Clear cache with php

[Fredkl]

My code below to delete cache :
Warning : as it is now when I call the function , I also delete .htaccess file set the pass while calling function to delete what you want , place this file in chat root.

You must set correct permissions on folder 777.

function deleteDir($dir)
{
if (substr($dir, strlen($dir)-1, 1) != '/')
$dir .= '/';

echo $dir.'
';

if ($handle = opendir($dir))
{
while ($obj = readdir($handle))
{
if ($obj != '.' && $obj != '..')
{
if (is_dir($dir.$obj))
{
if (!deleteDir($dir.$obj))
return false;
}
elseif (is_file($dir.$obj))
{
if (!unlink($dir.$obj))
return false;
}
}
}

closedir($handle);

if (!@rmdir($dir))
return false;
return true;

}
return false;
}
if (@opendir('data/public')) {
deleteDir('data/public');
deleteDir('data/private');
echo 'Above cache list has been cleared! - You can close the window';
}else{echo 'Chat cache is already empty!';}

What exactly does deleting the cache do? Does it reset some sort of configuration, or delete the history of all messages, or something else? For that matter, does phpfreechat keep a history of all chats, or just a history of the specified length?

I ask because one of the rooms on my chat freezes from time to time, and I can't figure out how to unfreeze it, but sometimes manage to accidentally. If clearing the cache will quickly solve the problem whenever this happens then that would be very useful, but if it deletes any archives then I wouldn't be so keen.

This function deletes EVERYTHING within the private and public directories. This means that all chat data and logs will be deleted.

It's a great utility when working on your chat and you need to 'wipe the slate' every now and then. Even for production sites, you can always back up your important data and run this function if you ever need to clear out your metadata.
