deleting old files from a directory

[tommy98]

Hi there, I am trying to build a script that will delete the oldest files from a folder (keep the latest 5 files)

$count = count(glob($Dir . "*"));
if($count > 5){

// delete all old files except the newest 5
}

?

You have to get the last modified date from each file and sort them to find the latest 5.

$last_modified = filemtime("example.txt");

$err = shell_exec('rm `ls -tr | head -n \'-5\'`');

So where abouts in the shell_exec do I specify the root folder?
