Not able to display video in PHP - php

Question

On my site, users are able to upload videos.
And I am storing that videos in a folder and their path in the mysql database.
I want to retrieve that videos from the folder and get display on the page.
That folder also contains images.
I am showing that images also.
Images are getting displayed. And videos only play audio, and not the video. And also, I have only two videos in my database and one image. Then also 3 video files and 3 image are getting display, from which two images are displayed with alternate text.
Following is the code I tried in PHP:
if ($db_found)
{
$query ="SELECT * FROM `files`";
$result = mysql_query($query,$db_handle);
echo "<div class='product'>";
while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
$src=$row['File'];
echo "<img src='$src' height='200' width='200' alt='Image not Found'/>";
echo "<video width='200' height='200' autoplay controls>
<source src='$src' type='video/mp4'>
</video>";
}
echo "</div>";
}

Answer 1

You need to check which are videos and which are images using something like:
$src=$row['File'];
if (preg_match("/\.jpg$/i",$src)){
echo "<img src='$src' height='200' width='200' alt='Image not Found'/>";
}else{
echo "<video width='200' height='200' autoplay controls> <source src='$src' type='video/mp4'> </video>";
}
Edit
Oh and please stop using the deprecated mysql functions
Choose a more modern method of connecting to the db

Answer 2

You really should add (at the very least) some way to separate your videos and images. For example, a second column in your files table that tells you if the file in question is a video or image.
Then you can simply do something like this:
SELECT * FROM `files` WHERE `filetype` == 1
Where 1 = image, 2 = video, etc.
Then you can simply process that array as you please:
<?php
foreach($images as $image) { ?>
<img src='<?= $image["src" ?>' alt=''>
<?php } ?>
And
<?php
foreach($videos as $video) { ?>
<video id="video" preload="auto" autoplay="autoplay">
<source src="<?= $video["src"] ?>.mp4">
</video>
<?php } ?>
Note: The fact that only audio is playing on your videos has NOTHING to do with your code.
