How can I detect video file duration in minutes with PHP?
提问by Evan Lévesque
I am trying to detect the duration of any video file before it is uploaded with PHP
so if it is less than one minute for example I will refuse uploading it.
if it is not possible , how can I do it after uploading the video ??
我试图在使用 PHP 上传任何视频文件之前检测它的持续时间，
因此如果它少于一分钟，例如我将拒绝上传它。
如果不可能，上传视频后我该怎么做？？

You can get video durationwith ffmpegor getID3
您可以video duration使用ffmpeg或 getID3
Example
例子
$getID3 = new getID3;
$file = $getID3->analyze($filename);
echo("Duration: ".$file['playtime_string'].
" / Dimensions: ".$file['video']['resolution_x']." wide by ".$file['video']['resolution_y']." tall".
" / Filesize: ".$file['filesize']." bytes<br />");
Or
或者
ob_start();
passthru("ffmpeg -i working_copy.flv 2>&1");
$duration = ob_get_contents();
$full = ob_get_contents();
ob_end_clean();
$search = "/duration.*?([0-9]{1,})/";
print_r($duration);
$duration = preg_match($search, $duration, $matches, PREG_OFFSET_CAPTURE, 3);
print_r('<pre>');
print_r($matches[1][0]);
print_r($full);

first download the latest version from the first link above in the accepted answer the (green checkmark)
require_once('getid/getid3/getid3.php'); //path to your get id file if you do not include this in your file it will result in an error meaning the code will not work
$file = "sade.mp4"; //what you want extract info from maybe mp3,or mp4 file anything you want to get file size in bytes or time duration
$uuuuu = "videos/"; //path to your video file it could also be music not only video
$getID3 = new getID3; //initialize engine
$ThisFileInfo = $getID3->analyze($uuuuu.$file);
getid3_lib::CopyTagsToComments($ThisFileInfo);
echo '<pre>'.htmlentities(print_r($ThisFileInfo, true)).'</pre>'; //use this to print array to pick whatever you like that you want value like playduration, filesize
