How to Retrieve Video Metadata in PHP

Question:

How can I obtain the duration, dimensions, and size of a video file using PHP, regardless of its format?

Answer:

Php does not natively support the retrieval of video metadata. However, external libraries and PHP extensions can be used for this purpose.

Method 1: Using the getID3 Library

The getID3 library (http://getid3.sourceforge.net/) provides methods for extracting metadata from various video formats. To use it:

<code class="php">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 />");</code>

Note: Remember to include the getID3 classes before using this code.

Method 2: FFMpeg PHP Extension

If you have root access to your server, you can install the FFMpeg PHP extension (http://ffmpeg-php.sourceforge.net/) to access more extensive video metadata functionality. Consult its documentation for usage.
