PHP shuffle, multiple loop - php

Question

I want to shuffle 2 loops (or function) in the same correct order, in PHP.
The code currently looks like:
<div class="overlay">
<?php
// Get the list of all files with .jpg extension in the directory and save it in an array named $images
$directory = "uploads/_gallery/*.jpg";
// Create an array of images found in the uploads directory
$images = glob($directory);
// Randomise/shuffle the images
shuffle($images);
foreach( $images as $image ):
if ($image) { ?>
<div class="slide">
<?php echo "<img src='" . $image . "'>"; ?>
</div>
<? }
endforeach;
?>
</div>
<div class="grid">
<?php
// Get the list of all files with .jpg extension in the directory and save it in an array named $images
$directory = "uploads/_gallery/thumbs/*.jpg";
// Create an array of images found in the uploads directory
$images = glob($directory);
// Randomise/shuffle the images
shuffle($images);
foreach( $images as $image ):
if ($image) { ?>
<figure class="unit_25">
<?php echo "<img src='" . $image . "'>"; ?>
</figure>
<? }
endforeach;
?>
</div>
I've tried creating two separate image arrays and merging those with Shuffle, but no luck.

Answer 1

I assume the file has the same name in both directory.
So shuffle $images and then use basename($images) to get the filename :
$directory = "uploads/_gallery/*.jpg";
$images = glob($directory);
shuffle($images);
// For full sized images
foreach ($images as $image) {
// Your stuff
}
// For thumbnails
foreach ($images as $image) {
$basename = basename($image);
$thumbnailPath = "uploads/_gallery/thumbs/". $basename;
// Your stuff
}
