rFQc7VRJowk');
?>
返回视频的时长,以秒为单位.

您可以使用类似此功能的功能将秒更改为小时,分钟和秒. /p>
Im looking for a function that will pull the youtube duration of a video from the url. I read some tutorials but don't get it. I embed videos on my site using a url and I have a function that pulls the thumbnail and I just want something similar that gets the duration. Here's how I get the thumb...
function get_youtube_screen_link( $url = '', $type = 'default', $echo = true ) {
if( empty( $url ) )
return false;
if( !isset( $type ) )
$type = '';
$url = esc_url( $url );
preg_match("|[\\?&]v=([^&#]*)|",$url,$vid_id);
if( !isset( $vid_id[1] ) )
return false;
$img_server_num = 'i'. rand(1,4);
switch( $type ) {
case 'large':
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/0.jpg";
break;
case 'first':
// Thumbnail of the first frame
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/1.jpg";
break;
case 'small':
// Thumbnail of a later frame(i'm not sure how they determine this)
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/2.jpg";
break;
case 'default':
case '':
default:
$img_link = "http://{$img_server_num}.ytimg.com/vi/{$vid_id[1]}/default.jpg";
break;
}
if( $echo )
echo $img_link;
else
return $img_link;
}
You could use something like this:
<?php
function getDuration($url){
parse_str(parse_url($url,PHP_URL_QUERY),$arr);
$video_id=$arr['v'];
$data=@file_get_contents('http://gdata.youtube.com/feeds/api/videos/'.$video_id.'?v=2&alt=jsonc');
if (false===$data) return false;
$obj=json_decode($data);
return $obj->data->duration;
}
echo getDuration('http://www.youtube.com/watch?v=rFQc7VRJowk');
?>
that returns the duration in seconds of the video.

You can use a function like this one to change the seconds to hours, minutes, and seconds.
