有谁知道使用 php 从 Vimeo 嵌入中提取视频 ID 的正则表达式？

Question

有谁知道使用 php 从 Vimeo 标签中提取视频 ID 的正则表达式？

例如：

13084859

来自：

<object width="400" height="225"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=13084859&amp;server=vimeo.com&amp;show_title=1&amp;show_byline=1&amp;show_portrait=0&amp;color=&amp;fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=13084859&amp;server=vimeo.com&amp;show_title=1&amp;show_byline=1&amp;show_portrait=0&amp;color=&amp;fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="400" height="225"></embed></object>

Answer 1

这里：

$html = '<object width="400" height="225"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=13084859&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=13084859&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="400" height="225"></embed></object>';

if (preg_match('/moogaloop\.swf\?clip_id=([0-9]+)/', $html, $matches)) {
  echo $matches[1];
} else {
  echo 'n/a';
}

Answer 2

这是我为您编写的一个简单函数，运行良好，但它不使用正则表达式:)

<?php
function get_vimeo_id( $embed )
{
    $vimeo_id_array = explode( '?clip_id=', $embed );
    $vimeo_id_array_2 = explode( '&', $vimeo_id_array[1] );
    $vimeo_id = $vimeo_id_array_2[0];

    return $vimeo_id;
}

// Get Vimeo Id
$vimeo_id = get_vimeo_id( '<object width="400" height="225"><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="movie" value="http://vimeo.com/moogaloop.swf?clip_id=13084859&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" /><embed src="http://vimeo.com/moogaloop.swf?clip_id=13084859&server=vimeo.com&show_title=1&show_byline=1&show_portrait=0&color=&fullscreen=1" type="application/x-shockwave-flash" allowfullscreen="true" allowscriptaccess="always" width="400" height="225"></embed></object>' );

// Use $vimeo_id
echo $vimeo_id;
?>
