问题描述
我有一组youtube iframe /对象，如下所示：
I have an array of youtube iframes/objects like so:
[0] => <iframe width="600" height="338" src="http://www.youtube.com/embed/szL_PVuzWp0?fs=1&feature=oembed" frameborder="0" allowfullscreen></iframe>
[1] => <object width="600" height="338"><param name="movie" value="http://www.youtube.com/v/jm1S43a-e3Y?version=3&feature=oembed"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/jm1S43a-e3Y?version=3&feature=oembed" type="application/x-shockwave-flash" width="600" height="338" allowscriptaccess="always" allowfullscreen="true"></embed></object>
[2] => <iframe width="600" height="338" src="http://www.youtube.com/embed/7fTploFSbXA?fs=1&feature=oembed" frameborder="0" allowfullscreen></iframe>
[3] => <iframe width="600" height="338" src="http://www.youtube.com/embed/vQSRNYgiuMk?fs=1&feature=oembed" frameborder="0" allowfullscreen></iframe>
请注意，嵌入方法可能有所不同（通常< iframe> ，偶尔< object> ）（由于外部数据源）。
Note that the embed method can vary (usually <iframe>, occasionally <object>) (due to external data source).
我/ /最可靠的方法是为每个人提取视频网址（例如vQSRNYgiuMk或jm1S43a-e3Y）？
How would I/what is the most reliable method to go about extracting the video URL (e.g. vQSRNYgiuMk or jm1S43a-e3Y) for each one?
最终我想要结束一个数组如下：
Ultimately I want to end up with an array like so:
[0] => "szL_PVuzWp0"
[1] => "jm1S43a-e3Y"
[2] => "7fTploFSbXA"
[3] => "vQSRNYgiuMk"
推荐答案
foreach($arr as $i=>$a){
$start = strpos($a, "/v/") + 3;
if(!$start) $start = strpos($a, "/embed/") + 7;
$qm = strpos("?");
$length = $qm - $start;
$new_array[$i] = substr($a, $start, $length);
}
