html5 - Randomly Generate Multiple Files From Directory with PHP -

i building website people can go , upload images, gifs, , videos. on home page, want list files @ random upload directory.

<article class="item thumb" data-width="384">     <h2><?php echo $file_title;?></h2>     <a href="<?php echo $randomimage ?>"><img src="<?php echo $randomimage ?>" alt=""></a> </article>  <article class="item thumb" data-width="274">     <h2><?php echo $file_title;?></h2>     <a href="<?php echo $randomimage ?>"><img src="<?php echo $randomimage ?>" alt=""></a> </article> 

and total of 5 times. $randomimage generated code:

<?php    $imagesdir = 'uploads/';    $images = glob($imagesdir . '*.{jpg,jpeg,png,gif}', glob_brace);    $randomimage = $images[array_rand($images)];    $file_title = $randomimage; ?>  

i want able add feature user scrolls down, more , more of these articles containing images show up, each containing random not shown file. how can display files @ random without having manually enter unique variables?

p.s. right not have files stored in database.

remove randomly selected image $images before select another.

loop 5 images

<?php // files  $imagesdir = 'uploads/'; $images = glob($imagesdir . '*.{jpg,jpeg,png,gif}', glob_brace); $imagescount = count($images);  for($i = 0 ; $i < $imagescount ; $i++) {      // select image       $randomindex = array_rand($images); // select image index      $file_title = $randomimage = $images[$randomindex]; // use selected image      unset($images[$randomindex]); // remove selected image     // print_r($images); // can see left in $images      // show image      ?>     <article class="item thumb">         <h2><?php echo $file_title;?></h2>         <a href="<?php echo $randomimage ?>"><img src="<?php echo $randomimage ?>" alt=""></a>     </article>     <?php } ?>
