I'm trying to create a cron job that will provide me with a list of files in a directory that have been created or modified in the last day. For the life of me I can't see what is wrong with the code snippet below. It produces nothing and I know that I've updated at least one file in the last 24 hours.

```
<?php

$dir = opendir(".");

clearstatcache();

while(false != ($file = readdir($dir)))
{

if ( substr($file,-4) == ".php" ) 
{
    //echo $file;
    //echo "<br>";

    $yesdate = date('d.m.Y',strtotime("-1 days"));

    if (date("d.m.Y", filemtime($file))==$yesdate)
    {

        echo $file;

    }
    }

}

?>

```
