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;
}
