delete images stored in a directory

[dadamssg]

I'm looking into to creating an image upload option for events, similar to facebook. I run a cron to delete expired events, but i have no idea how i would write code to delete images that are stored in a directory and not just text and numbers in my database. How is this done?

Store the date in the filename, like so:

 

"mysuperawesomeuploadedfile_7-19-09.gif"

 

Aaaand thennn,

 

<?php

$handle = opendir('/path/to/file');

while (false !== ($filename = readdir($handle)))
{
        $splitFileName = explode('_', $filename);
        
        if (end($splitFileName) < date(n-j-y))
        {
        unlink($filename);
        }
}
?>
