PHP Date Sort using scandir()

[vernonw58443027]

I have been racking my brain with this with no obvious solution. For the life of me I cannot sort the following by date. When I run it I get the following output where 2024-02-01 should be before 2024-02-13:

• 2024-01-30
• 2024-02-13
• 2024-02-14
• 2024-02-01

//PATH

$dirPath    = 'INuploads';

// $dirPath contain path to directory whose files are to be listed 

$files = scandir($dirPath); 

//SORT

usort($files);

//PRINT OUT RESULTS

foreach ($files as $file) {

    $filePath = $dirPath . '/' . $file;

    if (is_file($filePath)) {

        echo "<a href='INuploads/$file' target=new>" . $file . "</a>". date ("Y-m-d", filemtime("$dirPath/$file"));

     }

Any suggestions would be greatly appriciated. I have tried many different variotions of this, arsort, sort, ksort

Does this improve anything:

<?php
$dirPath  =  'INuploads';
$files = scandir($dirPath);

function sortFilesFunction($a, $b) {
return strtotime($b) - strtotime($a);
}

sort($files, "sortFilesFunction");

foreach($files as $file) {
if (!in_array($file, array(".", ".."))) {
echo "<p><a href='INuploads/$file' target='new'>$file</a></p>";
}
}

?>
