How to display images to delete using PHP Unlink - php

Question

I have a script that deletes images from a folder using PHP.
The problem is the images arenot being displayed on the page.
My code is as below
<?php
// directory separator
defined("DS")
|| define("DS", DIRECTORY_SEPARATOR);
// root path
defined("ROOT_PATH")
|| define("ROOT_PATH", realpath(dirname(__FILE__)));
// upload folder directory
defined("UPLOAD_DIR")
|| define("UPLOAD_DIR", "uploads");
// path to the upload folder
defined("UPLOAD_PATH")
|| define("UPLOAD_PATH", ROOT_PATH.DS.UPLOAD_DIR);
function getAllFiles($folder = null) {
if(!empty($folder) && is_dir($folder)) {
if($handle = opendir($folder)) {
$out = array();
while($file = readdir($handle)) {
if(is_file($folder.DS.$file)) {
$out[] = $file;
}
}
closedir($handle);
return $out;
}
return false;
}
return false;
}
$files = getAllFiles(UPLOAD_PATH);
if (!empty($_POST['file'])) {
foreach($_POST['file'] as $file) {
unlink(UPLOAD_PATH.DS.$file) or die("Failed to <strong class='highlight'>delete</strong> file");
}
header("location: " . $_SERVER['REQUEST_URI']);
}
?>
<?php if (!empty($files)) { ?>
<form name="form1" method="post">
<?php foreach($files as $key => $file) { ?>
<label for="file_<?php echo $key; ?>">
<input type="checkbox" name="file[]" id="file_<?php echo $key; ?>" value="<?php echo $file; ?>" />
<?php echo $file; ?>
</label>
<?php } ?>
<input type="submit" name="delete" value="Delete" />
</form>
The code works fine to delete the images but does not display the images on the page.
Your help is much apprecited.
Thank You

I think the images are still in the browser cache, so deleting the cache will result in not seeing any deleted images.
