getID3 supports video formats. See: http://getid3.sourceforge.net/

getID3 支持视频格式。见：http: //getid3.sourceforge.net/

Edit: So, in code format, that'd be like:

编辑：所以，在代码格式中，就像：

include_once('pathto/getid3.php');
$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 />");

Note:You must include the getID3 classes before this will work! See the above link.

注意：您必须包含 getID3 类才能生效！请参阅上面的链接。

Edit: If you have the ability to modify the PHP installation on your server, a PHP extension for this purpose is ffmpeg-php. See: http://ffmpeg-php.sourceforge.net/

编辑：如果您有能力修改服务器上的 PHP 安装，用于此目的的 PHP 扩展是 ffmpeg-php。见：http: //ffmpeg-php.sourceforge.net/

If you have FFMPEG installed on your server (http://www.mysql-apache-php.com/ffmpeg-install.htm), it is possible to get the attributes of your video using the command "-vstats" and parsing the result with some regex - as shown in the example below. Then, you need the PHP funtion filesize() to get the size.

如果您的服务器上安装了 FFMPEG（http://www.mysql-apache-php.com/ffmpeg-install.htm），则可以使用命令“ -vstats”获取视频的属性并解析结果与一些正则表达式 - 如下面的示例所示。然后，您需要 PHP 函数 filesize() 来获取大小。

$ffmpeg_path = 'ffmpeg'; //or: /usr/bin/ffmpeg , or /usr/local/bin/ffmpeg - depends on your installation (type which ffmpeg into a console to find the install path)
$vid = 'PATH/TO/VIDEO'; //Replace here!

 if (file_exists($vid)) {

    $finfo = finfo_open(FILEINFO_MIME_TYPE);
    $mime_type = finfo_file($finfo, $vid); // check mime type
    finfo_close($finfo);

    if (preg_match('/video\/*/', $mime_type)) {

        $video_attributes = _get_video_attributes($vid, $ffmpeg_path);

        print_r('Codec: ' . $video_attributes['codec'] . '<br/>');

        print_r('Dimension: ' . $video_attributes['width'] . ' x ' . $video_attributes['height'] . ' <br/>');

        print_r('Duration: ' . $video_attributes['hours'] . ':' . $video_attributes['mins'] . ':'
                . $video_attributes['secs'] . '.' . $video_attributes['ms'] . '<br/>');

        print_r('Size:  ' . _human_filesize(filesize($vid)));

    } else {
        print_r('File is not a video.');
    }
} else {
    print_r('File does not exist.');
}

function _get_video_attributes($video, $ffmpeg) {

    $command = $ffmpeg . ' -i ' . $video . ' -vstats 2>&1';
    $output = shell_exec($command);

    $regex_sizes = "/Video: ([^,]*), ([^,]*), ([0-9]{1,4})x([0-9]{1,4})/"; // or : $regex_sizes = "/Video: ([^\r\n]*), ([^,]*), ([0-9]{1,4})x([0-9]{1,4})/"; (code from @1owk3y)
    if (preg_match($regex_sizes, $output, $regs)) {
        $codec = $regs [1] ? $regs [1] : null;
        $width = $regs [3] ? $regs [3] : null;
        $height = $regs [4] ? $regs [4] : null;
    }

    $regex_duration = "/Duration: ([0-9]{1,2}):([0-9]{1,2}):([0-9]{1,2}).([0-9]{1,2})/";
    if (preg_match($regex_duration, $output, $regs)) {
        $hours = $regs [1] ? $regs [1] : null;
        $mins = $regs [2] ? $regs [2] : null;
        $secs = $regs [3] ? $regs [3] : null;
        $ms = $regs [4] ? $regs [4] : null;
    }

    return array('codec' => $codec,
        'width' => $width,
        'height' => $height,
        'hours' => $hours,
        'mins' => $mins,
        'secs' => $secs,
        'ms' => $ms
    );
}

function _human_filesize($bytes, $decimals = 2) {
    $sz = 'BKMGTP';
    $factor = floor((strlen($bytes) - 1) / 3);
    return sprintf("%.{$decimals}f", $bytes / pow(1024, $factor)) . @$sz[$factor];
}

If you use Wordpress you can just use the wordpress build in function with the video id provided wp_get_attachment_metadata($videoID):

如果您使用 Wordpress，则可以使用带有wp_get_attachment_metadata($videoID)提供的视频 ID 的 wordpress 内置函数：

wp_get_attachment_metadata($videoID);

helped me a lot. thats why i'm posting it, although its just for wordpress users.

帮了我很多。这就是我发布它的原因，尽管它仅适用于 wordpress 用户。

https://github.com/JamesHeinrich/getID3下载 getid3 zip，而不是仅将 getid3 命名文件夹复制粘贴到项目文件夹中并使用它，如下所示...

<?php
        require_once('/fire/scripts/lib/getid3/getid3/getid3.php');
        $getID3 = new getID3();
        $filename="/fire/My Documents/video/ferrari1.mpg";
        $fileinfo = $getID3->analyze($filename);

        $width=$fileinfo['video']['resolution_x'];
        $height=$fileinfo['video']['resolution_y'];

        echo $fileinfo['video']['resolution_x']. 'x'. $fileinfo['video']['resolution_y'];
        echo '<pre>';print_r($fileinfo);echo '</pre>';
