Shuffle and display images from a directory in PHP

I'm trying to get the uploaded images from a directory and shuffle their order. I'm able to get the images and display them in order quite easily but can't seem to get them shuffled! 

<?php 
    $imagesDir = 'uploads/';
    $images = glob($imagesDir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);
    $randomImage = $images[array_rand($images)]; 
?>

<div id="images">
        <?php
            $print_r($images);
            $shuffleimages = shuffle($images);
            foreach($shuffleimages as $shuffleimage) {
                echo '<img src="'.$shuffleimage.'" />';
            }
        ?>
</div>

When I print $images I get:

Array (

[0] => uploads/image1.jpg

[1] => uploads/image2.jpg

[2] => uploads/image3.jpg

[3] => uploads/image4.jpg

[4] => uploads/image5.jpg

)

I don't know if it's something to do with the glob function or how I'm retrieving the images more generally? I've looked around other questions on SO but can't seem to see what I'm doing differently/wrong!

You also may use sacndir and use the sorting_order parameter to shuffle files by sorting them.

You are going one step too far .. There is no need to reassign $images ... Your $shuffleimages will only return a boolean of true or false

    <?php
        shuffle($images); // $images will be shuffled.
        foreach($images as $shuffleimage) {
            echo '<img src="'.$shuffleimage.'" />';
        }
    ?>
