PHP 获取视频时长的实例代码

具体代码如下所示：

/*
* 获得视频文件的缩略图和视频长度
* @date 2018-05-16
* @copyright
*/
//获得视频文件的总长度时间和创建时间 根据视频长度判断是否失效
public function gettime($url)
{
  //获取视频重定向后的链接
  $location = locationurl($url);
  //获取视频content-length
  $responsehead = get_data($location);
  $list1 = explode("content-length: ", $responsehead);
  $list2 = explode("connection", $list1[1]);
  $list = explode("x", $list2[0]);
  return $list[0];
}
//获取视频重定向后的链接
function locationurl($url){
  $url_parts = @parse_url($url);
  if (!$url_parts) return false;
  if (!isset($url_parts['host'])) return false;
  if (!isset($url_parts['path'])) $url_parts['path'] = '/';
  $sock = fsockopen($url_parts['host'], (isset($url_parts['port']) ? (int)$url_parts['port'] : '80'), $errno, $errstr, 30);
  if (!$sock) return false;
  $request = "head " . $url_parts['path'] . (isset($url_parts['query']) ? '?'.$url_parts['query'] : '') . " http/1.1\r\n";
  $request .= 'host: ' . $url_parts['host'] . "\r\n";
  $request .= "connection: close\r\n\r\n";
  fwrite($sock, $request);
  $response = '';
  while(!feof($sock)) {
    $response .= fread($sock, 8192);
  }
  fclose($sock);
  if (preg_match('/^location: (.+?)$/m', $response, $matches)){
    if ( substr($matches[1], 0, 1) == "/" ){
      return $url_parts['scheme'] . "://" . $url_parts['host'] . trim($matches[1]);
    }
    else{
      return trim($matches[1]);
    }
  } else {
    return false;
  }
}
//审核视频 curl
function get_data($url){
  $ocurl = curl_init();
  //模拟浏览器
  $header[] = "deo.com";
  $user_agent = "mozilla/4.0 (linux; andro 6.0; nexus 5 build) appleweb/537.36 (khtml, like gecko)";
  curl_setopt($ocurl, curlopt_url, $url);
  curl_setopt($ocurl, curlopt_httpheader,$header);
  curl_setopt($ocurl, curlopt_header, true);
  curl_setopt($ocurl, curlopt_nobody, true);
  curl_setopt($ocurl, curlopt_useragent,$user_agent);
  curl_setopt($ocurl, curlopt_returntransfer, 1 );
  // 不用 post 方式请求, 意思就是通过 get 请求
  curl_setopt($ocurl, curlopt_post, false);
  $scontent = curl_exec($ocurl);
  // 获得响应结果里的：头大小
  $headersize = curl_getinfo($ocurl, curlinfo_header_size);
  // 根据头大小去获取头信息内容
  $header = substr($scontent, 0, $headersize);
  curl_close($ocurl);
  return $header;
}
