播放文件夹中的视频

Question

I am trying to make a simple streaming site. That will pay a video from a folder. (mp4). The tricky part is I want to change the video everyday but not the code. So Im wondering if I can use some jquery or php for a global call to look in the folder find the file by the ext and play it.

So essentially instead of renaming the video or changing the codes specific path, I can just change the file thats in the folder, and refresh the page.

What I have so far

Answer 1

Try something like this, assuming there is only one video with the given extension in said folder (otherwise it will get the last occurring file with that extension):

$myVideoDir = '/videos';
$extension = 'mp4';
$videoFile = false;
foreach(scandir($myVideoDir) as $item) {
    if ( $item != '..' && $item != '.' && !is_dir($item) ) {
        $ext = preg_replace('#^.*\.([a-zA-Z0-9]+)$#', '$1', $item);
        if ( $ext == $extension )
            $videoFile = $item;
    }
}

if ( !!$videoFile ) {
    echo '
        <video id="dep" class="center" width="900" height="720" controls>        
          <source src="'.$myVideoDir.'/'.$videoFile.'" type="video/mp4"> 
        </video>
    ';
}

Answer 2

$myVideoDir = '/videos';
$extension = 'mp4';
$videoFile = false;
foreach(scandir($myVideoDir) as $item) {
    if ($item != '..' && $item != '.' && !is_dir($item)) {
        $ext = preg_replace('#^.*\.([a-zA-Z0-9]+)$#', '$1', $item);
        if ($ext == $extension) $videoFile = $item;
    }
}
if (!!$videoFile) {
    echo ' <video id="dep" class="center" width="900" height="720" controls> <source src="'.$myVideoDir.
    '/'.$videoFile.
    '" type="video/mp4"> </video> ';
}
